Filter Mount Accessory

This filter mount can be added to the 410 series lenses to allow an external filter (such as band-pass or polarizing filter) to be added to the system. The filter mount works with lenses with 35mm front barrel diameter and is held in place with 3 sharp point set screws. It will accept filters with M55x0.75 threads. Filters are not provided by Theia Technologies.

  • SL410
  • TL410
  • ML410
  • ML610

Part FMT-3555-S: Modified high performance aluminum filter mount for use with lenses:

  • SL1250
  • TL1250 *

(*special care required when installing filters to prevent damage to the motors)

Motorized lens control board

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.
