Dichroic Mirror/Filter/Beamsplitter, Separating Or Combining
Wavelengths Overview: A Dichroic Mirror/Filter/Beamsplitter, also down as a dual-band
mirror, dual-wavelength mirror, or dichroic reflector, is a
specialized mirror which has different optical properties at two
different wavelengths. For instance, a dichroic mirror might be
reflective below a cut-on wavelength, then transmissive at longer
wavelengths. Dichroic mirrors are manufactured using electron beam deposition,
ion beam sputtering (IBS) and ion-assisted deposition (IAD).
State-of-the-art thin film deposition techniques allow us to ensure
each dichroic mirror produced at our factory meets the exact
specifications necessary to the application for which it is
produced. The hard dielectric coatings used in our dichroic mirrors make them
uniquely durable, they are built to withstand even high power
lasers and are thermally stable under normal conditions. These dichroic mirrors can be used to split or combine two beams of
different wavelengths, and they have important applications in the
filtering of spectral components and in fluorescence microscopy.
