89-413 5mm Dia. x 20mm FL Uncoated; UV Plano-Convex Lens
The 89-413 is a 5mm diameter, 20mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from the reputable 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. The geometry of the lens includes a 1.15mm thickness at the edge, increasing slightly to 1.5mm at the center. The effective focal length (EFL) is 20mm, and the radius of curvature (R1) is 9.17mm. The back focal length (BFL) is 18.97mm, and both the inner and outer radii are 0mm, indicating a plano surface on one side of the lens.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent transmission properties in the UV range, making it ideal for UV applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its specifications and properties, this lens is a suitable choice for users looking for a high-quality, UV-compatible plano-convex lens.
