Polarizing Beamsplitter Cubes
The OFR Broadband Polarizing Beamsplitter prism cube, mounted on an ACB 3-Axis Aiming Base comprises the Polarizing Beamsplitter Module. This splits the collimated laser beam into its S and P polarized components, with the S (vertical) component reflecting 90°, and the P (horizontal) component continuing undeviated. Separation of polarization of the two components is > 1000:1 (30dB).

50/50 Plate Beamsplitters
An OFR Laser Beamsplitter Plate, mounted on an ACB 3-Axis Aiming Base, comprises the Beamsplitter Module. These produce a 50/50 split with unpolarized light within the wavelength band specified. The beamsplitter coating is dielectric, and all air surfaces are AR coated. When ordering, specify wavelength of operation. Beamsplitter Modules are intended for applications requiring access to two or more output beams. Split ratios other than 50/50 are available on special order. For additional information on other beamsplitters see PRECISION OPTICAL COMPONENTS.

Wavelength	Order as
450- 675 nm	VIS
630 - 860 nm	VNIR

Broadband PSP Beamsplitters

In most fiber-optic applications it is necessary to maintain the of light in the system. However, if an ordinary beamsplitter is used, the SOP will be changed. An “ordinary” beamsplitter is described as a plate of glass at 45° that reflects (S) and transmits (P) incident light, whether coated or uncoated. This is because this type of beamsplitter affects the SOP of the S and P beams. See rear cover of PRECISION OPTICAL COMPONENTS brochure in this catalog for equations.

The OFR PSP Beamsplitter maintains a constant amplitude split ratio for any input SOP. The PSP Beamsplitter produces a 50/50 split within 3% for both output beams. Other split ratios are available on a custom basis. A special PSP Beamsplitter with 4% reflection and 96% transmission is used to sample the optical beam for the purpose of mounting power.

Please contact OFR with your application information.
