34-173 50mm Dia. x 200mm FL UV Plano-Convex Lens Laser V-Coat 1550nm
The 34-173 is a 50mm diameter, plano-convex lens with a focal length of 200mm, specifically designed for use with a 1550nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from fused silica, a material with the material ID "fused sil mal-1965". This material is chosen for its excellent transparency and low auto-fluorescence, making it ideal for applications that require high precision and clarity. The lens has a center thickness of 7mm and an edge thickness of 3.53mm, providing a robust and durable structure.
The 34-173 features a UV plano-convex geometry, with a radius of curvature of 91.69mm on the convex side. The back focal length is 195.19mm, and both the inner and outer radii are 0mm, indicating a flat surface on the opposite side of the convex curve. The effective focal length (EFL) is 200mm, which is the distance from the lens's principal point to its focal point.
This lens is coated with Edmund Optics' Laser V-Coat, a proprietary coating designed for use with 1550nm lasers. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, resulting in improved efficiency and accuracy.
