48-275 25mm Dia. x 75mm FL Uncoated; UV Plano-Convex Lens
The 48-275 is a 25mm diameter, 75mm focal length uncoated plano-convex lens, designed for use in the ultraviolet (UV) spectrum. This lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is spherical in shape, with a base shape of circular. The plano-convex design features a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 34.39mm. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform thickness.
The lens has a thickness of 2.08mm at the edge and 4.43mm at the center. The effective focal length (EFL) is 75mm, and the back focal length (BFL) is 71.96mm. The lens is made from fused silica, specifically the material ID mal-1965. This material is known for its high transparency in the UV spectrum.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where a specific coating may interfere with the desired light path. However, it's important to note that uncoated lenses can be more susceptible to surface reflections and may require additional anti-reflective coatings.
The lens is currently in stock and available for purchase. For more information, including pricing and availability, please refer to the provided weblink.
