The Theia Technologies C-Mount 1.68mm Day/Night Manual Iris Lens provides ultra wide field of view without distortion. The lens incorporates Theia's patented Linear Optical Technology, which allows an ultra wide field of view without barrel distortion. 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.
The lens is designed to allow you to take full advantage of the high resolution of HD and multi MP cameras. The lens can be used on cameras up to 3MP 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.
Ultra wide horizontal field of view up to 120° provides greater security
Linear Optical Technology enables no barrel distortion for maximum resolution
IR corrected for Day/Night cameras
Supports multi MP resolution cameras for demanding applications
Near and far objects continuously in focus without lens adjustment
