LP11-12-40 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm Uncoated
This is a Plano-Concave lens, a type of spherical lens, sourced from CeNing Optics. The lens has a circular base shape with a diameter of 12.7 mm and a center thickness of 2 mm. The effective focal length (EFL) of this lens is -40 mm, indicating that it is a diverging lens, causing incoming light rays to spread out.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The wavelength for this lens is 546.1 nm. The lens does not come with any coating, which means it is uncoated. However, it is important to note that coatings can be applied to enhance the lens's performance, such as improving its transmission or reducing reflection.
The inner and outer radii of the lens are 0, indicating that it is a simple meniscus lens with equal curvature on both sides. The concave side of the lens has a radius of curvature of -20.75 mm.
This lens is available from CeNing Optics and is currently in stock. For more information, you can refer to the vendor's website provided in the item data.
