84-308 15mm Dia. x 30mm FL VIS 0deg Coated; UV Plano-Convex Lens VIS 0° 425-675nm
The 84-308 is a 15mm diameter, 30mm focal length Plano-Convex lens, sourced from Edmund Optics. This lens is designed for visible light applications, with a wavelength of 587.6nm, and is coated with a standard curve Vis-0 coating on both the front and back surfaces.
The lens is made from fused silica, a material with a high damage threshold and excellent transmission properties in the ultraviolet, visible, and near-infrared regions of the spectrum. The plano-convex geometry of the lens, where one surface is flat and the other is curved, provides a large, flat focal plane, making it ideal for use in imaging systems.
The lens has a 1.38mm edge thickness and a 3.6mm center thickness, with a 13.75mm radius of curvature on the curved surface. The back focal length is 27.53mm, and the effective focal length is 30mm. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
This lens is designed to work with light in the 425-675nm range, making it suitable for a wide range of visible light applications. The Vis-0 coating on the lens further enhances its performance in the visible spectrum, reducing surface reflections and increasing transmission.
