67-948 25mm Dia. x 250mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 266nm
This 67-948 laser grade plano-convex lens, sourced from Edmund Optics, is a high-quality optical component designed for use with a wavelength of 266nm. The lens boasts a diameter of 25mm and a focal length of 250mm, making it suitable for a wide range of applications.
The lens is constructed from fused silica, a material with a high damage threshold and excellent transmission properties in the ultraviolet region, ensuring optimal performance and longevity. The base shape of the lens is circular, and it features a plano-convex geometry, with a center thickness of 2.71mm and an edge thickness of 2.03mm. The effective focal length (EFL) of the lens is 250mm, and the radius of curvature (R1) is 114.61mm.
The lens is coated with a laser-grade V-coat, specifically designed for use at 266nm. This coating enhances the lens's performance by reducing surface reflections and improving transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
In terms of its physical properties, the lens has an inner radius of 0mm and an outer radius of 0mm. The lens is available in stock, as indicated by the "weblink status" field in the item data.
