46-312 9.0mm Dia. x -18 FL; UV-AR Coated; UV Plano-Concave Lens 250-425nm
This 9.0mm diameter plano-concave lens, model 46-312, is sourced from Edmund Optics and features a focal length of -18. It is designed for use with ultraviolet light, specifically within the wavelength range of 250-425nm. The lens is made from fused silica, ensuring high transmittance and durability.
The lens's geometry includes a thickness of 3.15mm at the edge and 2mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The front and back surfaces of the lens are coated with the EDM UV Standard Curve, providing excellent UV-AR coating. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
The lens's base shape is circular, and it is classified as a spherical lens due to its curvature. The lens is in stock and available for immediate purchase, as indicated by its weblink status. For more detailed information, please refer to the vendor's website using the provided weblink.
