OPB-30C05-20-2 30 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-30C05-20-2 is a 30 mm diameter N-BK7 round optical parallel flat window with a thickness of 5 mm, sourced from 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 type is widely used due to its low coefficient of thermal expansion, high transmittance in the visible and near-infrared regions, and its ability to be easily fabricated.

The window has a shape described as thin lens, indicating its minimal thickness relative to its diameter. This feature is beneficial in applications where the window needs to be as unobtrusive as possible, such as in beam delivery systems or optical fiber connectors.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in applications where the user desires to maintain the window's natural optical properties or where cost is a significant factor.

The window is in stock and available for immediate purchase, as indicated by its valid weblink status. Users can find more information about this product, including pricing and availability, on the OptoSigma website.
