Fiber Options

PICOSCALE sensor head with steel armored fiber.

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:

 

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.
