48-273 25mm Dia. x 38mm FL Uncoated; UV Plano-Convex Lens
The 48-273 is a 25mm diameter, 38mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from the renowned optical vendor, Edmund Optics, this lens is a reliable choice for various optical systems.
The lens features a base shape of a circle, with a thickness of 1.96mm at the edge and 7.25mm at the center. The effective focal length (EFL) is 38mm, and the radius of curvature (R1) is 17.42mm. The back focal length (BFL) is 33.03mm, and the lens has no inner or outer radius, indicating a flat surface on the opposite side of the convex curve.
The lens is made of fused silica (mal-1965), a material known for its excellent transmission properties in the ultraviolet region. The wavelength for this lens is 587.6nm, which falls within the visible light spectrum. However, the lens's design and material make it particularly suitable for UV applications.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflectivity, it also means the lens is more cost-effective and suitable for applications where such coatings are not necessary or desirable.
