Rectilinear Lenses

Theia Techonologies range of ultra wide angle lenses incorporates patented Linear Optical Technology® that permits an ultra wide field of view whilst optically correcting barrel distortion in the lens.  This optical correction increases the image resolution at the edges and corners of the picture and remove the need for dewarping software.

These lenses are widely offered by SeeSense for Broadcast applications where a wide angle, low distortion and high resolution sharp image is desired.  In Security applications these lenses improve the probability of detection and identification of individuals, especially at the image edges.
