49-963 20mm Dia. x 60mm FL Uncoated; UV Plano-Convex Lens
The 49-963 is a 20mm diameter, 60mm focal length Plano-Convex lens, uncoated and optimized for UV light at a wavelength of 587.6nm. This lens is sourced from Edmund Optics, a leading vendor in the optical industry.
The lens features a base shape of a circle, with a thickness of 1.62mm at the edge and 3.5mm at the center. The effective focal length (EFL) is 60mm, and the radius of curvature (R1) is 27.51mm. The back focal length (BFL) measures 57.6mm, and the lens has no inner or outer radius, indicating a uniform curvature.
The lens material is fused silica, identified as mal-1965 in the Edmund Optics material database. This material is known for its high transparency in the UV range, making it suitable for applications such as UV spectroscopy, fluorescence microscopy, and other UV-based imaging techniques.
The lens is uncoated, which means it does not have any anti-reflective or protective coatings. While this may result in a higher reflectivity at the air-glass interfaces, it does not introduce any potential coating-induced aberrations or spectral shifts.
