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 12.7 mm and a thickness at the edge of 2 mm. The thickness at the center is slightly more, measuring 2.5 mm. The effective focal length (EFL) of the lens is 100 mm. The radius of curvature (R1) is 41.827 mm, while the inner and outer radii are both 0 mm.
The lens is made from CAF2 (Calcium Fluoride) material, specifically the variant mal-1963. This material is known for its excellent optical properties, making it suitable for use in various applications. The lens is designed to operate at a wavelength of 2940 nm.
Notably, this lens does not have any coating. Coatings are often applied to lenses to enhance their optical properties or protect them from environmental factors. However, this lens is uncoated, which may be suitable for certain applications where a specific coating is not required.
The lens is currently in stock and more information about it can be found on Standa's website.
