Integrating Spheres for UV


Instrument Systems offers complete measurement solutions for UV-A, -B and -C radiation starting from 200 nm. The operation of the well-proven Instrument Systems spectroradiometers, e.g. CAS series, with integrating spheres made from PTFE facilitate high sensitivity measurements of UV radiant flux.

All Instrument Systems UV measurement solutions with PTFE integrating spheres are delivered with a PTB traceable calibration.
