LC2067-C 9 mm Dia. N-SF11 Plano-Concave Lens; EFL=-8.9mm 1050-1700nm
The LC2067-C is a Plano-Concave Spherical Lens, sourced from the reputable optical components manufacturer, Thorlabs. This lens boasts a 9 mm diameter and a center thickness of 2 mm, making it a compact and efficient optical solution. The effective focal length (EFL) of this lens is -8.9 mm, indicating its concave nature, which is ideal for diverging light paths.
The lens is crafted from N-SF11 Schott glass, a material known for its excellent optical properties, particularly within the wavelength range of 1050-1700 nm. This makes the LC2067-C particularly suitable for applications in the near-infrared spectrum.
The lens features a broadband anti-reflection coating, denoted as 'tho c bbar' on both the front and back surfaces. This coating is designed to minimize surface reflections, thereby enhancing transmission and improving overall system performance.
