48-303 25mm Dia. x 500mm FL; Uncoated; UV Double-Convex Lens
The 48-303 is a 25mm diameter, 500mm focal length uncoated UV double-convex lens, sourced from the reputable optical components vendor, Edmund Optics. This lens is a spherical lens with a convex-convex base shape, contributing to its double-convex design. The lens's circular geometry, with a diameter of 25mm, is complemented by its edge thickness of 3.01mm and center thickness of 3.35mm.
The lens's effective focal length (EFL) is 500mm, making it suitable for applications requiring a longer focal length. The first radius of curvature (R1) is 457.93mm, while the second radius (R2) is -457.93mm, indicating the double-convex nature of the lens. The back focal length (BFL) is 498.85mm. The lens's inner and outer radii are both zero, suggesting a simple, double-convex design.
The lens is made from fused silica, identified as "fused sil mal-1965" in the material ID. This material is known for its excellent transparency in the ultraviolet (UV) region, making this lens ideal for UV applications. The lens is uncoated, which may be suitable for specific applications where coating is not required or preferred.
Please note that the wavelength specified is 587.6nm, which is in the visible light spectrum. However, the lens's UV transparency and the vendor's information suggest that it is designed for UV applications. Always ensure that the lens meets your specific requirements before purchasing.
