IDSH/D4/F17/RAD
Ø 4 mm, length 11.5 mm
With its small size, the D4/F17 sensor head is applicable to space-confined applications. Despite the focusing optics, the sensor head can be used for longer working ranges, e.g. 60 mm on mirrors. It is also compatible to low reflecitve targets, like glass or polished steel.
The sensor head is designed for temperatures between 0..150 °C and radiation harsh environments. The sensor kit package includes two glass fibers. A radiation compatible glass fiber (length: 2m) connecting the sensor head to an optical feedthrough, and an ambient glass fiber (length: 5 m) connecting the feedthrough to the interferometer controller.
