Dichroic Mirror/Filter/Beamsplitter

Dichroic mirror, dichroic filter and dichroic beamsplitter are a special designed thin-film coating which selectively reflect/pass a small wavelength range of light. They are characteried by the light they reflect, pass or both.

Applications of Dichroic Mirror/Filter/Beamsplitter

In fluorescence microscopy, dichroic filters are used as beam splitters to direct illumination of an excitation frequency toward the sample and then as an analyzer to reject that same excitation frequency but pass a particular emission frequency.

Some LCD projectors use dichroic filters instead of prisms to split the white light from the lamp into the three colours before passing it through the three LCD units.

Dichroic mirrors are used as Laser Harmonic Separators. They separate the various harmonic components of frequency doubled laser systems by selective spectral reflection and transmission.
