Concave Mirrors

Name: Concave Mirrors
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

Concave mirror is reflection imaging, not light through, no color difference, there are still spherical aberrations. If you need a mirror without spherical aberration, you can choose a paraboloid, ellipsoid, hyperboloid mirror. The concave mirror can be milling, fine grinding, grinding and polishing by CNC precision machining machine. Under the condition of precise control of the machine tool and processing environment, ultra-high precision machining in parabolic plastic field can be achieved, and the reflective mirror can be directly processed to meet the optical quality requirements, with the surface shape accuracy ≤0.1 micron. Surface roughness Ra≤0.01 micron.

Features of Concave Mirrors

One-stop customized production: Solar Valley processes a variety of circular, D-type, square, trapezoidal structure of concave mirror according to customer requirements. Concave can be paraboloid, ellipsoid, hyperboloid mirror.
Material: The base material uses optical glass, quartz, aluminum alloy, various metals and other materials, according to customer requirements.
Concave mirror performance: Concave mirror is reflective imaging, not light through, no color difference, there is still spherical aberration. If you need a mirror without spherical aberration, you can choose a paraboloid, ellipsoid, hyperboloid mirror. Concave mirror metal coatings have low peak reflectance, mechanical durability and damage threshold, with extremely high broadband and low cost, coated optical mirrors mainly include metal (aluminum, silver, gold) coatings and dielectric coatings. The concave mirror is coated and can be used in the visible and near infrared regions. Concave mirrors are commonly used in reflecting telescopes, electron microscopes, and a range of scientific instruments that need to image distant objects, and are widely used in laser systems, scanning systems, and optical measurement systems.
