The MWIR spectral range enables true night vision for medium and long range imaging. Some of its benefits include:
- High sensitivity for passive thermal imaging in complete darkness (blackbody emission only, without illumination)
- High thermal contrast (low NETD), ideal for scenes with high level of clutter
- High atmospheric transparency for long-range observation
- High Operating Temperature (HOT) Focal Plane Arrays (FPA) enable lower Size, Weight and Power (SWaP) and long Mean Time To Failure (MTTF) solution compared to LWIR
- Shorter wavelength enables smaller optics and higher F-numbers compared to LWIR for high resolution thermal imaging
SCD is one of the leading suppliers of cooled MWIR infrared detectors. With over forty years of R&D and production, our capabilities include:
- Mature InSb technology for the full MWIR spectrum, extendable to shorter wavelengths including SWIR and NIR
- XBn-InAsSb Barrier detector technology with low SWaP and long MTTF, operating at high temperatures (150K) in the highly transparent part of the MWIR spectrum (3.6 – 4.2µm)
- Broadband spectral response, down to NIR
- Multi-function ROIC with laser pulse detection functions (ALPD, TLRF)
- Very large array formats with small pitch
- Variety of packaging and electronic solutions
- Low SWaP video-engine
SCD’s MWIR infrared detectors are integrated in high end and low SWaP military and commercial applications, such as:
- Hand-held cameras and weapons sights
- Missile Warning Systems (MWS)
- Infrared Search and Track (IRST)
- Missile seekers
- Miniature payloads
- 24/7 surveillance
- Gas leak detection
- Airborne Enhanced Vision Systems (EVS)
- Spectrometry
- Non-destructive testing
