OPB-10S05-4-5 10 x 10 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-10S05-4-5 is a 10 x 10 mm N-BK7 Square Optical Parallel Flat Window, boasting a thickness of 5 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 reflections and losses.

The window's base shape is rectangular, with dimensions of 10 mm in both the a and b directions. The thickness, or t, of the window is 5 mm, providing sufficient structural integrity while maintaining a low profile. The material used for this window is N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity.

The window is designed to operate at a wavelength of 588 nm, making it suitable for a wide range of optical applications. The shape of the window is that of a thin lens, indicating that it has been precisely ground and polished to ensure excellent optical quality.

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.

The window's current status is in stock, and more information about it can be found on the OptoSigma website.
