Theia Technologies SL940M 1/2.5" 9-40mm F1.5 Manual Iris Vari-Focal CS-Mount Lens, 5 Megapixel Rated, IR Corrected (Day/Night)
Focal Length: 9.0-40.0mm
Iris Type: Manual Iris
5 Megapixel Rated; IR Corrected (Day/Night); M.O.D. 2.5m.
Note: Due to the type of distortion correction technology used for Theia lenses, the initial image output will be inverted. This is corrected by either doing an image flip through the camera software or by physically inverting the camera.
Theia's SL940 with it's long focal length magnifies objects from far away for unobtrusive security. Similar to Theia's other lenses, the SL940 is a high quality lens designed to allow the installer to take full advantage of the high resolution of HD and multi megapixel cameras. The lens can be used on cameras up to five megapixel resolution giving a crisp image from edge to edge.
The lens is IR corrected for use with true Day/Night cameras. This IR correction focuses IR light from artificial illumination at the same plane as the visible light allowing the image to remain in focus when the Day/Night camera switches to night mode. Unlike lenses without IR correction, the night image will not be out of focus when using IR illumination.
