Theia 1.8-3mm F1.8 CS DC iris

High-Resolution Ultra-Wide Performance

The Theia 1.8-3mm SL183/ML183 series is engineered for high-definition surveillance, supporting resolutions up to 5 megapixels. Utilizing patented Linear Optical Technology®, this lens provides an ultra-wide field of view up to 116° without the barrel or fisheye distortion common in standard wide-angle lenses. This ensures crisp, edge-to-edge image clarity for demanding security applications.

Simplified Installation with EasyZoom™

Setting up your field of view is faster than ever. The integrated EasyZoom™ technology allows installers to set the focus once and then adjust the zoom or magnification. Unlike traditional varifocal lenses that require repetitive focus-zoom-focus adjustments, this lens requires only minimal optimization after zooming, significantly reducing installation time.

True Day/Night IR Correction

Designed for 24/7 operation, the lens is IR corrected for use with multi-spectral and Day/Night cameras. By focusing infrared and visible light on the same plane, it prevents focus shift when switching to night mode. This ensures your security footage remains sharp and usable even under artificial IR illumination.
