RPSQ-25.4-4M Fused Silica Right Angle Prism; 25.4 mm Uncoated

The RPSQ-25.4-4M is a right-angle prism made from fused silica, a high-quality material known for its excellent optical properties. This prism, sourced from OptoSigma, is uncoated and has a square geometry with dimensions of 25.4 mm for both the 'a' and 'b' parameters, and a length of 25.4 mm.

The right-angle prism is a type of optical prism used to change the direction of light, and in this case, it's designed to provide a 90-degree deviation. The 'RPSQ' in the name stands for 'Right Angle Prism, Square', indicating its shape and function.

The prism is made from fused silica, also known as fused quartz, which is a form of silica containing minimal amounts of impurities. This material is prized for its low coefficient of thermal expansion, making it resistant to thermal shock. It also has a high transmittance across a wide spectrum, from the ultraviolet to the infrared region, making it suitable for various optical applications.

The prism is uncoated, meaning it doesn't have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired. However, it's important to note that uncoated prisms can be more susceptible to surface damage and may require more careful handling.

The prism's web links are valid and indicate that it's currently in stock, making it readily available for immediate use.
