48-669 12mm Dia. x 36mm FL Uncoated; UV Plano-Convex Lens
The 48-669 is a 12mm diameter, 36mm focal length Plano-Convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens, designed for use in the ultraviolet (UV) spectrum, is uncoated, offering a bare, unaltered glass-air interface.
The lens's geometry is characterized by a 1.37mm edge thickness and a 2.5mm center thickness, providing a balanced structure for various applications. The base shape is circular, ensuring uniform light distribution and ease of integration into optical systems.
The lens's material composition is fused silica (mal-1965), a high-quality, low-autofluorescence material, making it an excellent choice for UV applications. The 587.6nm wavelength specification indicates its primary use in the visible light spectrum's middle to near-UV range.
The Plano-Convex design, with a 16.51mm radius of curvature, offers a large, flat surface for easy mounting and alignment. The back focal length of 34.29mm allows for sufficient working distance, ensuring minimal vignetting and optimal light transmission.
