American Dynamics selected Theia's SL940A 9 to 40mm, 5 megapixel, IR corrected lens as their telephoto offering with their Illustra 600/610 indoor/outdoor mini-dome cameras.

* The lens provides a unique combination of features in an unusually small package.
* With a 9 – 40mm focal range the lens offers a powerful optical zoom for high detail images far away and full 5 megapixel resolution for crisp detail in a compact 50mm length which fits perfectly in the Illustra's sleek mini-dome envelope.
* The SL183 lens employs Theia's award winning Linear Optical Technology to provide up to 117 degrees of undistorted horizontal field of view (HFOV) on the camera's sensor, enabling coverage of more area with a single camera, potentially reducing the overall cost of HD and IP system ownership. The SL183A is also only 50mm long.
