Sapphire crystal is a transparent crystal without absorption from the visible to infrared wavelength of 5μm. In addition, sapphire has extremely hard and resists scratching.

◦Sapphire crystal is a very stable material used in optical equipment in the field.
◦Since there is no absorption (1.4μm, 2.2μm, 2.7μm) by water (OH radical), it can be used on a lens for the analyzer for near-infrared.

Guide

▶Sapphire jewelry is the thing that metal ions such as iron and titanium are mixed with natural sapphire crystal. The artificial sapphire crystal is colorless and transparent. It is available for the AR coating to reduce the transmission loss at the requested wavelength.
▶It can be used safely because it is harmless to the human body.

Attention

▶Transmissions losses due to reflection off the front and rear surfaces can be minimized by coating the surfaces. Consult our Sales Division for anti-reflection coatings suitable for your application.

Reference

▶Sapphire known as jewelry, is what metal ions such as iron and titanium mixed natural sapphire crystal. Artificial sapphire crystal is colorless and transparent.
