Fiber Options

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:

 

Differential measurements of two targets with external reference.

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).

Environmental Compatibility

 

Several sensor heads are available for different environments such as ambient air, ultra-high vacuum, cryogenic or hard radiation.
