Overview
Vacuum low-temperature blackbody radiation source
Product Details
RussiaVNIIOFIThe vacuum low-temperature blackbody radiation source series was developed by the All Russian Institute of Optical Physics Measurement, a technical control and metrology department of the Russian Federation. At present, it has been applied in multiple national metrology institutes and has received widespread praise from users.
The vacuum low-temperature blackbody radiation source series has high stability and a wide range of models, with temperatures as low as 80K. For specific models, please contact York Company.
