L-1 Milestones

 

L-1 Standards and Technology, Inc. acquired the cryogenic radiometer line of Cambridge Research & Instrumentation, Inc. (CRI) in 2001. This product line includes the LaserRad-II, CryoRad (ACR), and the CryoRad-II primary standard electrical-substitution radiometers. CRI was a pioneer in commercializing the field of primary optical power measurements, giving laboratories around the world access to state-of-the-art instruments for use as national standards. L-1 continues to build these instruments, while introducing new versions with even lower noise, wider dynamic range, longer helium hold times and the option of mechanical cooling.

 

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.

 

L-1 has developed a range of support items for ambient calibration work such as trap detectors, ultra-precision, ultra-stable amplifiers and temperature controllers.

 

L-1 also produces cryogenic items such as blackbodies, mirrors, monochromators, mechanical motion, choppers, stepper motors, electronics, and detectors.
