37-783 12.0mm Dia. x 25mm FL; Uncoated; Plano-Convex Lens
The 37-783 is a Plano-Convex Lens with a diameter of 12.0mm and a focal length of 25mm, sourced from the reputable optical vendor, Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface.
The lens's geometry is characterized by its diameter, thickness at the edge, and thickness at the center. The diameter is a consistent 12.0mm, while the thickness at the edge is 1.22mm and the thickness at the center is 2.7mm. The effective focal length (EFL) is 25mm, indicating the distance at which the lens will focus parallel rays of light.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The wavelength of 587.6nm suggests that this lens is designed for use in the visible light spectrum.
The lens's shape is spherical, with a radius of curvature of 12.92mm for the convex surface. The back focal length (BFL) is 32.22mm, which is the distance from the rear surface of the lens to the focal point. The lens has no inner or outer radius, indicating a uniform curvature.
