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 3 mm, while the thickness at the center is 7.3 mm. The effective focal length (EFL) of the lens is 50 mm.
The lens is made from CAF2 (Calcium Fluoride) material, specifically identified as "caf2 mal-1963". This material is known for its excellent optical properties, making it suitable for a wide range of applications. The lens is designed to operate at a wavelength of 2940 nm.
Notably, this lens does not come with any coating, as indicated by the empty "coating" parameter in the item data. Coatings are often applied to lenses to enhance their performance or protect them from environmental factors, but this particular lens is uncoated.
The lens's geometry, including its inner and outer radii, is also provided in the item data. The inner radius is 0, and the outer radius is also 0, indicating a simple plano-convex design.
