NightcrawlIR MWIR Lens Assemblies
Utilizing unique aperture specific fore optics and a modular base to maximize performance, Nightcrawlir lenses are purpose-built from the ground up for the demands of high resolution applications.
Full Product DescriptionProduct description
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.
