IDSH/M15.5/F40/FLEX/LT/HV
Ø 22 mm, length 22.7 mm
With the same optics like the M12/F40, the sensor head M15.5/F40/FLEX can also be used for measuring vibrations or material deformations on various surfaces. It is additionally equipped with a flexible structure for an easier alignment of the sensor head: the head can be tilted with a range of 1°.
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.
