Photonchina supplies a wide variety of mirrors, ranging from laser line mirrors, harmonic separator mirrors, high reflection (HR) mirrors, partial reflection mirrors and metallic coated mirrors. Wide selection of rectangular, round, elliptical, or custom shape mirrors with flat, spherical concave or convex and cylindrical surfaces can all be produced.
HR laser line Mirrors (HR Mirrors)
HR laser line mirrors (HR) provide optimized performance at certain wavelength and certain angle of incidence (AOI). Mirror consists of substrate and multilayer coating stacks which help to achieve very high reflectivity at specific laser line wavelength at any designed angle of incidence. Laser line HR coatings are used for external beam manipulation applications where even slight losses may be intolerable. Coatings are provided by electron beam evaporation with/without ion assistance coating technique.
HR Broad Band Mirrors (BBHR Mirrors)
HR broad band mirrors (BBHR) provide high reflectance for a broad spectrum.
These multilayer coatings offers high reflectivity for broad spectrum. Therefore, it is the ideal for a wide range of multi-wavelength laser or white light applications.
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques.
HR dielectric coatings are available in the range of 0.19 - 20 μm..
Metallic Coated Mirrors(MC Mirrors)
Metallic mirrors and partial reflectors
Photonchina has long been offering gold, silver, aluminum, chrome and copper metallic high reflection and partial reflection coated mirrors for customers home and abroad.
Photonchina metallic coated mirrors features:
Protected Gold provides excellent, broadband infrared high reflectance
Protected Silver provides higher reflectance than aluminum throughout the visible and near IR
Protected Aluminum is economical solution for VIS applications
UV enhanced Aluminum provides good reflectance over a wide range and are mainly used in UV applications.
