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.
