LC2067-A 9 mm Dia. N-SF11 Plano-Concave Lens; EFL=-9mm 350-700nm
The LC2067-A is a plano-concave spherical lens with a 9 mm diameter, sourced from Thorlabs. This lens is designed for use in the ultraviolet to near-infrared spectrum, specifically between 350 and 700 nm. The lens features an effective focal length (EFL) of -9 mm, making it suitable for applications that require a negative focal length.
The lens is made from N-SF11 Schott glass, a high-index, low-dispersion material that is often used in high-performance optical systems. The front and back surfaces of the lens are coated with a broadband anti-reflection coating, denoted as "tho a bbar". This coating is designed to reduce surface reflections and improve transmission across the lens's spectral range.
The lens has a center thickness of 2 mm and a clear aperture, with no inner or outer radii specified. This suggests that the lens is designed for use with collimated beams, where the beam diameter is larger than the lens diameter.
