According to Don Ashley, Product Manager at Iqinvision, “the ultra wide, undistorted images captured by Iqinvision’s megapixel security cameras with Theia’s SL183 lens made our decision to offer this lens to our customers easy. Theia’s SL183 is an ultra wide lens we can recommend without hesitation for use with the IQ700 and Sentinel Series megapixel cameras.”

The SL183 offers a powerful combination of true megapixel resolution and IR correction in a compact envelope of only 50mm long. The IR corrected lens maintains its crisp, clear megapixel resolution image in IR illumination making it a perfect for use with Iqinvision’s megapixel day/night security cameras, with removable infrared-cut filters. And the Easyzoom feature allows the user to optimise the field of view with minimal need for refocusing.

Both Theia and Iqinvision demonstrated the lens at the ISC West security exhibition in Las Vegas last week.

The new SL183 lens leverages Theia’s patented Linear Optical Technology platform to offer an ultra wide field of view without distortion in the flexibility of a varifocal model. The lens provides up to 115 degrees undistorted horizontal field of view (HFOV), providing the opportunity to cover more area with a single security camera, potentially reducing the overall cost of system ownership. The award winning technology uses all optical distortion correction to remove barrel distortion without the use of software. According to Theia, compared to typical wide angle lenses, Theia’s technology increases resolution at the edges of the image improving the ability to recognise subjects.
