| Mirror |
| Front
surface mirrors are coated with aluminum or dielectrics
for maximum reflection. Simphoton provides both kinds of
front surface mirrors: Metal coated mirror and Dielectric
coated mirror. |

|
Substrate:
1. Commercial quality flat window or precision window.
Please refer to the optical
window page. Unpolished back surface is also available.
2. Plano concave substrate. After HR coated on the concave
face, it's a concave mirror.

|
| Metal
Coated Mirror |
| Standard
items are supplied front surface-coated with metal (Aluminium,
Silver or Gold) overcoated with silicon monoxide (SiO2)
or magnesium fluoride (MgF2). |
|
|
| Dielectric
Coated High Reflection Mirror (Laser mirror) |
| After dielectric
HR coaitng, the mirror have the very high relection for
specified single wavelength or broadband wavelength. For
laser application, the mirror surface has been coated with
very high reflection (general >99.8%) at the laser wavelength.
|
|
|
| Dichroic
Mirror / Beamsplitter |
With special designed
multi layer dielectric coating, the mirror reflect some
wavelength and transmission other wavelength at the same
time.
It can be used to splitter or conbine different wavelength.
It can be also used in SHG laser system as Harmanic Separators. |
|
|
| Concave
Mirror |
| After metal or
dielectric high reflection coated on the concave substrates,
it's a concave mirror. Concave mirror can be focus the light
beam or imaging as a lens. The focal length of concave mirror
is half of the curvature radius. |
