The 45-701 is a 9.0mm diameter Plano-Concave lens with a focal length of -18mm, sourced from Edmund Optics. This lens is uncoated and designed for use with UV light, making it suitable for applications in the ultraviolet spectrum.
The lens features a concave shape with a center thickness of 2mm and an edge thickness of 3.15mm. The base shape is circular, and the lens is made from fused silica, identified as fused sil mal-1965 in the material database. This material is known for its excellent transmission properties in the UV range, making it an ideal choice for UV applications.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple, straightforward design. The wavelength for this lens is 587.6nm, which is in the visible light spectrum. However, the lens's uncoated state and UV-specific design suggest that it is intended for use in UV applications rather than visible light.
