Silicon Sensors

UDT Instruments offers a wide range of silicon sensors for radiometric testing applications. UDTi photosensors and sensor heads are offered in three different mechanical configurations: Sensors from the Standard Series adapt for use with most accessories. The Miniature Series includes a similar range of sensors with a smaller-diameter package, compatible with UDTi’s line of integrating sphere accessories. The Low-Profile Series is designed for applications with limited mechanical clearance.
