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 variety of optical applications.
The lens has a diameter of 38.1 mm and a thickness at the edge of 2.5 mm. The thickness at the center of the lens is 8.6 mm, providing a substantial depth for light to pass through. The effective focal length (EFL) of the lens is 75 mm, a critical specification that determines the lens's focusing power.
The lens is made from UVFS Mal- 1965, a material specifically designed for use in optical systems. It is optimized for use with a wavelength of 355 nm, making it suitable for applications that involve ultraviolet light.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing protection against environmental factors. However, this lens is in its bare form, offering a simple, unaltered optical surface.
