LC2265-B 12.7 mm Dia. N-SF11 Plano-Concave Lens; EFL=-15mm 650-1050nm

The LC2265-B is a Plano-Concave Spherical Lens with a diameter of 12.7 mm, manufactured by Thorlabs. This lens is designed for use in the wavelength range of 650-1050nm, making it suitable for a wide range of optical applications. The lens features an effective focal length (EFL) of -15mm, indicating its concave design.

The lens is made from N-SF11 Schott glass, a high-index material often used in high-performance optical systems. The front and back surfaces of the lens are coated with THo BBAR, a broadband anti-reflection coating that reduces surface reflections and increases transmission.

The lens has a center thickness of 3mm and a clear aperture, with no inner or outer radius specified. This suggests that the lens is designed for use with collimated beams. The lens's geometry and material properties make it suitable for use in applications such as laser systems, beam shaping, and imaging.

According to the vendor's website, the lens is currently in stock, indicating its availability for immediate purchase and use. The website also provides further technical specifications and application notes, which may be useful for those considering this lens for their optical system.
