Save Money with Theia Lenses

Wider Angle -> No Distortion -> Fewer Cameras -> Lower Cost

Today’s megapixel cameras have many advantages as long as you have the right lens for the job. When that includes covering large areas or reducing cost by installing fewer cameras, that lens is a wide angle lens. Until recently only fisheye lenses were available for an ultra wide field of view. Fisheye lenses create a curved and distorted image which no one seems to like. This significant distortion causes loss of resolution at the image edges.

In the past year a new rectilinear lens giving a different ultra wide view without the barrel distortion or loss of edge resolution of fisheye lenses has been developed.

New Technology

Theia Technologies has introduced the world’s first ultra wide rectilinear lens for the security and machine vision markets. Theia’s proprietary Linear Optical Technology allows the design of ultra wide angle lenses with fields of view of panoramic proportions, up to 135° while almost completely eliminating barrel image distortion.

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.

135° Field of View, No Fisheye Distortion

Distortion correction is achieved optically using Theia’s patented Linear Optical Technology.  Barrel distortion (also known as fisheye distortion) causes information at the edges of the image 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 using optical distortion correction.  No special software is required!

Award winning technology

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 September 2007.
