Theia's Ultra wide lenses using Linear Optical Technology®

Theia's family of ultra wide angle lenses incorporates patented Linear Optical Technology® which allows an ultra wide field of view while optically correcting barrel distortion in the lens. No dewarping software is required. This optical distortion correction increases the image resolution at the image edges, thus improving the probability of detection and identification of individuals, especially at the image edges. All these lenses are multi megapixel resolution supporting cameras up to five megapixels with a sharp image from side to side.

Theia offers several families high quality megapixel lenses designed to high image resolution standards. The use of aspheric lens elements and extra low dispersion glass types (ELD-glass) enable the unique features of each of Theia's lens families, be it ultra wide angle or short telephoto. Theia's process of precision engineering and prototype development and validation assure every lens shipped to our customers will be consistently high quality. Choosing the right lens for your application depends on many factors including field of view, required image resolution, day/night capability, and cost. To assist in lens selection, Theia offers an image simulator/ lens calculator that relates FOV, resolution, and object distance. We also offer many educational materials for a better understanding of the technology and selection of Theia's optimal lens for your application.

All these lenses are also available in C-mount versions for machine vision applications.
