PRODUCTS TC-04 CRYORAD CONTROLLER

L-1 is pleased to offer the new TC-04 radiometer electronics, a significant upgrade of the existing TC-02 electronics. This new system increases power resolution from 10 pW to 100 fW with a proportional decrease in measurement noise. All electronic boards and key components are temperature controlled to better than 0.1 K. The uncertainty of the power measurement scale is <10 ppm from 25 mW to 1 μW. The TC-04 electronics also include a number of software enhancements and measurement options that significantly impact measurement quality and user effort. The TC-04 incorporates a feed-forward control algorithm in the heater servos which significantly reduces the measurement time, allowing more measurements to be performed in a shorter time. The graphs below illustrate the advantages of using feed forward techniques.

Reduced measurement time is especially important when covering many wavelengths with a monochromator or tunable laser. The TC-04 system includes user inputs and outputs allowing synchronization of external equipment such as shutters and detector motions. The communication interface is 100-MBaud Ethernet.
