OPB-10S03-10-5 10 x 10 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-10S03-10-5 is a 10 x 10 mm N-BK7 Square Optical Parallel Flat Window, featuring a thickness of 3 mm and manufactured by OptoSigma. This window is a type of flat optical component designed to maintain the direction of an incident light beam while minimizing its loss of power due to reflection or absorption.

The window is made of N-BK7, a type of borosilicate glass known for its excellent optical properties, including a high refractive index and low dispersion. This makes it an ideal material for various optical applications, particularly in the visible spectrum, as demonstrated by its wavelength of 588 nm.

The window's rectangular base shape, with dimensions of 10 x 10 mm, is designed to provide a larger area for light transmission compared to circular windows of the same diameter. This can be beneficial in applications where a larger aperture is required.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in higher reflective losses compared to coated windows, it also means that the window can be used in a wider range of wavelengths without the risk of coating damage.
