Diamond has a variety of extraordinary properties and is an ideal material to meet the requirements of optical applications. It has the highest 

thermal conductivity to date and exhibits the broadest spectral transmission range, covering the ultraviolet, visible, infrared, terahertz and 

microwave spectral ranges.

●Ultra-wide transmission bandwidth: can transmit from 220nm to >50μm

●Ultra-high thermal conductivity: >2200W/mK, 100 times that of sapphire. It brings continuous and stable output of higher power, 

eliminating the need for frequent replacement windows and reducing maintenance costs.

●Corrosion resistance, high hardness, good X-ray transmittance and biocompatibility

●Application areas: high-power CO2 lasers, high-power solid-state lasers, spectroscopy, semiconductors (UV lithography), terahertz and 

radar, aerospace and defense.
