The RPSQ-20-4M is a Right Angle Prism made from fused silica, specifically from the material ID fused sil mal-1965. This prism, with a geometry of 20 mm x 20 mm x 20 mm, is designed for use at a wavelength of 587.6 nm.
The Right Angle Prism is a type of prism where the incident and refracted rays make a right angle with each other. This prism is part of the Standard Type-RPB series offered by OptoSigma, a renowned vendor in the field of optics. The Right Angle Prism is a volume-based optical component, designed to alter the path of light in various optical systems.
The prism is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where the natural properties of the material are desired, or where additional coatings may interfere with the system's performance.
