OPB-25C02-4-5 25 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=2 mm Uncoated

The OPB-25C02-4-5 is a 25 mm diameter N-BK7 round optical parallel flat window with a thickness of 2 mm, sourced from the reputable vendor OptoSigma. This window is a type of flat window, designed with a base shape of a circle, making it suitable for a wide range of optical applications.

The window is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. This Schott glass variant is often used in high-performance applications due to its low coefficient of thermal expansion and high Abbe number.

The window is designed to operate at a wavelength of 588 nm, making it suitable for applications that require high transmittance at this specific wavelength. The window's shape is defined as a thin lens, indicating its minimal thickness relative to its diameter, which contributes to its lightweight nature and ease of integration into optical systems.

Notably, this window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This may be beneficial in applications where the natural properties of N-BK7 are desired, or where cost-effectiveness is a priority.
