LC2067 9 mm Dia. N-SF11 Plano-Concave Lens; EFL=-9mm Uncoated

The LC2067 is a Plano-Concave Spherical Lens with a 9 mm diameter, sourced from Thorlabs. This lens is designed for use in optical systems that require a negative focal length, with an Effective Focal Length (EFL) of -9 mm. The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces.

The lens's geometry includes a center thickness of 2 mm and a concave radius of -7 mm. The Inner Radius and Outer Radius are both 0, indicating a uniform curvature across the lens's surface. The lens is made from N-SF11 Schott glass, a high-index, low-dispersion material often used in high-performance optical systems.

This lens is suitable for use with light of a wavelength of 587.6 nm. It is circular in shape, making it compatible with a wide range of optical mounts and systems. The uncoated surface of the lens may exhibit some reflectance, which could be a factor to consider depending on the specific application.

Please note that the lens's EFL is negative, meaning it will cause light to diverge rather than converge. This is typical of Plano-Concave lenses and is often desired in certain optical system designs.
