High-Quality CO2 Laser Reflecting Mirror from China Suppliers - Durable & Efficient Factory Direct Price
Material characteristics
The base material of the reflective mirror is silicon, copper, Mo. The silicon is the normal coating material and it has the advantage of low cost, strong durability and stable thermal properties. The copper is usually used in the high power CO2 laser owing to it's high thermal conductivity. The Mo can be used in a poor condition owing to it's high surface strength and it can bear high power without surface coating, with long life span.
Principle
The reflective mirror is usually used as the end mirror or the folding reflective mirror in the laser cavity during the light transmission, while it's be acted as the role of the beam turn-back mirror outside the laser cavity. A CO2 laser mirror is a key optical component used in CO2 laser systems, which typically operate at a wavelength of 10.6 microns in the infrared spectrum. These mirrors are designed to reflect the high-power infrared laser beam with minimal loss and distortion.
Use
CO2 laser mirrors are essential components in various industrial and scientific applications. They are primarily used in CO2 laser systems for tasks such as laser cutting, engraving, and marking, especially in materials like wood, plastics, metal, and glass. These mirrors help direct and focus the laser beam accurately, ensuring high precision and efficiency in the laser processes. CO2 laser mirrors are also used in research and development, including spectroscopy and medical applications like laser surgery, where precise beam delivery is critical. Their ability to handle high-power infrared laser beams while maintaining minimal distortion makes them indispensable in fields requiring advanced laser technology.
