Ultra Wide No Distortion Lenses

tHEIA-LOT-2

Overview

Theia Technologies’ ultra-wide no distortion lenses with patented Linear Optical Technology® correct barrel distortion optically, eliminating the need for software correction and its inherent latency. This enables true real-time imaging while preserving high resolution across the entire field of view, increasing resolution at the image edges compared to typical wide-angle lenses, and delivering ultra-wide coverage, even from close working distances. Ideal for AI vision, robotics, factory automation, and video surveillance applications, these lenses improve object detection, visual SLAM, 3D mapping, and autonomous navigation by maintaining straight lines in the image. Deployed in smart factories, AMRs, UAVs, and security systems, they deliver ultra-wide coverage, high-resolution, and undistorted imagery, enhancing situational awareness, inspection, and AI-driven analytics across industrial and security applications.

**In multi-spectral applications when different spectrum filters are required, Theia’s FMT-3555 fil&#8207ter mount acces&#8207sory can be used to attach optional filters. Theia’s FMT-3555 filter mount acces&#8207sory is compatible with SY110, MY110, and MY23F models. It is also possible to place a small filter between the rear of the lens and camera sensor on all lens models. Filters sold separately.
