DICHROICS 

A dichroic filter has spectral characteristics similar to a dichroic mirror, but is used for normal incidence, whereas a dichroic mirror is used for non-normal incidence. Standard dichroic filters are available as Yellow, Magenta, Cyan, Blue, Green and Red filter types.

Maximum Dimensions: up to 200mm (Æ or diagonal)

Optical Specifications
 

Filter Type   50% T (nm)
Yellow                520±15
Magenta           495±15, 605±15
Cyan                   590±15
Blue                    495±15
Green                 505±15, 575±15
Red                     610±15

Typical spectral characteristics

A multilayer coating of dielectrics enables a dichroic mirror to reflect a specific wavelength region and transmit other regions. The three standard dichroic mirrors listed below can be combined to separate or combine the three primary colors of white light. Types available are Blue-, Green-, or Red-reflecting mirrors.
