LD2060-C N-SF11 Bi-Concave Lens; Dia:12.7 mm; f=-15.0 mm ARC 1050-1700nm
The LD2060-C is a high-quality bi-concave lens offered by Thorlabs, a leading vendor in the optical industry. This lens, designed with a spherical shape, is constructed from n-SF11 Schott glass, a material known for its excellent optical properties. The lens features a diameter of 12.7 mm and a thickness of 4.7 mm at the edge, tapering down to 3 mm at the center.
The LD2060-C has a focal length of -15 mm, making it a powerful tool for focusing or diverging light beams. The curvature of the lens is defined by radii of -24 mm and 24 mm for the front and back surfaces, respectively. The back focal length is -15.7 mm, and the lens has no inner or outer radius, indicating a uniform curvature across its surface.
This lens is designed to operate within the wavelength range of 1050-1700 nm, making it suitable for a wide range of applications in the near-infrared spectrum. The lens is coated with a broadband anti-reflection coating (ARC), specifically designed for the wavelength range of 1050-1700 nm, which reduces surface reflections and improves transmission.
