LP11-50-500 50.8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-500mm Uncoated
This is a Plano-Concave Spherical Lens, sourced from CeNing Optics, with a circular base shape and a diameter of 50.8 mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.
The lens has a center thickness of 2 mm and an effective focal length (EFL) of -500 mm, making it a high-powered negative lens. The radius of curvature (R1) is -259.4 mm, indicating a strongly curved concave surface. The lens does not have any coating, as indicated in the item data.
This lens is suitable for applications that require strong negative power and a large aperture. The uncoated surface may introduce some reflective losses, but it can also be beneficial in certain applications where anti-reflection coatings are not desired.
Please note that the lens is in stock and available for immediate purchase, as indicated by the "weblink status" in the item data. For more information, you can refer to the vendor's website through the provided weblink.
