Product description Theia Technologies' 1.28mm F1.8 M/I 2.5", 1/3" IR-Transmitting C-Mount Lens has a fixed 1.28mm focal length and F1.8 aperture that capture images in an ultra-wide 135° field of view with less than 3% barrel distortion. This lens is designed for C-mount cameras with image resolutions up to 5MP, and its durable metal construction and anti-vibration locking screws make it ideal for machine vision applications in demanding environments. Furthermore, built-in IR-transmitting optics allow this lens to be paired with IR illuminators with a transmittance up to 950 manometers within the infrared spectrum. In addition to these features, this lens uses Theia's patented Linear Optical technology that correct barrel distortion optically, and thereby eliminating the need for developing a custom dewarping/image stitching algorithm that's generally needed with wide-angle lenses. - Patented Linear Optical Technology
- Unlike many fisheye lenses that suffer from image degradation for objects not immediately to the center of the lens, this Theia lens, through the use of patented optical technology, is able to maintain superb image sharpness even for objects situated around its edges. Its use of pan-focus technology also means that near and far objects will remain in focus without the need for a user to make manual adjustments. This lens can be used with both standard and multi-megapixel CCTV cameras.
