These zinc selenide (ZnSe) discs are precision optical parts with 99.99% purity, a 20mm diameter and a 3mm thickness, polished on both sides. They are made from zinc selenide produced by chemical vapor deposition, a compound semiconductor known for its optical performance.
ZnSe transmits light across a wide range, from the visible region through to the far infrared, which makes it a common choice for infrared optical work. The polished discs can serve as windows, lenses or other optical elements.
The material combines a low absorption coefficient with high resistance to thermal shock. These properties matter in setups that involve high power densities or rapid changes in temperature, such as laser systems.
- Windows, lenses and other optical elements in infrared optics.
- Optical components in laser systems with high power densities.
- Optical parts for medical instruments.
