The 84-279 is a 15mm diameter, 45mm focal length uncoated plano-convex lens, specifically designed for UV applications. Sourced from the renowned optical vendor, Edmund Optics, this lens is a part of their extensive catalog of optical elements.
This lens is a spherical lens with a base shape of a circle, featuring a plano-convex geometry. The lens's edge thickness is 1.59mm, while the center thickness is 3mm. The effective focal length (EFL) is 45mm, and the radius of curvature (R1) is 20.63mm. The back focal length (BFL) is 42.94mm, and both the inner and outer radii are 0mm.
The lens is made of fused silica (mal-1965), a material known for its excellent optical properties, including high transparency in the UV region. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this can be beneficial in certain applications where specific coatings might interfere with the desired spectral range.
The lens is designed to work with a wavelength of 587.6nm. It is currently in stock, as indicated by its weblink status, making it readily available for immediate use.
