OPB-25S05-4-5 25 x 25 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-25S05-4-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of applications. This window features a square shape with dimensions of 25 x 25 mm, making it suitable for use in systems where a compact, rectangular optical element is required.

The window is made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. N-BK7, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for a wide range of optical applications.

The window has a thickness of 5 mm, providing a good balance between durability and light transmission. Despite its thickness, the window is designed to maintain excellent parallelism, ensuring that light passing through it remains collimated.

This particular model is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While coatings can enhance the performance of an optical window in certain applications, an uncoated window can be a cost-effective solution when such enhancements are not necessary.

The window is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the vendor's website.
