Theia Technologies MCR500 Development Board for Controlling 4K Motorized Zoom & Focus with P-Iris Lenses (models supported: TL1250P-R3, TL1250P-R5, TL936P-R3, TL936P-R5, TL410P-R3, TL410P-R5, and ML410P-R5

For ease of evaluating Theia’s motorized lenses Theia offers a motor control board. This board allows the user to control zoom, focus, P-iris, and IR cut filters (there is no control for DC autoiris lenses). For evaluation, we offer a Windows based test program to communicate over USB. You may also communicate over i2c or UART from within your own program. Details are covered in the instruction manual from the link below, as well as CAD model and drawing of the board.

The board is intended to be used as an evaluation board in industrial and laboratory settings. Any use in a production environment will require the customer (you) to fully evaluate the functionality, lifetime, environmental, and other specifications and to apply and obtain necessary certifications. The evaluation software is provided as is and without warranty.  Any software we published (source or compiled) that is intended to control the motor controller boards from other hardware (i.e. PC, Raspberry Pi) is given for demonstration purposes only with no usefulness or functionality expected or implied. You are free to use it as they see fit - free of charge - but by such use you are accepting full responsibility for any consequences of such use, including but not limited to any financial obligations.

Motorized Lens Disclosure:


Please be aware that our motorized lenses are intended for integration into cameras and require motor drivers and controllers.  Typically Theia works with the camera manufacturer to ensure that the camera motor controller matches the lens.  We are worried that you or your customer may not know how to operate these lenses.   


It is possible for you or your customer to supply your own motor controller, but Theia cannot guarantee that your motor controller will not damage the lens.   Theia does not offer any warranty on the suitability of these motorized lenses for any particular camera.  For example, the connectors are not common for all cameras and may not work for yours.  These motorized lenses are not intended for continuous use of the motors as in PTZ applications.


Theia motors are step tested over the full zoom and focus range to be within an acceptable tolerance.  Theia cannot guarantee that zoom or focus set by the user can be mapped to a particular step within the range.  


Theia now offers motor control boards that are suitable to control only P-iris lens versions (see the lens specification for the relevant models).
