OPB-50C08-10-5 50 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=8 mm Uncoated

The OPB-50C08-10-5 is a high-quality optical window from OptoSigma, a leading vendor in the optical industry. This window is designed with a base shape of a circle, making it suitable for a wide range of applications that require uniform light transmission. The window has a diameter of 50 mm and a thickness of 8 mm, providing a robust and stable platform for optical systems.

The material used for this window is N-BK7, a type of borosilicate glass known for its excellent optical properties. N-BK7, also known as BK7, is a common material in optical systems due to its low dispersion and high transmission in the visible spectrum. The specific N-BK7 used in this window is sourced from Schott, a renowned manufacturer of high-precision glass materials.

The window is designed for use at a wavelength of 588 nm, making it suitable for applications that operate in the yellow-orange part of the visible spectrum. The window is uncoated, meaning it does not have any additional layers applied to modify its optical properties. This makes it ideal for applications where the natural properties of N-BK7 are desired.

The window is classified as a flat window, indicating that its surfaces are parallel to each other. This is crucial in optical systems where maintaining a straight light path is essential. The window's thin lens shape further enhances its optical performance, ensuring minimal distortion and high light transmission.
