LP11-06-20 6 mm Dia. N-BK7 Plano-Concave Lens; EFL=-20mm Uncoated
This product is a Plano-Concave Spherical Lens, sourced from the reputable vendor CeNing Optics. The lens has a circular base shape and is designed for use in optical systems that require a negative focal length.
The lens has a diameter of 6 mm and a center thickness of 2 mm. The effective focal length (EFL) of this lens is -20 mm, indicating that it will diverge light passing through it. The radius of curvature for the concave surface is -10.37 mm. The inner and outer radii are both 0 mm, suggesting that this lens has a uniform thickness across its diameter.
The lens is made from N-BK7, a popular optical glass type manufactured by Schott. This material is known for its excellent optical properties, making it a common choice for a wide range of optical applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.
The lens is designed to operate at a wavelength of 546.1 nm. This wavelength falls within the visible light spectrum, suggesting that this lens is intended for use in systems that deal with visible light.
