84-312 30mm Dia. x 50mm FL VIS 0deg Coated; UV Plano-Convex Lens VIS 0° 425-675nm
The 84-312 is a 30mm diameter x 50mm focal length Plano-Convex lens, designed for visible light with a wavelength of 587.6nm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from fused silica (mal-1965), a material renowned for its excellent optical properties, including high transparency and resistance to thermal shock. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, which is designed to enhance the lens's performance in the visible light spectrum (425-675nm).
The lens's geometry is characterized by a 1.41mm edge thickness and a 7mm center thickness. The inner radius is 0mm, while the outer radius is also 0mm, indicating a planar surface on the uncoated side of the lens. The lens's effective focal length (EFL) is 50mm, and the radius of curvature (R1) is 22.92mm. The back focal length (BFL) is 45.2mm.
This lens is a Spherical Lens, which means it has a spherical surface. The base shape is circular, making it suitable for a wide range of optical applications. The lens's coating and geometry make it an ideal choice for applications that require high-quality imaging in the visible light spectrum.
