Quality Control

Every optic Crystran supplies goes through inspection to ensure compliance with specification. All goods and raw material coming into the company are also assessed to ensure they are of good quality and correct.

Investing in new inspection equipment and learning the latest techniques means that Crystran can constantly push forward the boundaries of what we can test, this in turn drives forward our production capabilities in being able to offer even higher specification optics.

Amongst our ever increasing range of cutting-edge test equipment, we have now upgraded our Spectrophotometers with brand new instruments. It is important for an optical shop like Crystran, who specialise in UV and IR optics, to be able to characterise our materials in these wavebands.
