36-688 18mm Dia x 54mm FL Uncoated; UV Plano-Convex Lens

The 36-688 is a Plano-Convex lens with a diameter of 18mm and a focal length of 54mm, sourced from the reputable optical vendor, Edmund Optics. This lens is designed for use in the ultraviolet (UV) spectrum, specifically at a wavelength of 587.6nm.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where minimal reflection or dispersion is required. However, it may also mean that the lens is more susceptible to environmental factors such as dust, dirt, or moisture, which can affect its performance.

The geometry of the lens includes an edge thickness of 1.81mm and a center thickness of 3.5mm. The base shape is circular, and the lens features a spherical design. The inner and outer radii are both zero, and the lens has a back focal length of 51.6mm.

This lens is made from fused silica, a material with a high transmittance across a wide range of wavelengths, making it ideal for UV applications. The material ID for this lens is fused sil mal-1965.
