LC2873 9 mm Dia. N-SF11 Plano-Concave Lens; EFL=-18mm Uncoated
The LC2873 is a Plano-Concave Spherical Lens with a 9 mm diameter, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in the visible light spectrum, specifically at a wavelength of 587.6 nm.
The lens features a concave surface with a radius of curvature (R1) of -14 mm, and a flat surface, also known as plano surface. The effective focal length (EFL) of this lens is -18 mm, which indicates that it is a diverging lens, causing parallel rays of light to spread out. This makes it suitable for applications such as beam expansion or divergence.
The lens is made from N-SF11 Schott glass, a high index of refraction material, which is known for its excellent optical properties. The lens has a center thickness of 2.5 mm, and it does not come with any coating, as indicated by the empty 'coating' field in the item data.
The lens is currently in stock and available for purchase through the Thorlabs website, as indicated by the 'weblink status' field in the item data. For more detailed information, you can refer to the vendor's product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=LC2873.
