LP11-12-30 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-30mm Uncoated
This is a Plano-Concave lens from CeNing Optics, featuring a 12.7 mm diameter and a center thickness of 2 mm. The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties and wide transparency range. The lens has an effective focal length (EFL) of -30 mm, making it suitable for applications that require a diverging lens.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other. The curvature of the concave surface is represented by a radius of -15.56 mm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While uncoated lenses can be more cost-effective, they may be more susceptible to issues such as surface reflections and reduced transmission.
This lens is designed for use at a wavelength of 546.1 nm. It's important to note that the performance of the lens can vary depending on the wavelength of the light it's used with.
