84-318 15mm Dia. x 30mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 84-318 is a UV Plano-Convex Lens, 15mm in diameter and 30mm in focal length, specifically designed for use within the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. This lens is sourced from the reputable optical vendor, Edmund Optics.
The lens is spherical in shape, with a base shape of a circle. The geometry of the lens includes a 15mm diameter, a 1.38mm edge thickness, and a 3.6mm center thickness. The effective focal length (EFL) is 30mm, and the front radius (R1) is 13.75mm. The back focal length (BFL) is 27.53mm, and both the inner and outer radii are 0mm.
The lens is constructed from fused silica material, identified as fused sil mal-1965 in the item data. This material is known for its excellent transparency and durability, making it suitable for a wide range of optical applications.
The lens features a VIS-NIR coating on both the front and back surfaces, identified as edm visnir0sp2002000. This coating is designed to enhance the lens' performance within the VIS-NIR spectrum, reducing surface reflections and improving transmission.
