DPB-20-10H N-BK7 Equilateral Prism; 20mm Uncoated

OptoSigma's DPB-20-10H is an equilateral prism made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This prism has a square base with each side measuring 20mm, making it suitable for a wide range of applications. The prism's equilateral shape, where all three angles are equal, is particularly useful for dispersion and total internal reflection applications.

The prism's material, N-BK7, is a type of borosilicate glass known for its low coefficient of thermal expansion and high transmittance in the visible and near-infrared regions. This makes the DPB-20-10H prism suitable for use in environments with varying temperatures.

Notably, this prism is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost is a concern. However, it's important to note that uncoated prisms may have higher reflectivity at the air-glass interface, which could affect the overall system performance.
