Visible Round Dichroic Filters / DIM
Mirrors of 3 fundamentals colors RGB for use in color separation. No absorption effects because of the dielectric optical coating, the transmitting and reflecting are applicable. For light transmitting, choose 2 colors out of the RGB dichroic mirror for color separation. (For example:DIM RED + DIM GRE = Reflect red, reflect green, and transmit blue)
The switching from reflecting and transmitting is steep; it is usable as a wavelength separation filter.Easy to be used as a variable wavelength filter by changing the angle of incident.
Use the 3 fundamentals colors RGB together, a white color can be obtained.
