38-625 25.4mm Dia. x 50mm FL; Uncoated; Laser Grade PCX Lens
This is a 25.4mm diameter, 50mm focal length Plano-Convex (PCX) lens, sourced from the reputable vendor Edmund Optics. The lens is uncoated and boasts a high-quality UVFS MAL-1965 material, making it an excellent choice for laser applications.
The lens's geometry is meticulously designed, with a 2.35mm edge thickness and a 6.35mm center thickness. Its effective focal length (EFL) is 50mm, and the radius of curvature (R1) is 23.8mm. The back focal length (BFL) measures 45.71mm, and both the inner and outer radii are 0mm, indicating a flat surface on the concave side.
The lens is designed to operate at a specific wavelength of 587.6nm, making it suitable for applications that require high precision at this wavelength. The lens's shape is spherical, a common choice for its ease of manufacturing and good optical performance.
Please note that the lens is uncoated, which may affect its performance in certain applications. However, this also means that the lens is more cost-effective and can be a good choice for applications where coating is not necessary or desirable.
