Benefits of the Scanning Mirror

CRYLINK provides various types of high-power X/Y scanning mirrors, mainly including silicon scanning mirrors and quartz scanning mirrors, for laser scanning mirror systems above 6Kw. Laser wavelengths include 355nm, 532nm, 1064nm, and 10.6μm.

Description

Thanks to the special coating technology, it is possible to ensure that the mirror dissipates heat quickly and with little temperature rise at the laser focus during use. The amount of change in the shape of the used surface is very small. The mirror has a high threshold of laser damage, which can meet the requirements of long-term stable use of the scanning mirror.

High-Quality Substrate

· High-quality substrate material, rough machining, and polishing quality are the main factors affecting the performance of optical elements.

· The mirrors are made of imported Corning 7979 and 7980 materials with guaranteed quality;

· For high-power laser optical elements, it is particularly required that the edge collapse of the substrate should be well controlled, otherwise the mirror's film will crack and extend in the process of use.

· The surface finish and roughness of the substrate will greatly affect the damage threshold of the film.

· The surface shape of the substrate will affect the shape of the laser spot, so PV and RMS need to be controlled.

High Coating Quality

· Good reflectivity of the lens under different incident angles.

· Under different incident angles, the reflectivity of the probe light is high enough.

· After coating, the deformation of the substrate should be small enough. The stress relief design of the film must be considered.

· Good laser damage threshold.

Verdict

CRYLINK’s laser scanning mirror products have high-quality polished substrates, low residual stress in the film layer of the lens after coating, and good surface shape.
