OPB-25C03-1-5 25 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-25C03-1-5 is a 25 mm diameter N-BK7 round optical parallel flat window with a thickness of 3 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 high-quality borosilicate glass known for its excellent optical properties. This material is often used in precision optical applications due to its low coefficient of thermal expansion, high homogeneity, and excellent transmission in the visible spectrum. The window has a diameter of 25 mm, providing a generous aperture for light transmission.

The thickness of the window, at 3 mm, is sufficient to provide structural rigidity while minimizing optical distortion. The uncoated surface allows for broadband transmission but may require additional coatings for specific applications.

This window is suitable for use in a variety of optical systems, including beam expanders, laser systems, and interferometers. It is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
