TEST & MEASUREMENT
A complete range of reference infrared sources
Blackbodies are reference sources used for testing infrared systems.
Main applications include calibration of thermographic sensors and cameras, qualification of thermal imagers and production lines of IR detectors and cores. In laboratory or on the field, they are part of the electro-optical test benches for the characterisation of complex optronic systems. Our blackbodies range include:
The HGH integrating sphere sources are an international reference in terms of reliability and ease of use. They cover the UV, Visible and SWIR spectra and are adapted to all your testing needs for your electro-optical systems, thanks to their their uniform, calibrated and ultra stable radiation.
Universal & easy to use test software for cameras & detectors
INFRATEST is a powerful software for testing visible, NIR and IR cameras, ICCDs, goggles and laser rangefinders.
Optical collimators and universal electro-optical test bench
HGH’s projectors are optical collimators consisting of an off-axis parabolic mirror and a plane folding mirror offering high on-axis performance with no obscuration. A variety of VIS/NIR/SWIR/MWIR/LWIR sources can be accomodated on our optical collimators at the focal plane.
Universal qualification bench for Focal Plane Arrays
- NETD, detectivity, linearity, responsivity
- Bad pixel location and non-uniformity correction
- Crosstalk, MTF
- Spectral response
The OPAL collimator is a compact and versatile portable test bench enabling the maintenance in the field of many electro optics devices such as night vision goggles, visible to IR cameras and lasers.
Night Vision Device Testing
HGH’s Night Vision Test sets are the new standard for digital night vision goggle testing. Discover the NV-2500 and NV-2020 to test autonomously your night vision goggles.
Veiling Glare Index Test is a measurement of the image obscuring light scatter in a lens system done by determining the contrast between black and white target areas.
