LC2632 6 mm Dia. N-SF11 Plano-Concave Lens; EFL=-12mm Uncoated
The LC2632 is a Spherical Lens with a Plano-Concave base shape and a circular geometry. Sourced from Thorlabs, this lens has a diameter of 6 mm and a center thickness of 2 mm. The effective focal length (EFL) is -12 mm, indicating that it is a diverging lens, often used to spread light. The inner and outer radii are both 0, and the lens is made from n-SF11 Schott, a high-index glass with excellent transmittance in the visible and near-infrared regions.
The lens is designed to operate at a wavelength of 587.6 nm, which is in the green part of the visible spectrum. It is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can result in higher reflective losses, but it also means that the lens is less susceptible to damage from environmental factors or cleaning.
The LC2632 is available from Thorlabs and is currently in stock. For more information, including technical drawings and specifications, please refer to the product webpage linked below.
