LP11-50-300 50.8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-300mm Uncoated

The LP11-50-300 is a Plano-Concave Spherical Lens with a diameter of 50.8 mm and a center thickness of 2 mm. This lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transparency range. The lens has a negative focal length (EFL) of -300mm, making it suitable for applications that require light convergence or divergence.

The lens's geometry is defined by its inner radius of 0 mm and outer radius of 0 mm, indicating a plano surface on both sides. The curvature of the concave surface is represented by a radius of -155.6 mm. This curvature, combined with the lens's material and thickness, contributes to its negative focal length.

The LP11-50-300 is uncoated, meaning it does not have any additional layers to enhance its optical properties. This may result in a higher level of reflection, particularly at the lens's air-glass interfaces. However, uncoated lenses are often more cost-effective and can be suitable for many applications.
