Optical Components Optical sample cells
Diamond Liquid Cells
Holds a liquid in a defined optical path for spectroscopy.

Good to know
- Window spacing sets the liquid path length.
- Seals and the cell body must be compatible with the sample.
- Window transmission and cell geometry must suit the measurement band.

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.
