This is a Plano-Concave Lens from Standa, a renowned vendor in the optical industry. The lens, which is part of the spherical lens category, is designed with a base shape of a circle and is uncoated. The lens's primary purpose is to diverge light, making it ideal for various applications where beam expansion is required.
The lens has a diameter of 12.7 mm and a thickness at the edge of 3 mm. The center thickness is 2.6 mm, and the effective focal length (EFL) is -100 mm. The radius of curvature (R1) is -47.61 mm, while the inner and outer radii are 0 mm. These specifications make the lens suitable for use in systems where a concave lens is required.
The lens is made from UVFS Mal- 1965, a material specifically designed for optical applications. It is optimized for use with a wavelength of 355 nm. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in optical systems.
Please note that the lens is uncoated. This means that it does not have any additional layers to protect the surface or modify its optical properties. This may affect the lens's performance in certain applications, particularly those involving high-intensity light or aggressive environmental conditions.
