Diamond optics have gained acceptance in a wide variety of applications due to its unique optical and thermal properties:
- Except for an intrinsic absorption band at ~5 um, un-coated diamond has a relatively constant absorption of about 30% from visible wavelengths to microwave frequencies. Also, diamond’s refractive index varies little in this very wide spectral range.
- With this low absorption, an unequaled thermal conductivity, and very small thermal expansion coefficient, distortion of transmitted beams due to thermal lensing is minimized.
- Diamond’s hardness and chemical inertness make instrumentation applications in harsh environments practical.
