LC2067-B 9 mm Dia. N-SF11 Plano-Concave Lens; EFL=-9mm 650-1050nm
The LC2067-B is a Plano-Concave Spherical Lens with a 9 mm diameter, sourced from 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 -9mm, indicating its concave design.
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 base shape of the lens is circular, and it has a center thickness of 2mm. The lens's geometry also includes an inner radius of 0mm and an outer radius of 0mm.
The LC2067-B is coated with Thorlabs' BBAR coating on both the front and back surfaces. This coating, known as Broadband Anti-Reflection, is designed to reduce reflection and increase transmission over a wide range of wavelengths. The coating also helps to improve the lens's durability and resistance to environmental factors.
