This is a Plano-Convex Lens, a type of spherical lens, sourced from Standa. The lens has a circular base shape and is designed for use with a wavelength of 2940 nm. The lens is uncoated, which means it does not have any additional layers to alter its optical properties.
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, at 2.2 mm. The effective focal length (EFL) of the lens is 200 mm. The radius of curvature (R1) is 83.654 mm, while the inner and outer radii are both 0 mm.
This lens is made from CAF2 (Calcium Fluoride), which has the Mal-1963 material ID. The lens is a great choice for applications that require a high level of precision and clarity, given its spherical shape and the material it is made from.
