Laser Mirror

Laser Mirrors are used in a wide range of products based upon laser optics. There are some specifications of laser mirrors below.

Features of Laser Mirror:

• Made from BK7 glass, fused silica or UV grade fused silica.
• Polished to high surface quality.
• Standard substrates are available with a variety of radii of concave curvature.
• Wide selection of shapes and sizes, with plano, spherical or cylindrical surfaces are also available.

Many manufactures offer three substrate materials, spanning a range of thermal expansion coefficients. For applications in which thermal shock is absent and thermal stability is not critical, BK7 glass is a suitable and inexpensive material. For applications requiring high thermal stability or involving severe thermal shock, fused silica and UV grade fused silica is a good choice.

Part Number Description:

LM-1064-D-T-R-A-%-yy

• LM: laser mirror. R>99.5%.
• 1064: laser wavelength, nm.
• D: mirror diameter, m. If rectangular, it is AxB.
• T: thickness, mm.
• R: radius of curvature, mm. It is flat mirror if ther is no this number. It is plano-convex if it is minus.
• A: incidence angle, degree. It is normal incidence if there is no this number.
• %: tranmittance of output coupler.
• yy: other marks.

Remark:

• Regarding f50x3mm, 50 means diameter, 3 means thickness, unit is mm.
• Regarding R=10%, R means reflectivity and unit is %.
• Regarding T=10%, T means transmittance and unit is %.
• Regarding R=50mm, R means radius of curvature and unit is mm.
• HR1064nm means high reflectivity at 1064nm (>98%).
• HT532nm means high transmittance at 532nm (>98%).
• Plano-concave means that one surface is flat and another surface is concave.
