OPB-50C08-20-2 50 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=8 mm Uncoated

The OPB-50C08-20-2 is a high-quality optical window, specifically designed for precision applications. This window is manufactured by OptoSigma, a renowned vendor known for their extensive range of optical components. The window features a base shape of a circle with a diameter of 50 mm, making it suitable for a wide range of applications.

The window is made from N-BK7, a type of borosilicate glass that is known for its excellent optical properties. This material is often used in high-precision applications due to its low coefficient of thermal expansion and its high resistance to thermal shock. The window has a thickness of 8 mm, providing a good balance between durability and light transmission.

The window is designed for use at a wavelength of 588 nm, making it suitable for a wide range of applications in the visible light spectrum. It is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where a natural, unaltered optical surface is required.

The window is classified as a flat window, meaning it does not have any curvature. This makes it ideal for applications where a flat, undistorted optical surface is required. The window is also thin, which can be beneficial in applications where weight or thickness is a concern.
