Ultra-Wide Day/Night No Distortion Lens - CS-mount DC Autoiris

Theia's SY110A series lenses provide ultra wide field of view without distortion. The lenses incorporate Theia's patented Linear Optical Technology which allows an ultra wide field of view without barrel distortion found in other wide angle lenses not including Theia's technology. This rectilinear design allows increased resolution at the edges of the image thus increasing the probability of detection in security systems. The rectilinear design also eliminates the dewarping software requirement for many machine vision applications, improving MV system performance.

Similar to Theia's other lenses, the SY110 series 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 SY110A 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.
