IDSH/M12/F40/LT/UHV/RAD
Ø 14 mm, length 19.5 mm
The focusing sensor head M12/F40 is used for standard applications, e.g. for measuring vibrations or material deformations. Because of the larger lense's diameter, it enables a quite high angular tolerance of ±0.35°. The housing is designed for high stability and the sensor head is capable of measuring on various applications.
The sensor head is designed for temperatures between mK..423 K, pressures down to 5 E-11 mbar and radiation harsh environments. The sensor kit package includes two glass fibers. A LT/UHV/RAD 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.
