We are a leading producer of a range of optical crystal materials for infrared, FTIR and ultraviolet window applications. Infrared window crystals include Sodium Chloride (NaCl), Potassium Bromide (KBr), Potassium Chloride (KCl), Caesium Iodide (CsI) etc.

These are primarily used for windows and beam splitters in infrared spectroscopy and can be supplied from 2mm to 300mm in size. These optical crystal materials can be supplied either as sawn optical blanks, fine ground optical blanks or with a pre-polished finish.

Applications range from pharmaceutical quality assurance to space applications. Hilger Crystals flexibility in manufacturing techniques ensure that a rapid quality service can be assured.

All grown ingots are tested for infrared absorption and scatter.
