SLB-50.8-700P 50.8 mm Dia. x 700.0 mm FL; Plano-Convex Lens Uncoated

OptoSigma offers the SLB-50.8-700P, a Plano-Convex lens with a 50.8 mm diameter and a focal length of 700.0 mm. This lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces.

The lens's geometry is characterized by a thickness of 3 mm at the edge and 3.9 mm at the center. The radius of curvature (R1) is 363.3 mm, and the back focal length (BFL) is 697.4 mm. The lens's inner and outer radii are both 0 mm, indicating a planar surface on one side and a curved surface on the other.

This lens is designed for use at a wavelength of 546.1 nm, which is in the middle of the visible light spectrum. It is suitable for a wide range of applications, including imaging, illumination, and beam shaping. However, due to its uncoated nature, it may exhibit higher reflectivity and lower transmission compared to coated lenses.
