48-287 25mm Dia. x 125mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 48-287 is a UV-AR coated plano-convex lens, boasting a 25mm diameter and a focal length of 125mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components. The lens features a standard UV curve coating on both the front and back surfaces, designed to filter ultraviolet light within the 250-425nm range.
The lens's geometry is characterized by a 2.04mm edge thickness and a 3.42mm center thickness, with an effective focal length (EFL) of 125mm. The front surface of the lens has a radius of curvature (R1) of 57.3mm, and a back focal length (BFL) of 122.65mm. The lens is made of fused silica, a material with a high transmission range and excellent thermal stability, making it suitable for a wide range of applications.
The 48-287 is a spherical lens with a base shape of a circle. It is designed to be used in systems where the object distance is greater than the focal length, resulting in a real, inverted image. This lens is ideal for applications that require UV filtration, such as UV curing, UV spectroscopy, and UV imaging.
