Robust... Versatile...
Simple...
The Two Position Zoom Lens is simple to use. Just set the lens to the broad field-of-view position for easy aiming and focusing, then rotate the lens into the zoom position. The area of interest will remain in focus but will be magnified 5X.
Anodized aluminum construction
The bayonet mount attaches easily to a wide variety of infrared cameras, including Stress Photonics' DeltaTherm and Raytheon's RADIANCE line of cameras.
