OPB-25C05-1-5 25 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-25C05-1-5 is a 25 mm diameter N-BK7 round optical parallel flat window with a thickness of 5 mm, sourced from OptoSigma. This uncoated window is designed for use in optical systems where parallel light transmission is required.

The window is made from N-BK7, a popular optical glass known for its excellent optical properties, including low optical dispersion and a high Abbe number. This makes it an ideal choice for a wide range of applications, particularly where high-quality imaging is a priority.

The window's geometry is circular, with a diameter of 25 mm and a thickness of 5 mm. This thickness provides sufficient structural integrity while minimizing optical distortion. The window's flat shape ensures that light passing through it remains parallel, making it suitable for use in beam splitters, laser systems, and other applications where maintaining the direction of light is crucial.

The window is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where the natural properties of the glass are desired, or where additional coatings may interfere with the system's operation.

The window is designed to work at a wavelength of 588 nm, although it can be used across a broader spectrum depending on the specific requirements of the application. It is available for purchase directly from OptoSigma, and the provided weblink indicates that it is currently in stock.
