This is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor, Standa. The lens is characterized by its circular base shape and is designed for use in a wide range of optical applications.
The lens has a diameter of 38.1 mm and a thickness at the edge of 3.9 mm. The thickness at the center of the lens is 4 mm, providing a robust structure suitable for various optical setups. The effective focal length (EFL) of the lens is 3000 mm, making it suitable for long-range optical systems.
The lens is made from UVFS Mal- 1965, a material specifically designed for use in optical applications. It is optimized for use with a wavelength of 355 nm, making it ideal for applications in the ultraviolet spectrum.
Notably, this lens is uncoated. While coatings can be applied to lenses to enhance their performance in specific applications, this lens is designed to provide optimal performance in its uncoated state. This makes it a versatile choice for a wide range of optical applications.
