SHORTWAVE INFRARED (SWIR) MARKET OVERVIEW

The global shortwave infrared (SWIR) market size was USD 0.84 billion in 2025 and is projected to reach USD 1.53 billion by 2034, exhibiting a CAGR of 6.8% during the forecast period.

Shortwave infrared (SWIR) imaging occupies an approximate spectral band of 0.9252.5 mm with relating to the visible and mid-infrared spectra’s, permitting contrast and material discrimination, invisible within visible camera applications, including under some coatings, moisture, plastics and spectral material identification. SWIR systems are an integration of detectors (InGaAs, colloidal quantum dots, CMOS based solutions), optics, lighting and processing to achieve applications in semiconductor and electronics inspection, night vision, quality control in recycling/plastic sorting, agricultural sensing and spectroscopy and monitoring industrial processes. Recent progresses lower cost uncooled sensors, volume production of quantum-dot SWIR cameras, and a closer interface to machine vision pipelines has pushed SWIR out of their defense/science niche to more widespread use in a commercial and industrial context. Simultaneously, declining component prices, increased pixel density and new form factors (snapshot arrays, miniature modules and fast line scan cameras), are facilitating implementation in automated inspection lines, robotics and some automotive sensing prototypes. According to market research companies, consistent multi-year CAGR forecasts show as manufacturers and systems integrators continue to offer increasingly diverse offerings and encourage new entrants to invest in lower-cost SWIR modules, budget-driven end-user traffic is being pulled by semiconductor fabs, recycling and food inspection, and additional investment by defense and security initiatives. Broadly, SWIR currently is moving out of specialty instrumentation into a general highly developed imaging technology whose applications are increasing accelerating as well as its levels of production.

COVID-19 IMPACT

Shortwave Infrared (SWIR) Market Had a Negative Effect Due to Supply Chain Disruption During COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The shortwave infrared (SWIR) market share was hit by a series of short-term negative factors during the COVID-19 pandemic: Slowdowns in global supply-chains disrupted production of key detector materials (InGaAs wafers and specialty optics), delayed logistics increased lead times on cameras and modules, the majority of industrial customers curtailed capital investments or overall spending discretionary investments slowing down acquisitions to factory inspection and customer-non-mission-critical deployments. Integrators and startups were forced to postpone or downsize field trials or R&D programs because companies constrained budgets and redistributed resources to pandemic response or tooling to work remotely; and stretched cash flows pushed small companies to product delays and sluggish commercialization timelines. Simultaneously, lockdowns reduced to a temporary zero certain commercial and scientific demand underlying the long-lead scientific acquisitions. But COVID also reinforced use cases that made some sensing solutions more interesting (remote monitoring, contactless inspection and automated sorting) and parts of the producer that survived the early shocks spurred investment in supply diversification and local inventory buffering. Recovery plus-reshape implied a temporary shrinkage and then more rapid recovery after factories and logistics got back to normal, but the lesson was that single-source suppliers were thoughtful and prioritized resilient supplies and modular structures.

LATEST TRENDS

Democratization of SWIR: low-cost quantum-dot and CMOS approaches are pushing SWIR from specialist labs into high-volume industrial lines Drives Market Growth

One recent development that has caused a tremendous acceleration is the rush to achieve an affordable approach to SWIR sensing with required volumes in the same SIC as visible and NIR cameras. SWIR previously used mere hundreds of costly InGaAsfocal-plane arrays; lower-cost arrays based on colloidal quantum dots (CQD) and processes compatible with CMOS are now available and can be integrated into small modules capable of factory-wide application and edge devices. This is shown by strategic moves in the industry: semiconductor and sensor incumbents are acquiring or forming alliances with quantum-dot and new SWIR experts to integrate SWIR with large-scale sensing portfolios, and camera makers are introducing higher-resolution ruggedized SWIR products whose primary applications are in industrial inspection and military uses. The technological shift to snapshot and high-frame-rate line-scan SWIR cameras, with software stacks to integrate SWIR spectral sensitivity with machine-vision algorithms, is fueling new application wins in semiconductor inspection, plastics sorting and moisture/quality sensors in food cleaning. That mix of maturing technologies, vertical capability among large sensor companies, and declining unit pricing is now rendering SWIR economical to applications that were previously uneconomical, and creating wider commercial deployment opportunities.

