Standard Precision Beam Splitter Cubes

MSE Supplies offers both polarizing and non-polarizing Beam Splitter Cubes with edge length between 10mm and 30mm. The wavelength for standard beam splitter cubes is Visible Light (400-700 nm) and the standard splitting ratio T:R (transmission vs reflection) is 50:50 while other wavelength (between 250-2000 nm) and splitting ratios (between 3:7 to 9:1) can also be customized.

Beam Splitter (also known as Beamsplitter) is an optical element that splits a beam of light in two. It can also reverse the process by combining two beam of light into one. By shape, it can be classified into cube beam splitters and plate splitters, in which the key optical element is splitter cube and splitter plate, respectively. A beam splitter cube is constructed by gluing two right angle prisms together to form a cubic shape. Dielectric coating is applied to the hypotenuse of one of the prisms to separate the incident beam. There are two models of beam splitter cubes: polarizing and non-polarizing. The polarizing beam splitter cube allows the p-component (light has electric field that is oscillating parallel to the incident plain) to pass while reflect the s-component (light has electric field that is oscillating perpendicular to the incident plain). While the non-polarizing beam splitter cube only splits the light by intensity but is oscillation direction independent. Different coating can split light of different wavelength, including visible light (400-700nm), near infrared light (700-1100nm) and infrared light (>1100nm). Beam splitter is widely used in many optical systems, such as interferometers, optic telecommunication, etc.
