In its most common form, a cube, a beam splitter is made from two triangular glass which are glued together at their base using polyester,, or urethane-based adhesives. If not repeat When finished, only outside lines of both scales should directly overlap (they are same distance apart 200 μm)In the Brewster's Angle experiment, the Beam Splitter is used with a High Sensitivity Light Sensor to compensate for any variation in the intensity of the laser beam. A beam splitter or beamsplitter is an optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. Aligning the laser beam along the rails For the alignment along the rails, which carry the optical components of the first and second telescope system, one can use Ø1/2" mirrors (BB05-E02, Thorlabs) mounted on kinematic mounts (KM05/M, Thorlabs) and larger Ø1" corner mirrors (BB1-E02, Thorlabs).