SHORTWAVE INFRARED (SWIR) MARKET SEGMENTATION

By Type

Based on type, the global market can be categorized into Area Scan, Line Scan

• Area Scan: Area-scan or SWIR cameras read 2D frames (full images) and are best used in snapshot imaging, general machine vision and scene capture when location information is important. They are applied in discrimination of material, surveillance system, research, and handsets. Area cameras are available in a host of resolutions and frame rates to trade off sensitivity and throughput.

• Line Scan: Line-detection SWIR cameras can capture a single line of pixels in a short amount of time and can be utilized on high-speed web inspection, conveyor-belt inspection, and spectral scan (pushbroom). They have extremely high line rates and do extremely well when objects pass behind a fixed imaging head. There is a trend to use line-scan systems in conjunction with illumination and precision motion control to perform micron-scale inspection.

By Application

Based on Application, the global market can be categorized into Scientific Research, Commercial, Industrial, Medical, Military & Defense, Others

• Scientific Research: Research regimes emphasise sensitivity, calibratability and spectral fidelity; typically they include cooled detectors, bench optics and custom software. They can be used in spectroscopy, astronomy and laboratory research. These systems are focused on flexibility and absolute measurement accuracy rather than cost.

• Commercial: SWIR commercial products aim at general business use which includes inspection and the quality of any product or process and automated sorting. These provide easier integration, industrial packaging and in-between costs. The objective is fast, dependable imaging good enough to be used in production areas.

• Industrial: In the field of semiconductor inspection, recycling, pharmaceutical QC and process monitoring, industrial SWIR applications are hardened, non-stop systems installed in lines. They are concerned about throughput, repeatability and less downtime. In many industrial models PLCs and factory networks have deterministic interfaces.

• Medical: In medicine SWIR may find use in tissue contrast, vein visualization and some diagnostic imaging where differences in absorption are informative. Consumables need certified routes and testing. Physiological SWIR applications moderate safety, repeatability and interpretability.

• Military & Defense: Military applications fall into two categories; night vision, target detection, surveillance and missile seeker improvement, currently taking advantage of the capability of SWIR to penetrate the smoke/atmospheric scattering and achieve contrast low-light. Such systems require lengthy lifecycles, hardened nodes and safe supply chains. The pioneer SWIR investments were historically supported by military demand.

• Others: Other verticals include research instrumentation, environmental sensing, agriculture (hyperspectral SWIR for plant stress), and consumer experiments (prototype automotive/night-vision concepts). Many “other” uses are emerging as sensors get cheaper and software analysis improves. These are often early-adopter or pilot deployments.

MARKET DYNAMICS

Driving Factors

Industrial automation & semiconductor inspection driving SWIR adoption Boost the Market

One major driving force is that non-destructive, high-contrast inspection processes are in demand in semiconductor fabs and high precision manufacturing. shortwave infrared (SWIR) market growth exposes flaws and layer variations not visible under light: e.g., underground flaws, uniformity of layers, wafer coating issues and silicon backside characteristics, make defects detectable earlier and increase production. SWIR separates the types of polymer and impurities present in recycling and plastics sorting, which produces purer products, thereby saving on the cost of manual sorting. SWIR cameras combined with machine-vision analytics are delivering production-to-use defect flags with factories moving toward greater automation and inline quality assurance. Innovation in camera resolution and speed (with high-frame-rate area cameras and very high-speed line-scan modules) implies that SWIR can satisfy throughput requirements. Volume-manufactured detectors and modular cameras fit with current machine-vision ecosystems, making SWIR a viable option in fabs and industrial lines that require yield, traceability and minimized waste.

Defense, security and night-time sensing fueling sustained investment Expand the Marke

Defense and security also continue to be robust and long-term demand drivers to SWIR due to the benefits of the band in night time imaging, target identification using aerosols and use alongside laser systems. Governments are investing in better situational awareness, reconnaissance and situational-target-acquisition sensors that can work where direct imaging is ineffective. SWIR can be combined with active illumination (eye-safe lasers) and can operate within spectral windows that survive smoke or camouflage, which combined with minimal size makes it appealing to surveillance, EO/IR sensor suites and seeker heads. Such defense purchases often support early technology development and bulk buy runs and subsequently free up to spin-out commercially. Also, the presence of dual-use programs (defense + commercial) motivates suppliers to continue investing in ruggedization, sensor stabilization and system integration - strength that maps directly to industrial and commercial products. Hence, defense budgets ensure revenue and credibility that help spur faster expansion of the SWIR ecosystem at large scale.

