LC1611-C N-BK7 Plano-Concave Lens; Dia:2 in; f=-150.0 mm ARC 1050-1700nm
The LC1611-C is a plano-concave lens made from N-BK7 Schott glass, sourced from the reputable vendor Thorlabs. This lens is designed for use within a broad wavelength range of 1050-1700nm, making it suitable for a variety of applications in the near-infrared spectrum.
The lens features a diameter of 2 inches (50.8mm) and a thickness of 8.3mm at the edge, tapering down to 4mm at the center. This plano-concave design, characterized by a spherical shape with one flat and one curved surface, results in a back focal length (bfl) of -152.6mm and an effective focal length (efl) of -150mm. The inner and outer radii are both 0mm, indicating a symmetrical curvature.
The LC1611-C is coated with Thorlabs' proprietary broadband anti-reflection coating (tho c bbar), which is applied to both the front and back surfaces. This coating reduces surface reflections, thereby enhancing transmission and improving overall system performance.
