Sensor Head M15.5/F40/FLEX
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 kit package for ambient conditions includes a glass fiber (length: 5 m) for connecting the sensor head to the interferometer controller. Depending on the environmental option chosen, an additional fiber for connecting the sensor head in-situ is also included (/LT/HV, /RAD, /UHV).
