The CS-Mount 1.67mm f/1.8 3 Mp Ultra-Wide Day/Night DC Auto Iris Lens from Theia Technologies is designed for use with CS-mount CCTV cameras with 1/4”, 1/3”, or 1/2.5” sensors. The lens offers up to 120° (with 1/2.5” sensor) horizontal field of view for maximum coverage of the surveillance premises. Linear Optical Technology corrects barrel distortion, ensuring images with clear edges and improved viewability and eliminating the need for de-warping software.

With an iris range of f/1.8 to close, this lens is suitable for surveillance in low-light as well as bright light conditions. In addition, this IR-corrected day/night lens captures clear images, eliminating focus shift and infrared bleed.
