Lightpath offers custom lens assemblies for the challenging requirements of mid-wave infrared (MWIR) imaging systems.  These systems typically have cooled dewars with custom geometries including a cold stop, window, and optional filters that must be taken into consideration for proper optical design and optimal performance.  Stray light control and narcissus minimization must also be considered in the optical and mechanical design process, as cooled systems have a higher sensitivity to these effects than uncooled imagers.

Lightpath utilizes state-of-the-art materials and manufacturing techniques to maximize performance while also considering design-for-manufacturability and SWaP constraints.  Our expertise in diamond-turning allows us to take advantage of aspheric performance enhancements with the fewest number of lens elements.  In addition, our wide selection of materials, including novel chalcogenide glass, enables optimal chromatic, thermal, and mechanical (SWaP) properties to be custom designed to match each application.
