SLB-50.8B-300P 50.8 mm Dia. x 300.8 mm FL; Double-Convex Lens Uncoated
The SLB-50.8B-300P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 50.8 mm and a focal length of 300.8 mm, is designed for use in a wide range of optical applications.
The lens is made from n-bk7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The base shape of the lens is circular, and it features a spherical geometry with a center thickness of 5 mm and an edge thickness of 2.9 mm. The lens has a back focal length of 299.1 mm and a clear aperture, making it suitable for use with a variety of optical systems.
The SLB-50.8B-300P is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance at the air-glass interfaces, it also means the lens is more versatile and can be used in a wider range of wavelengths. The lens is designed to operate at a wavelength of 546.1 nm, but its performance is not significantly affected by small variations in this value.
