DOP-25-4 N-BK7 Dove Prism; 25 mm Uncoated

The DOP-25-4 N-BK7 Dove Prism is a high-quality optical component designed for a wide range of applications. Manufactured by OptoSigma, this prism boasts a 25 mm x 25 mm square base and a length of 105.5 mm, making it a substantial yet manageable size for most systems.

The prism is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as BK7, is often the go-to choice for many optical applications due to its high homogeneity, low auto-fluorescence, and excellent transmission in the visible spectrum. The DOP-25-4 prism, in particular, is designed for a central wavelength of 632.8 nm, which is within the visible spectrum.

The Dove prism shape is unique in that it inverts and reverses the image, making it ideal for applications such as beam steering, image rotation, and optical image stabilization. Despite its complex shape, the prism's surfaces are designed to be flat within 1/4 wave, ensuring high-quality optical performance.

Notably, this prism is uncoated. While coatings can enhance the performance of optical components in certain applications, an uncoated prism can be advantageous in situations where broadband anti-reflection coatings are not required or desirable.
