OPB-50C05-10-5 50 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-50C05-10-5 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 5 mm, providing a balance between durability and light transmission.

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 window is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, its natural properties make it a reliable choice for many applications.

The window is designed for use at a wavelength of 588 nm, which is in the yellow-orange part of the visible light spectrum. This makes it suitable for applications that use light in this range, such as certain types of lasers or light-based sensors.

The window is classified as a flat window, meaning it does not have any curvature. This is beneficial in applications where distortion-free light transmission is required. The window's thin lens shape further enhances its light transmission capabilities.
