48-277 25mm Dia. x 125mm FL Uncoated; UV Plano-Convex Lens

The 48-277 is a 25mm diameter, 125mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from the renowned optical vendor, Edmund Optics, this lens is a part of their extensive catalog of optical elements.

The lens is spherical in shape, with a base shape of a circle. It features an inner radius of 0 and an outer radius of 0, indicating a uniform curvature. The lens has a planar surface on one side and a convex surface on the other, with a radius of curvature of 57.3mm. The back focal length of the lens is 122.65mm, and the effective focal length is 125mm.

The lens is made of fused silica, identified as fused sil mal-1965 in the material database. This material is known for its excellent transparency in the UV region, making it ideal for UV applications. The lens has no coating, which means it is uncoated. This may result in a higher reflection loss compared to coated lenses, but it also means that the lens is less susceptible to damage from environmental factors.

The lens has a thickness of 2.04mm at the edge and 3.42mm at the center. This asymmetry in thickness is due to the curvature of the lens. The lens is in stock and available for immediate purchase, as indicated by the valid weblink status.
