OPB-20S05-4-5 20 x 20 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-20S05-4-5 is a 20 x 20 mm N-BK7 Square Optical Parallel Flat Window, featuring a thickness of 5 mm and sourced from the reputable vendor, 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.

The window's base shape is rectangular, with dimensions of 20 x 20 mm, providing a substantial surface area for light transmission. The thickness of 5 mm, denoted as 't=5 mm', contributes to the window's robustness and ability to withstand external pressures.

The material of this window is N-BK7, a type of borosilicate glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. This specific N-BK7 is sourced from Schott, a leading manufacturer of optical glass.

The window is designed for use at a wavelength of 588 nm, making it suitable for applications that operate within this range, such as certain types of lasers or optical sensing systems.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where maintaining the window's natural optical properties is crucial.
