Theia Technologies

Theia offers many lenses from fisheye to ultra wide to telephoto. Below are the Theia Lens Categories:

4K resolution lenses and 4K camera compatible lenses support the new highest resolution cameras. These lenses are designed for use with 1/2.3″, 1/1.7″, and up to 2/3” image sensors.

Ultra wide angle lenses use Theia’s patented Linear Optical Technology® to correct barrel distortion in the lens without the need for additional software to dewarp the image. These lenses can provide horizontal field of view up to 135° without barrel distortion.

Mid focal range lenses fit the bulk of security and machine vision applications with their not-too-wide not-too-telephoto field of view.

Telephoto lenses offer a long focal length and long reach but are compact for use in small enclosures. They are day/night corrected for use with IR illumination.

Motorized lenses include motors for remote focus and zoom, IR cut module, and limit switches for focus and zoom. These compact lenses are designed for 4K resolution dome and bullet style cameras.

Fisheye lenses are designed for 360 cameras so they will present a full circular image that must be dewarped in the camera or server. These lenses are designed for applications where one camera in the center of the room is appropriate.

The 6-10mm varifocal lens covers focal lengths of 3 prime lenses – a 6mm, 8mm and 10mm. This provides the flexibility to dial in the focal length and field of view as needed for the specific application, making a modular, multi-product inspection line possible. Applications for this focal length range are diverse including monitoring hallways and classrooms in schools, keeping track of people in lobbies and office spaces, monitoring large warehouses for theft and security. Mid focal range lenses are available in both non-motorized and motorized configurations with board mounts (D25) as well.

SL940 compact telephoto

Theia’s telephoto varifocal lenses allows the user to optimize the field of view to zoom in on an area of interest far away (during camera setup). These telephotos allow the user to optimize the field of view with 4X zoom capability and then digitally zoom in up to 16X while still maintaining better than SD image resolution. The lenses are IR corrected for use with true Day/Night cameras giving a bright image in both visible and artificial IR illumination. This IR correction will keep the image sharp in daylight, at night, and in between when there is a mix of visible and IR illumination without the need for a camera with automatic back focus adjustement (the lens will work great on cameras that support auto back focus adjstement and those true Day/Night cameras that do not).

SL1250 4K telephoto

Theia’s SL1250 lens is designed to be very compact to fit into small spaces such as 4″ domes. This lens is designed for use on the new 4K box cameras for security and machine vision applications such as long distance fence line monitoring, license plate recognition (LPR) and other long distance security applications. The SL1250 versions are available with motorized or manual iris and CS mount whereas the sister TL1250 versions include motorized zoom and focus, photo interrupter limit switches, and board mount options. Similar to Theia’s other lenses, the SL1250 series is a high quality lens designed to allow the installer to take full advantage of the high resolution of 4K, HD, and multi megapixel cameras. The lens can be used on cameras up to 12 megapixel resolution (true 4K) giving a crisp image from edge to edge.

SY110 Ultra wide value lens

MY110 Ultra wide C mount

Theia’s SY110 (CS mount) and MY110 (C mount) series lenses provide an ultra wide field of view at a value price point. These lenses use Theia’s patented Linear Optical Technology® which allows an ultra wide field of view with low barrel distortion unlike other wide angle lenses that do not include Theia’s technology.

The SY110 and MY110 lenses are designed to allow the installer to take full advantage of the high resolution of HD and multi megapixel cameras.
