OFB-25S05-10 25 x 25 mm N-BK7 Square Precision Ground Flat Window; t=5 mm Uncoated

The OFB-25S05-10 is a high-quality optical window from OptoSigma, a leading vendor in the field of optical components. This specific model is a 25 x 25 mm square precision ground flat window, designed with a thickness of 5 mm, making it an ideal choice for various optical applications.

The window is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as Schott glass, is widely used in the optical industry due to its low coefficient of thermal expansion, high transmittance in the visible and near-infrared regions, and excellent homogeneity.

The OFB-25S05-10 is a flat window, meaning it has no curvature, making it suitable for applications where a flat surface is required. The window is uncoated, which means it does not have any additional layers to enhance its optical properties. However, its high-quality surface accuracy and surface quality make it a reliable choice for various applications.

This window is designed for a wavelength of 588 nm, which is in the yellow-orange part of the visible light spectrum. It is suitable for use in systems operating at this wavelength, or in systems where broadband transmission is required.
