Theia Technologies’ IQ Lens™ System brings together a motorized lens, motor control board, average calibration data, and software with graphical user interface (GUI) to form a modular, highly configurable system. Until recently, the user needed to develop their own motor control software. Theia’s IQ Lens™ System software application and intuitive graphical user interface saves the user considerable development effort and cost, speeding time to market.

The IQ Lens™ calibration data provides intelligence that enables optimal image quality and easy imaging system setup. The compact, lightweight varifocal lens and motor control board provide for remote operation in hard to reach or mobile environments. Combined, these elements allow for convenient and cost-effective integration into the imaging system.

Theia's telephoto varifocal lenses allow the user to optimize the field of view to zoom in on an area of interest far away (during camera setup). The multi megapixel resolution lenses support the new 4K resolution cameras with 4K compatible lenses and true 4K resolution (12 megapixels) lenses for 1/2.3" and 1/1.7" sensors.

These telephotos allow the user to optimize the field of view with 4X zoom capability and then digitally zoom in up to 16X while still maintaining better than SD image resolution. The lenses are IR corrected for use with true Day/Night cameras giving a bright image in both visible and artificial IR illumination. This IR correction will keep the image sharp in daylight, at night, and in between when there is a mix of visible and IR illumination without the need for a camera with automatic back focus adjustment (the lens will work great on cameras that support auto back focus adjustment and those true Day/Night cameras that do not).

Theia offers a downloadable Motor Temperature Calculator that estimates the temperature of focus and zoom motors after cycles of running and cool down.

For ease of evaluation of Theia’s motorized lenses we offer a lens motor control board. This can be controlled by USB, I2C, and UART connections. You will find more information about the Motor Control Board at the link shown.

Theia's TL1250 lens is designed to be very compact and better image performance compared to competitive products.  Despite the long focal telephoto focal length, this lens is designed for small 4" dome cameras and bullet cameras.  

Similar to Theia's other lenses, the TL1250 series is a high quality lens designed to allow the installer to take full advantage of the high resolution of 4K resolution, HD, and multi megapixel cameras.  The lens can be used on cameras up to 12 megapixel resolution giving a crisp image from edge to edge.
