SLB-50.8B-80P 50.8 mm Dia. x 81.8 mm FL; Double-Convex Lens Uncoated

The SLB-50.8B-80P is a double-convex lens with a diameter of 50.8 mm and a focal length of 81.8 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is uncoated. The lens is made of n-bk7 schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens features a base shape of a circle, with an edge thickness of 3 mm and a center thickness of 11 mm. The effective focal length (EFL) is 81.8 mm, while the back focal length (BFL) is 78.2 mm. The radii of curvature for the first and second surfaces are 83.04 mm and -83.04 mm, respectively. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.

The lens is designed to operate at a wavelength of 546.1 nm, making it suitable for applications that require high precision and accuracy in this wavelength range. The lens is spherical in shape, a common choice for applications that require minimal optical aberration.

Please note that the lens is uncoated, meaning it does not have any anti-reflective or protective coatings. This may affect the lens's performance in high-intensity light applications or environments where the lens may be subject to physical damage.
