LC1120-C N-BK7 Plano-Concave Lens; Dia:1 in; f=-100.0 mm ARC 1050-1700nm
The LC1120-C is a plano-concave lens from Thorlabs, designed with a base shape of a circle and constructed from N-BK7 Schott glass. This lens is part of Thorlabs' extensive catalog of optical elements, offering users a high-quality, reliable choice for their optical systems.
The LC1120-C has a diameter of 1 inch (25.4 mm) and a thickness at the edge of 5.6 mm, while its center thickness measures 4 mm. The lens' effective focal length (EFL) is -100 mm, and its front radius of curvature (R1) is -51.5 mm. The back focal length (BFL) is -102.6 mm, and the lens does not have an inner or outer radius.
This lens is designed to work with a wavelength of 587.6 nm and features anti-reflection (AR) coating on both the front and back surfaces, tailored for the 1050-1700 nm range. This coating helps minimize surface reflections, ensuring optimal performance and reducing the need for additional coatings or adjustments.
