Optical Components Spectroscopy elements
Diamond ATR Units
For ATR spectroscopy, where light probes the sample at the diamond surface.
Good to know
- Single-reflection and multiple-reflection geometries offer different optical paths.
- Facet geometry controls how light enters, reflects and exits.
- The sample-contact face needs an appropriate finish and mounting arrangement.

Where it is used
- Lasers & PhotonicsOptics must transmit light and survive heat load; diamond transmits and conducts heat away.
- Semiconductor EquipmentProcessing demands precision, cleanliness and compatible materials; diamond parts are specified around all three.
- Research & QuantumExperiments need pure material and sensitive measurement; diamond is specified to your conditions.
