High Quality Copper Mirror for Optical Processing

High Quality Copper Mirror for Optical Processing

Product Description

Copper mirror is a special optical component, mainly used in laser technology, and its base material is copper or copper alloy. The copper mirror reflects the laser beam through its highly reflective surface to guide, focus, or change the direction of the laser beam. Because of its high thermal conductivity, good mechanical properties and corrosion resistance, copper has a unique application advantage in laser systems.

Material

Base material: The base of the copper mirror is usually made of oxygen-free copper or copper alloy, which not only has good thermal conductivity, but also can withstand the irradiation of high-power laser beam without damage.

Coated: In order to improve the reflectivity, the surface of the copper mirror is usually plated with one or more layers of dielectric film or metal film (such as silver, aluminum, gold, etc.). The coated copper mirror enables high reflectivity over a wider wavelength range and has better durability and stability.

Advantages

01

High Thermal Conductivity

The high thermal conductivity of the copper material enables the copper mirror to dissipate heat rapidly in the high-power laser system, keep the temperature of the mirror stable, and avoid performance degradation or damage caused by high temperature.

02

High Reflectivity

By coating treatment, the laser copper mirror can achieve nearly 100% reflectivity, effectively reducing the energy loss of the laser beam during transmission.

03

Corrosion Resistance

The copper material itself has a certain corrosion resistance, which can resist the erosion of environmental factors to a certain extent and extend the service life of the mirror.

Copper mirrors are divided into parabolic copper mirrors and flat copper mirrors, which are different in form and function. The reflecting surface of the parabolic copper mirror is a paraboloid, that is, a reflecting device made of the shape formed by the rotation of the parabola, and the reflecting surface of the flat copper mirror is a plane, that is, the mirror is flat, without concave and convex.

Parabolic Copper Mirror

Based on its geometric characteristics, parabolic copper mirrors can focus parallel incident laser beams to the focal point to form high energy density spots. This feature is particularly important in laser processing, laser cutting, laser welding and other applications, which can achieve accurate machining and efficient processing of the workpiece. At the same time, the parabolic copper mirror can also convert the laser emitted by the point source into a parallel beam, which has a wide range of applications in laser transmission and collimation systems. In high power laser systems, parabolic copper mirrors are commonly used in optical resonators, beam conversion and focusing systems. Due to its excellent focusing performance and thermal stability, parabolic copper mirrors can withstand high power laser irradiation to ensure the stable operation of the system.

Flat Copper Mirror

Flat copper mirrors are mainly used to reflect and guide laser beams in laser systems. By adjusting the angle and position of the flat copper mirror, the propagation direction of the laser beam can be changed, and the precise control and positioning of the laser beam can be realized. Flat copper mirrors are widely used in some low power laser systems because of their simplicity and low cost. These systems may include applications such as laser marking, laser ranging, and laser scanning. In some specific conditions, such as the need for a large area of uniform irradiation or the need to adjust the polarization state of the laser beam, the flat copper mirror can also play its unique role. By combining with other optical elements, complex laser beam control and transformation can be achieved.
