Theia's family of Ultra wide field of view megapixel lenses use our patented Linear Optical Technology ? to optically correct barrel distortion without the use of de-warping software. The lenses provide the widest field of view available without distortion while keeping straight lines straight. The ultra wide field of view requires fewer cameras to cover large areas and provides greater situational awareness for the viewer.
---Theia's SL183 series of varifocal lenses includes EasyZoom ? which allows the installer to optimize the field of view with minimal need for refocus.
--- Theia's high quality lenses are compatible with cameras up to 4K resolution enabling the installer to take advantage of all the pixels megapixel cameras have to offer.
--- The -110 and -183 series lenses are IR corrected for use with true Day/Night cameras. Light from LED illuminators focuses to the same plane as visible light allowing the highest image quality at night without the need to refocus the camera.
--- The -125 series offers the widest field of view available, up to 135o, without barrel distortion. All lenses are designed for CS-mount or C-mount cameras with image sensor sizes 1/3”, 1/2.7” HD, and 1/2.5”. The -183 series is also compatible with 1/2.3” 4K format sensors.

Theia's telephoto lenses provides a combination of features rarely found in other lenses available on the market. Both series are high performance megapixel and 4K resolution lenses providing the sharpest image with maximum detail. They both feature compact size with excellent IR correction for use with Day/ Night cameras.

---Theia's telephoto lenses are IR corrected for use with true Day/Night cameras. IR and visible light will be focused to a common plane allowing the best image quality during day and night without the need to refocus the camera.
---The lenses support 4K resolution cameras with a crisp image from center to edge and throughout the optical zoom range.
--- The –940 and –1250 series lenses are some of the shortest megapixel lenses available at telephoto focal lengths. As a bonus, the lens is IR corrected, a feature rarely found in other telephoto megapixel lenses even those with longer physical length.
--- Designed for CS-mount cameras. The –940 series is compatible with 1/3”, 1/2.7” HD, 1/2.5” and1/2.3” 4K format sensors. The –1250 series includes 1/1.8”, and 1/1.7” 4K format sensors as well. Also available in motorized and board mount versions.

Theia's standard focal range lens includes true 4K (12MP) resolution, excellent IR correction for use with Day/Night cameras, and compact size for a very high performance lens. The small size allows the lens to be used in small enclosures such as dome & bullet cameras (with interchangeable lenses). The –410 series lenses have an easy to use focus adjustment ring for simple and precise focusing from 0.5m to infinity.
