Beamsplitters are optical components used to split incident light at a designated ratio into two
separate beams. Additionally, beamsplitters can be used in reverse to combine two di erent beams
into a single one. Beamsplitters are often classi ed according to their construction: cube or plate.
STANDARD BEAMSPLITTERS are commonly used with unpolarized light sources, such as natural
or polychromatic, in applications where polarization state is not important. They are designed to
split unpolarized light at a speci c Re ection/Transmission (R/T) ratio with unspeci ed polarization
PLATE BEAMSPLITTERS
Plate beamsplitters are available in a wide range of sizes, coatings, and substrates and o er a lightweight solution for a wide range of applications.
Designed for 45° angle of incidence, these beamsplitters are available for applications from UV through Infrared.

POLARIZING BEAMSPLITTERS are designed to split light into re ected S-polarized and
transmitted P-polarized beams. They can be used to split unpolarized light at a 50/50 ratio, or for
polarization separation applications such as optical isolation.
NON-POLARIZING BEAMSPLITTERS split light into a speci c R/T ratio while maintaining the
incident light’s original polarization state. For example, in the case of a 50/50 non-polarizing beamsplitter,
the transmitted P and S polarization states and the re ected P and S polarization states are
split at the design ratio. These beamsplitters are ideal for maintaining polarization in applications
utilizing polarized light.
DICHROIC BEAMSPLITTERS split light by wavelength. Options range from laser beam combiners
designed for speci c laser wavelengths to broadband hot and cold mirrors for splitting visible
and infrared light. This type of beamsplitter is commonly used in uorescence applications.
