Sapphire Optics

Sapphire Optics and its components are widely used in different applications that need high durability as well as broad spectral ranges. It is employed in different products such as FLIR imaging, semiconductor, FTIR spectroscopy, etc. Sapphire is the second hardest crystal ideal to be used in the harshest environments owing to it properties of extreme surface hardness and high thermal conductivity. In addition to this, it comes with high dielectric constant, resistance to chemical acids or alkalis. Due to unmatched properties of sapphire, its optics is available with high-end features. It comes with thinner designs having the transmission ranges from 0.15 to 5.5μm. This is available in chemically inert design that stays totally unaffected even after using a range of chemicals. With high thermal conductivity, it ensures to stay stable at cryogenic temperatures.

Features of Sapphire Optics:

1) Optimum performance in the UV to the MWIR range.
2) High refractive indices that minimize the distance between lens as well as fiber output.
3) Simplify mounting as well as system integration.
4) Extreme surface hardness with highly resistant design to scratching and abrasion.
