OPAL

Field multispectral test bench for optical devices

A versatile and compact test bench for the maintenance of military equipment

OPAL is a multispectral portable bench dedicated to the test and the maintenance of military EO devices.

It has been designed to be robust and very easy to use, be it in a lab or on the field.

OPAL is based on a compact collimator for field application and includes infrared and visible reference sources such as a blackbody and an integrating sphere, as well as specific targets and filters.

The OPAL collimator is the result of our long experience in the maintenance of military electro-optics systems. The field-proven COPI test bench as well as the world renowned NV-2500 and NV-2020 night vision testing systems are part of this product range.

OPAL

OPAL is compatible with all light military field optical devices:

The modular and versatile configuration of OPAL, associated with dedicated exhaustive test software and ruggedized PC, make it compatible with the main EO devices on the market. It enables the testing of:

• Thermal & SWIR imagers (1-2.5µm/ 3-5µm/ 8-14µm)
• Night vision goggles
• TV cameras or day goggles
• Laser rangefinders and illuminators
• Multispectral portable devices
• Weapon sights and clip-on equipped with Thermal, Intensifier Tubes and LRF modules
