Theia part of lens options for IndigoVision HD camera
Wilsonville, OR (USA)
Theia's patented Linear Optical Technology enables an image with less than 1% barrel distortion. By contrast, most wide angle lenses above 80° horizontal field of view produce an image with noticeable levels of barrel distortion, also known as fisheye distortion. Distortion in typical wide angle lenses compresses data at the edges of the image, causing a loss of information, which translates into degraded image resolution in those areas. Theia's technology doesn't compress or lose information, but instead maps the subject over more pixels providing improved image resolution at the image edge and increasing the chance of recognition of individuals and objects.
Theia's lenses correct barrel distortion in the optics of the lens without the use of de-warping software for a faster, real time solution. Image information lost due to the barrel distortion of typical wide angle lenses cannot be recovered even with the use of de-warping software.
The SY110 lens is IR corrected so it maintains its crisp, clear megapixel resolution image in IR illumination making it a perfect accessory for IndigoVision's day/night camera, with removable infrared-cut filter. Theia's ultra-wide angle lens with IndigoVision's HD IP cameras broaden the possibilities by further enhancing the high-definition images provided through IndigoVision's camera technology.
