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 2.5 mm, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is 350 mm.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens is designed to operate at a wavelength of 546 nm. The inner and outer radii of the lens are 0 mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is 180.845 mm.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance in specific applications, such as reducing reflection, increasing transmission, or providing scratch resistance. However, this lens, in its uncoated form, offers a more basic, cost-effective solution.
The lens data suggests that it is in stock and available for immediate use.
