HGH Infrared Systems has introduced largest collimator ever built to test very long focal length visible and IR cameras, the IRCOL600/6000. The French company developed and manufactured this collimator, which integrates high quality optical parts assembled into an autonomous and robust mechanical structure, in its Igny based headquarters close to Paris.

HGH Infrared Systems designs and provides IR test equipment, to universities, research labs, camera manufacturers and test centers around the world. The HGH IRCOL Collimators Series are used for the characterization and the performance validation of visible cameras, night vision cameras, goggles, NIR, SWIR, MWIR, LWIR imagers or even laser rangefinders. The company manufactured the IRCOL600/6000, a collimator of unprecedented performances, bearing witness to their innovation spirit.

With a true optical aperture of 600 millimeters and a focal length of six meters, the IRCOL600/6000 is designed to test very long focal length visible & infrared systems, through the simulation of spatial frequencies up to 50 cy/mrad, and to assess the most demanding electro-optical systems with the highest resolution. Driven by the INFRATEST software, the collimator includes a DCN1000 blackbody and an ISV integrating sphere to cover a wavelength range from infrared to visible.

According to Catherine Barrat, Head of the Test & Measurement department at HGH Infrared Systems, the collimator is made of very high quality optical components, with exceptional sizes and weights. The HGH technical team has successfully completed the challenge of integrating them, conferring excellent optical properties to a rather compact structure.

HGH is currently exhibiting at QIRT 2018 in Berlin from June 25 -29 where they are showcasing a new generation of blackbodies and their advanced electronic controllers.
