Theia Technologies provides high quality 4k and megapixel lenses security and machine vision applications. Their patented, award winning Linear Optical Technology® corrects barrel distortion and improves image resolution over typical lenses, while also eliminating the “fisheye” effect. Theia offers many lenses from fisheye to ultra wide to telephoto.

Description

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.

Theia’s family of ultra wide angle lenses incorporates patented Linear Optical Technology® which allows an ultra wide field of view while optically correcting barrel distortion in the lens. No dewarping software is required. This optical distortion correction increases the image resolution at the image edges, thus improving the probability of detection and identification of individuals, especially at the image edges.

ultra-wide-angle-lenses

Theia’s SL183 (CS mount) and ML183 (C mount) lenses provide ultra wide field of view without distortion. These are varifocal lenses allowing the user to optimize the field of view from wide angle to ultra wide. The lenses incorporate patented Linear Optical Technology® which allows an ultra wide field of view without barrel distortion unlike other wide angle lenses not including Theia’s technology. This rectilinear design allows increased resolution at the edges of the image thus increasing the probability of detection.

The focal length range of Theia’s mid range lenses covers the majority of applications for security and surveillance. These lenses are designed to be very high quality, compact lenses for use in domes and bullet cameras. 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.

sl410-lens-at-4mm-focal-length

Theia’s SL410/ML410 lens is designed to be very compact and better image performance compared to competitive products. This lens is designed for use on some of the new 4K box cameras for security and machine vision applications.

Focal length: 6-10mm varifocal
4K (12MP) resolution
1/2.3″, 1/1.7″, up to 2/3” sensor sizes

Theia’s ML610M is a 12 megapixel resolution, varifocal lens with 6-10mm focal range providing from 51 degrees up to 87 degrees horizontal field of view on the 2/3″ sensor. 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

Focal length: 9-40mm varifocal
5+ MP resolution
1/2.3″ 4k camera compatible
F/1.5

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).

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.

sy110-ultra-wide-value-lens-1

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. The lens can be used on cameras up to three megapixel resolution giving a crisp image from edge to edge. 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.

 TY180IR Fisheye

360° fisheye
1/2.3″ sensor size
4K resolution (12MP)

The fisheye lens is also available in day only version if there is no day/night cut module in the camera. The day only version includes an IR blocking filter in the lens. This version is TY180F. 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.
