Each NightcrawlIR lens is ruggedized for tactical application with a sealed front lens flange interface and additional features for convenient payload, enclosure, and Dewar installation.
All lenses ship standard with our StingWare™ Controller featuring:
Metric zoom and focus mechanisms offering positioning precision and repeatability.
Temperature adjusted focal length and object distance queries.
Active athermalization functionalities.
The controller utilizes integrated hardware on the lens cells to minimize system hysteresis to accurately and repeatedly report back exact focal length and object distances. This means never losing steps and no drift over temperature.
