Strix Lenses
This line has a slower F# while having similar aspects to the Surnia line. The design supports camera systems with a stop, and longer back working distance, (BWD) which is common for cooled systems or detectors requiring a radiation shield. However, it can be adapted to most LWIR cameras. If your imager meets the criteria, however size is a concern, consider the Strix.
