OPB-50C02-1-5 50 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=2 mm Uncoated

The OPB-50C02-1-5 is a high-quality optical window manufactured by OptoSigma, a leading global provider of optical components. This window is designed for use in a wide range of optical systems and applications, offering excellent performance and reliability.

The window features a base shape of a circle with a diameter of 50 mm, providing a large aperture for maximum light transmission. It has a thickness of 2 mm, strikeing a balance between durability and light weight. The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This makes it an ideal choice for applications that require high precision and stability.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where such coatings are not required or desirable, such as when the window is used in a high-vacuum environment. However, it should be noted that uncoated windows can have higher reflectivity than coated ones, which may affect the performance of certain optical systems.

The window is designed for use at a wavelength of 588 nm, making it suitable for a wide range of visible light applications. Its geometry is that of a thin lens, which helps to minimize optical aberrations and distortions.
