48-276 25mm Dia. x 100mm FL Uncoated; UV Plano-Convex Lens
The 48-276 is a 25mm diameter, 100mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from the reputable optical vendor, Edmund Optics, this lens is a reliable choice for various optical systems.
The lens's geometry is characterized by a 2.05mm edge thickness and a 3.79mm center thickness, ensuring robustness and precision. Its base shape is circular, contributing to its wide range of applications. The lens's effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 45.85mm, indicating a moderate curvature that balances between light concentration and field of view.
The lens is made of fused silica (mal-1965), a material known for its excellent transparency in the ultraviolet spectrum. This makes the 48-276 particularly suitable for UV applications, where other materials might introduce unwanted absorption or scattering.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this might result in a slightly lower transmission compared to coated lenses, it also means that the lens is less prone to contamination and damage, making it a durable choice for harsh environments.
