Linear Optical Technology
Theia Technologies in partnership with Nittoh Kogaku
as designed ultra wide angle lenses using patented 
Linear Optical Technology. The lens enables the viewer to take full advantage of the high resolution
of today's CCTV megapixel security cameras. With "More image - More security",
Theia's lenses offer ultra wide fields of view of up to 135 degrees while maintaining very low
distortion. Distortion correction is accomplished optically in the lens giving a crisp image from
image center to edge.

Megapixel class resolution
Theia's lenses in combination with today's megapixel cameras and IP cameras enhances electronic PTZ functionality
by increasing the field of view while requiring fewer cameras to monitor a scene. Monitoring high value assets such
as electrical substations (as seen below) typically requires two cameras in a corner. Theia's lens captures
more than 90 degrees horizontal field of view allowing fewer cameras to be installed and reducing the cost
of installation. Our lenses have a field view of up to 135 degrees while maintaining very low distortion.

Optical distortion correction
Because distortion correction is done in the lens optically, no additional dewarping software or hardware is
required. Images appear more natural and have greater resolution compared to lenses with barrel distortion such
as fisheye lenses. With a fisheye lens, not only are there unilluminated pixels on the sensor (illuminating only
about 2/3 of a 3 megapixel sensor) but the image gets compressed at the edges. Theia's rectilinear lens actually
increases the object size closer to the image edges.
