A Custom Solution for MWIR In-Situ Optical Testing

Our defense client produced Intelligence, Surveillance, and Reconnaissance (ISR) infrared optical systems that required in-situ testing of the assemblies. This requirement called for delivery of an interferometric test beam into the large focal plane pod-mounted or fixture-mounted electro-optical system.

A custom Mid-Wave Infrared (MWIR) interferometer system was required since commercially available testing systems couldn’t meet the beam delivery requirements. The program required a quick development cycle to bring our customer’s production online.

Optikos competed against other prominent optical metrology groups, and won this contract by proposing a custom-designed MWIR Twyman-Green interferometer with an elevated platform and an articulating optical arm with accessories optics. This created a nearly infinitely adjustable beam positioner. The entire system was floated on air bearings to provide capability for one operator to easily position the interferometer and its beam delivery system to the focal plane inside the unit under test.

The new MWIR interferometer was delivered on-time, on-budget, and was instrumental in creating a flexible, user-friendly testing platform for the product testing group. Optikos has received subsequent orders for the instrument to further augment the testing and production area capability.
