Armored Fiber Optic Cables
The sensor heads are connected to the controller by optical glass fibers. In addition to our standard polymere fiber tubings we offer a robust metal shielding (see picture) or PTFE for UHV.
The standard fiber lengths are 1.5 m and 3.0 m. Other lengths on request.

Sensor Head Options
PICOSCALE Sensor Heads allow several customizations to account for non-standard measurement tasks or limited installation space. Options include:
Beam Splitter Cubes
For C01 sensor heads different beam splitter cubes are available:
- Standard: The reference mirror is directly coated to the side surface.
- Front reference: The reference mirror is coated to the front surface so that the measurement beam exits perpendicularly.
- External reference: Without coating, differential displacement measurements become possible (see picture).
Several sensor heads are available for different environments such as ambient air, ultra-high vacuum, cryogenic or hard radiation.
