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.
Photonchina HR mirrors features

- Coatings are provided by ion beam sputtering (IBS) or electron beam evaporation with/without ion assistance coating techniques
- HR laser line coatings (HR) highly reflect wavelength range of <10% of the central wavelength (CWL). For instance, HR @ 800 nm will reflect wavelength range of 760-840 nm
- Various dimensions are available on request
- Mass production capabilities: 5000 pieces per month
- Custom coatings are available for any wavelength in a range of 0.19 – 20 μm

Ultra-Broadband Dielectric Mirrors(UBD Mirrors)
Ultra-Broadband Dielectric Mirrors high reflect in the range 350 – 1100 nm, AOI – (0°-50°).
Ultra-Broadband Dielectric Mirrors high reflect in the range 350 – 1100 nm and provide high average reflection in very wide range of angles of incidence (0°-50°). As maximum GDD reaches about 350 fs2, mirrors do not cause considerable pulse broadening for 1 ps and shorter pulses. These features make ultra-broadband mirrors a good choice to replace three or more convetional laser line mirrors, especially designed for Nd:YAG and its harmonics.
