IR-Detectors
Detecting IR-electromagnetic radiation
An IR-Detector is a sensor that registers light or other electromagnetic energy in the infrared wavelength region. There are several material types and technologies to detect and measure light in this domain, all with their specific characteristics.
Nanor offers high-performance IR-Detectors based on InGaAs, known for low noise and high sensitivity, and PbS/PbSe used for a wider spectral range with highest sensitivity.

More information
Indium Gallium Arsenide (InGaAs) detectors measure optical power in the Near Infra-Red (900 – 2200 nm) region. Having high-speed and high sensitivity, an InGaAs detector is the choice for optical fiber telecommunications, compound analysis and process control. These come in many different packages and variations, suitable technology for high volume applications.
PbS/PbSe
Technical information
- Wavelengths: 1 – 5 µm
- Single to multi element detectors
- Very High Sensivity
- Cooled and uncooled options
Links
More information
A PbS detector measures in the standard SWIR range (1 – 3 µm) and PbSe is used for the MWIR range (1 – 5 µm). These detectors are ideal for gas analysis, emissions monitoring, spectroscopy, process control and fire monitoring and you can choose from wide variety of active area sizes, cooling alternatives, packaging, windows, lenses, and filters options.
InAs/InAsSb
Technical information
- Wavelengths: 2-5.5 µm
- Very High Sensitivity
- Cooled and uncooled
- RoHS compliant – Cadmium and Mercury free
Links
More information
These detectors are temperature stable up to 300°C and mechanically durable. The devices can operate either at flicker-free zero bias or with reverse voltage. Offered in a wide variety of Uncooled and TE cooled versions, packages, active areas and lenses. Ideal for gas analysis and monitoring and spectroscopy.
Additionally, MWIR and LWIR Type II superlattice photoconductive and photovoltaic detectors are available, operating at room temperature or thermoelectrically cooled and achieve excellent parameters without cryogenic cooling (LN2).
All InAs/InAsSb are free of mercury or cadmium and such RoHS compliant.
HgCdTe (MCT)
Technical information
- Wavelengths: MWIR (3-8μm) and LWIR (8-16μm)
- Very High Sensitivity and fast response time
- Cooled and uncooled
- Large area
Links
More information
These IR-Detectors are based on HgCdTe material which offers the highest performance out of all discovered materials suitable for infrared detection. This type of detector is great for use in creating gas sensors for industry and environmental protection. Additionally, as they have very high parameters of detection and speed of operation applications such as leak detection, transport safety or defense applications are ideal. Moreover, you can find these detectors ideal for solution such as CRDS, TDLAS or FTIR spectroscopy.
