OFB-25S05-4 25 x 25 mm N-BK7 Square Precision Ground Flat Window; t=5 mm Uncoated

The OFB-25S05-4 is a high-quality optical window from OptoSigma, designed with precision and durability in mind. This window is a 25 x 25 mm square, featuring a thickness of 5 mm, making it an ideal choice for various optical applications.

The window is made from N-BK7, a popular glass type known for 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 a versatile choice for many optical systems. This specific window is sourced from Schott, a renowned glass manufacturer, ensuring top-tier quality and reliability.

The OFB-25S05-4 is designed in a flat window configuration, which is ideal for applications that require minimal optical distortion. This design is often used in beam splitters, filters, and other optical components where maintaining a flat surface is crucial.

Notably, this window is uncoated. While coatings can enhance certain optical properties, an uncoated window offers simplicity and versatility. It can be used in a wide range of wavelengths, including the visible spectrum, without the potential complications that coatings can introduce.
