IRCOL Collimators

Test bench for visible to infrared cameras, laser range finders, and Day/ Night goggles

Versatile complete test bench for all electro-optical systems

The IRCOL series are test equipment for the characterization and the performance validation of a wide array of electro-optical sensors: visible cameras, CCD and ICCD cameras, day/night goggles, NIR, SWIR, MWIR, LWIR imagers and laser rangefinders.

The IRCOL series are designed on a modular concept, each brick is selectable depending on the electro-optical sensor to be tested.

Wide range of focal lengths and apertures


All HGH reference sources, black bodies and integrating spheres, can be located at the focus of the collimator.

Main benefits of the IRCOL collimators :

  • A wide range of optical projectors compatible with the test requirements for all standard cameras and laser range finders: Ø 150 to 600 mm clear aperture off-axis collimator Ø Focal length from 750 to 6000 mm
  • UV and Visible to far IR operating spectral bandwidth depending on coatings: aluminium, silver or gold available
  • Output wavefront map supplied
  • Motorized wheel with interchangeable targets
  • Tests along vertical and horizontal axes with only one target
  • High repeatability of target positioning
  • Robust mechanical structure with a protective cover of the optical components against shocks, dust and stray light
  • Background temperature accurately measured thanks to a calibrated Pt sensor
  • Exhaustive range of targets and options for electro-optical system testing
  • Short delivery time

Main applications :

  • Visible to SWIR cameras: effective focal length, resolution (MRC), distortion, field of view, latency.
  • Thermal imagers: spatial resolution (LSF/MTF), MRTD and DRI ranges, alignment of optical axis vs; mechanical axis.
  • Multi-sensor gimbaled systems: alignment of axes, large apertures compatible.
  • Laser rangefinders and designators: alignment, beam profiling, divergence, accuracy of distance measurement, laser pulse energy and power
  • Night vision devices: gain, resolution, infinity focus, zero and range of eyepiece, parallelism of goggles axes, figure of merit, spot defect
