Beamsplitter Prisms

Zoolied provides 7*7*7mm 1:1 Optical Glass Prism PBS Cube.

Zoolied cube beamsplitter unlike a plate beamspitter (often a plano-window with dielectric and anti-reflection (AR) coatings), a cube beamsplitter is comprised of two Right Angle Prisms. Typically, the two prisms are adhered together, but optical contacted beamsplitters exist as well. In order to "split" the incident beam, a dielectric coating is applied to the hypotenuse of one of the right angle prisms. This coating reflects a portion of the beam in one direction, and allows the other to be transmitted through the entire cube. The type of coating determines whether this split is 50/50, 30/70, or 70/30, as well as the specific wavelengths and/or polarizations that are transmitted or reflected. As a result of the precise alignment required by a skilled optician to adhere or contact the two hypotenuses together, it is better to purchase a complete beamsplitter assembly rather than try to use two identical right angle prisms.

Optical Prisms are used to redirect light at a designated angle. Optical Glass Prisms are ideal for ray deviation, or for adjusting the orientation of an image. An Optical Prism’s design determines how light interacts with it. When light enters an optical glass prism it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate. For example, when light enters Optical glass prism, it reflects off a single surface, causing the light to redirect at 90°. When light enters a wedge prism, though, a change in substrate thickness causes the light to deviate through refraction.

Zoolied offers a wide range of High Precision Prisms in a variety of designs, substrates, or coating options. Designs include Right Angle, Amici, Penta, Schmidt, Wedge, Anamorphic, Equilateral, Dove, or Rhomboid prisms, in addition to Corner Cube Retroreflectors or Light Pipe Homogenizing Rods. Anti-reflection coatings include MgF2, UV-VIS, UV-AR, VIS 0°, VIS-NIR, or multiple laser line options.
