The chemically inert nature, broadband transparency, low absorption coefficient and highest-known thermal conductivity makes CVD diamond ideal for as optical components in high-power lasers and attenuated total reflectance (ATR) spectroscopy. Polycrystalline diamond has potential as a transmissive material for electromagnetic radiation. Applications include protective or antireflection coatings on optical parts, X-ray windows and X-ray lithography masks. Further possibilities of using diamond in optical applications include the detection and measurement of optical radiation (low, medium, and high intensity far ultraviolet (< 225 nm) and near ultraviolet and visible light from dye or argon lasers).


The exceptional properties that transform the component performance of our Single Crystalline’s Super-hard material :

  • Low absorption coefficient
  • Upto 2200 W/mK thermal conductivity, the highest of any material at normal room temperature
  • They are the hardest materials known to science, being chemical and scratch resistant
  • It gives the widest transmission spectrum from 220 nm to >50 µm
  • It operates in corrosive environments and is chemically inert
  • Low birefringence is possible with Δn < 2 E -6

Heyaru’s single crystalline Super-Hard Material Optics components can be developed for any specific application and in virtually any shape:
