Sensor Head M12/F40

Sensor Head M12/F40

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 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).
