Theia : TL410
Description
Theia’s new TL410 family of 1/1.7″ 4k lenses are true 12 megapixel resolution lenses.
Similar to Theia’s other lenses, the TL410 is a high quality lens designed to allow camera manufacturers and installers to take advantage of the new 4K cameras on the market. The lens can be used on cameras up to 12 megapixel resolution giving a crisp image from edge to edge. The lens can be used with 1/2.3″ 4K sensors such as Sony IMX172 up to 1/1.7″ 4K sensors such as Sony IMX226.
The lens is IR corrected for use with true Day/Night cameras. This IR correction focuses IR light from artificial illumination at the same plane as the visible light allowing the image to remain in focus when the Day/Night camera switches to night mode. Unlike lenses without IR correction, the night image will not be out of focus when using IR illumination.
