Product Description

CVD single crystal diamond properties:

Diamond has the widest transmission spectrum among all solid materials available, ranging from 225nm in the ultraviolet to 25 μm in the infrared (except for wavelengths of 1.8μm-2.5μm), as well as excellent transmission in the microwave range. Due to its excellent optical properties, strong resistance to radiation damage, strong hardness, high thermal conductivity, high chemical stability, and low coefficient of expansion, diamond is an ideal material for the production of modern infrared optical windows.

Application:

High power CO₂ lasers

Long wavelength IR imaging (8-14 micron)

Spectroscopy

High power RF generators and gyrotrons

Disc lasers

Raman lasers

Diamond lenses

Diamond has an exceptionally high transmission over a very broad range of wavelengths and low scatter in IR applications. It is extremely hard and chemically inert; making CVD diamond the optimal choice in applications demanding higher power, larger area, and resistance to hazardous materials or greater strength. These abilities also enable smaller material geometries to be used, which opens up new lightweight applications. Advances in the creation and shaping of diamond enable us to provide solutions to novel optical problems.

Key product features:

1. The refractive index of diamond should be ~2.4. We need to achieve broad and high transmission in the mid-infrared at wavelengths from 1 micron to 30 microns.
2. The surface roughness should be well below 50nm for good transmission from 1μm wavelength,
3. The error should not exceed 0.2mm,
4. Applied to infrared radiation measuring device, the triangular diamond prism is good for mid-infrared transmission.
