Front surface mirror is an optical component which has high reflectivity and uniformity in the whole band of visible light.On the surface of optical glass, a metallic silver(or aluminum) film is coated with a vacuum coating to reflect the incident light.Front surfce mirror with high reflection can improve laser's output power exponentially.Because it is first surface reflection , the reflection image will not be fuzzy and will not have double image.If you use coated high reflective front surface mirror, the image will not only be high brightness but also be more clear.The color will also be more vivid.
