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 various optical applications.
The lens has a diameter of 25.4 mm and a thickness at the edge of 2.4 mm. The center thickness is 4 mm, providing a robust structure for efficient light transmission. The effective focal length (EFL) of this lens is 125 mm, making it suitable for applications that require a longer focal length.
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, making it ideal for applications in the ultraviolet spectrum.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance in specific applications, such as reducing reflection or increasing transmission. However, this lens, in its uncoated form, offers a different set of benefits, such as cost-effectiveness and simplicity.
