Theia Technologies’ ultra wide low distortion lenses

By replacing 4 standard cameras with one megapixel camera using Theia's ultra wide lens, the user can save money on installation, cabling, DVR and NVR ports, and image storage. With the Theia lens, the entire wide image is continually recorded, even while the user digitally pans and zooms from area to area.

New technology

Theia Technologies has introduced the world’s first ultra wide rectilinear lens for the security and machine vision markets. This new lens technology allows the design of ultra wide angle lenses with fields of view of up to 135° while almost completely eliminating barrel image distortion.

Below is an example showing a parking lot from the top of a 4 story building. The user can see a building entrance directly below the camera at the same time as cars near the horizon of the parking lot.

All optical distortion correction

Distortion correction is achieved optically using Theia’s patented Linear Optical Technology. Barrel distortion (otherwise known as fisheye distortion) causes the image at the edges to be compressed and lost. The information is unrecoverable through software. Theia’s rectilinear lens increases the ease of detection and identification at the edges of the image by optical distortion correction. No Software is required!
Theia offers high resolution throughout the image
Unlike a fisheye lens which only illuminates about 2/3 of the image sensor (leaving 1/3 of the pixels dark), the image from Theia’s lens completely covers the image sensor.

Award winning technology

Award winner for Special Achievement in Innovation 2008
Theia’s ultra wide, no distortion lenses won the Security Industry Association’s (SIA’s) Special Achievement in Innovation award at the ISC West show in April 2008 and Security Sales and Integration (SSI) magazine’s Show Stealer award at ISC East in Sept. 2007.

Kevin Mayer, CTO of Lumenera says
"We have been looking for a lens to match the capabilities of Lumenera's new LE575 5MPix surveillance cameras. Theia's lens is perfect for digital pan-tilt-zoom. Theia's lenses provide a sharp image and cover a wide field of view with very low distortion, thus eliminating the need for image de-warping software as with fish-eye lenses, and helps to reduce the camera count. I was very impressed!"

Paul Bodell, CMO of IQinVision says
"IQinVision has evaluated hundreds of lenses for quality and compatibility with our IQeye megapixel network cameras and found Theia's wide angle lenses provide excellent resolution and picture quality. Using the IQeye with Theia's wide angle lens lets you replace mechanical PTZ units or cover a large area with just a few cameras. It's important to note that all wide angle lenses are NOT created equal-Theia offers best-in-class quality."
