What does a slot-mounted beam splitter look like
These beamsplitters have a polka-dot-like surface. Half of the beamsplitter's surface comprises dots, which can reflect materials using photolithography or mechanical masking (with any desired ratio). This offers an almost continuous R/T ratio regardless of the viewing angle. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Beamsplitters are often classified according to their construction: cube or plate. Thorlabs offers a wide range of optical beamsplitters. Our plate beamsplitters have a coated front surface that determines the beam splitting ratio while the back surface is wedged and AR coated in order to minimize ghosting and interference effects. Different types of beam splitters exist, as described in the. An Optical Beamsplitter is an optic or optical device that is used to split a beam of light in two.
