Flat mirrors are reflective coated and then over-coated for protection. Excellent for imaging systems, laser applications, as well as for holography, optical path folding and as reflectors for auto-collimating requirements.
The coating type include enhanced Aluminum coating, protected Silver coating, protected Gold coating and dielectric high reflection coating. According to the coating surface, it can also be divided into front surface mirror and back surface mirror, or first surface mirror and second surface mirror.
