| Metal Coated Mirror |
| |
After
aluminium (Al), silver (Ag) or Gold (Au) coating, the mirror
show high relfection perfance for very wide broadband. Generally,
we over coat the protective SiO2 or MgF2 layer outside the
metal layer to avoid the damage from the environment.
Metal coating is less sensitive to variations in incident
angle, polarization, and wavelength than dielectric coatings |
