A beamsplitter is an optical device for dividing a beam into two or more separate beams. A simple beamsplitter may be a very thin sheet of glass inserted in the beam at an angle to divert a portion of the beam in a different direction. A more sophisticated type consists of two right-angle prisms cemented together at their hypotenuse faces. The cemented face of one prism is coated, before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. In a color television camera, for example, a three-way beamsplitting prism is employed in which multilayer films are deposited on the interfaces to divert red and green light to two vidicons, leaving the blue image to pass through to the third vidicon tube.
Accurate deposition of 65-145µm reflective pads repeating every 150µm, produces broadband optical beamsplitters with near constant reflection: transmission ratios of 20:80 to 90:10 across the 250nm to 2.0um spectral range with negligible angle sensitivity. Request a quote today!
