The ZNPX12 is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. It boasts a base shape of a circle and is designed for use in the infrared spectrum, specifically at a wavelength of 10600 nm. This lens is uncoated, which means it does not have any additional layers to enhance or alter its optical properties.
The lens has a diameter of 25.4 mm and a thickness at the edge of 1.5 mm. The center thickness is slightly more, measuring 3.038 mm. The effective focal length (EFL) of this lens is 75 mm, and the radius of curvature (R1) is 105.209 mm. The inner radius is 0 mm, indicating that this lens is solid and does not have a hollow or recessed section.
This lens is made from znse marple-1964, a material specifically designed for optical applications. The lens is available from the vendor's website, and the link provided indicates that it is currently in stock.
