The Theia Technologies 1.8-3mm C-mount Day/Night lens range achieves a 4K resolution 120-92° horizontal angle of view on a 1/2.3” sensor using patented Linear Optical Technology®. They are available in Manual (ML183M) and DC-iris (ML183A) options and have an iris range from F1.8-Closed. These Theia lenses achieve an ultra-wide field of view with ULTRA LOW DISTORTION (<1% barrel), are suitable for camera sensors up to 1/2.3″ and designed for Machine Vision and FA applications where a wide angle low distortion image is required.
The Theia Technologies 1.8-3mm C-mount Day/Night lens range achieves a 4K resolution (4000 x 2000 pixels) 120-92° horizontal angle of view on a 1/2.3” sensor using patented Linear Optical Technology®. These C-mount lenses are available with Manual Iris (ML183M) or DC-iris (ML183A) and have an iris range from F1.8-Closed. They achieve an ultra-wide field of view with ULTRA LOW DISTORTION (<1% barrel) and are suitable for camera sensors up to 1/2.3″.
The superior quality of this lens combines stunning performance with the highest build quality and will support sensor technology up to 4K resolution. Being C-mount, the lens is designed for use in Machine Vision and FA applications where a wide angle low distortion image is requires. It is also ideal for a wide range of security, broadcast and industrial applications. We also recommend these for use with Back-Bone modified GoPro and SeeSense GEM cameras.
These lenses are also available in CS-mount Manual iris SL183M and CS-mount DC iris SL183A.
