49-986 9mm Dia. x 36mm FL; Uncoated; UV Double-Convex Lens
The 49-986 is a high-quality double-convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens is characterized by its 9mm diameter and a focal length of 36mm, making it suitable for a wide range of optical applications.
The lens is fabricated from fused silica, specifically from the material ID mal-1965. This material is known for its excellent transmittance across a broad spectrum, including the ultraviolet (UV) range, making this lens particularly useful in UV-based applications.
The lens's geometry is spherical, with a base shape of a circle. The radii of curvature for the first and second surfaces are 32.69mm and -32.69mm, respectively. The center thickness of the lens is 2mm, while the edge thickness is 1.38mm. The back focal length (BFL) of the lens is 35.31mm, and the effective focal length (EFL) is 36mm.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
