IDSH/M12/F40/LT/HV
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 and pressures down to 1 E-8 mbar. The sensor kit package includes two glass fibers. A LT/HV 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.
