Gold coated silicon or optical glass with dielectric coating. The scanning mirror is light weight rectangular total reflection mirror that used for high speed two-axis laser scanning system, which maintains reflectivity up to 99.7% or more at the angle of incidence ±25 degree, so it can withstand the laser power up to 200W or above. With its scientific design of shape and size , and its reliable quality, it is now widely applicable in two-axis laser scanning system, such as laser marking and stage lighting system. Customized size can be fabricated according to customer’s drawings and samples.
