Wide Field of View Collimators

Wide Field of View Collimator
Wide Field of View Collimator

The wide field of view IR test collimator, is used to test thermal imagers in their wide field of view mode of operation. Typical applications include navigational FLIR’s and commercial imagers.

CI’s unique compact WFOV is a refractive IR collimator combined with an accurate IR source (CI’s SR 800-2D) and a target wheel. The WFOV provides the means to perform IR testing such as; MTF, NETD, MRTD etc.

Blackbody temperature and target wheel position can be manually controled using the blackbody controler or using a computer via the IEEE-488 or RS232 communication. The WFOV is fully compatible with CI’s Automatic FLIR Test Software.
