LP11-50-100 50.8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm Uncoated
This is a Plano-Concave lens, type of spherical lens, sourced from CeNing Optics. The lens has a circular base shape with a diameter of 50.8 mm and a center thickness of 2 mm. The effective focal length (EFL) of this lens is -100 mm, indicating that it is a diverging lens, causing incoming parallel rays to diverge after refraction.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The wavelength for which this lens is designed is 546.1 nm. The lens does not have any coating, which means it is uncoated. However, it is important to note that uncoated lenses can suffer from reduced transmission and increased reflection, especially at the air-glass interfaces.
The inner and outer radii of the lens are 0, indicating that the lens is plano-concave, meaning one side is flat, and the other side is curved inwards. The curvature of the concave side is defined by a radius of -51.88 mm.