Restraining Factor

High detector and system cost still limits large-scale commoditization Potentially Impede Market Growth

Traditionally, there has been a cost premium associated with the InGaAs FPAs and precision SWIR optics, relative to visible/NIR cameras; the unit cost of high-performance SWIR is, even with emerging CQD and CMOS-compatible methods, still exorbitantly more expensive than mainstream cameras in machinery-vision. Such a difference in cost delays adoption in small-to-mid sized Businesses and in applications that are price sensitive. A combination of costs (optics, illumination, interfaces) and custom calibration and software requirements add to the overall solution cost. In the near future, most likely potential users will consider cost-effective NIR/visible solutions or hybrid sensing solutions over costly SWIR devices, meaning that market penetration into less profitable markets will be constrained until the development of affordable, but high-yield, cost-effective detectors and a well-established secondary marketplace in the SWIR optics/lenses.

Mass-market inspection & recycling can unlock high-volume uptake Create Opportunity for The Product in The Market

Opportunity

Another potential opportunity is the expansion of SWIR to mass, dense application inspection configurations - e.g., plastics sorting to recycle, food-quality measurement, and in-line pharmaceutical inspection. These verticals have already measured ROI on better purity, fewer recalls and increased quick throughput. Should suppliers keep decreasing sensor prices, and do offer to integrate, turnkey modules, with standard machine-vision interfaces, system integrators will be able to implement SWIR on a significant number of production lines.

Cooperation between sensor manufacturers and major industrial integrators/recycling equipment manufacturers might develop packaged products that integrate optics, lighting and AI models to focus on typical defects - volume integration can increase faster, and deployment expenses per system can be reduced.

Material supply & specialized manufacturing constrain scaling Could Be a Potential Challenge for Consumers

Challenge

SWIR manufacturing has been scaled around SEM (InGaAs wafers, epitaxy and CQD supply chains) and optical manufacturing (precision sizes); supplier shortages or monopolies introduce supply constraints and geopolitical supply risks. The migration to new technologies (CQD, CMOS-compatible SWIR) must entail new tooling in the production process, qualification, and reliability testing - again time as well as capital intensive.

These supply-chain limitations are especially sensitive to defense buyers due to certification and security issues. To support increased demand manufacturers, have to invest in diversified suppliers, local capacity, and qualification pipelines, otherwise price volatility and lead-time delays will make adoption slow, even when product demand is high.

KEY INDUSTRY DEVELOPMENT

July 2024: On semi completed the acquisition of SWIR Vision Systems (a CQD-based SWIR technology provider), signaling consolidation and strategic vertical integration of quantum-dot SWIR capabilities into a large CMOS image-sensor supplier.

REPORT COVERAGE

SWIR will take a turn: technology (quantum-dot sensors, better InGaAs arrays, technologies making SWIR CMOS-compatible) and increasing software solutions with machine vision will change SWIR, seen as a niche with a very high cost, into a more-welcoming, more-reliable, more-qualified commercial technology in industrial inspection, recycling, quality control in food and pharmaceuticals, and (technological application) defense. The market research shows generally good CAGR and growth of market value over the next few years which will support the story on the cost curves and form factor innovations that facilitate the ability to roll out to wider adoption. Ongoing lowering of the prices of the detector, increasing use of turnkey camera modules ready to have machine-vision interfaces and collaboration between sensor houses and integrators are key enablers. Adoption is moderated, however, by pre-existing cost differentials, specialized supply-chain requirements on detector materials, and the time and investment necessary to certify SWIR-based solutions in regulated markets (medical, aerospace) and. In the case of investment rooms and product teams, the way forward in the near-term is modular software-enabled SWIR solutions that cater to concrete ROI applications (yield enhancement, sorting precision, defect detection), locally secure supply chains, and bring large integrators on board to help them roll out quicker. Eventually, with commercial trials and government support of R&D in mass production, the price will come down and the addressable market will expand, making SWIR a standard product in the industrial imaging toolset rather than the rare specialty product.
