LA1708-C N-BK7 Plano-Convex Lens; Dia:1 in; f=200.0 mm ARC 1050-1700nm
The LA1708-C is a plano-convex lens, a type of spherical lens, featuring a circular base shape and sourced from the reputable vendor, Thorlabs. This lens is designed for use within the wavelength range of 1050-1700nm, with a central wavelength of 587.6nm, making it suitable for a variety of optical applications.
The lens boasts a diameter of 1 inch (25.4mm) and a thickness of 2mm at the edge, while the center thickness measures 2.8mm. The effective focal length (EFL) is 200mm, and the radius of curvature (ROC) of the curved surface is 103mm. The back focal length (BFL) is 197.5mm, and the inner and outer radii are both 0mm, indicating a plano surface on the opposite side of the curved face.
The LA1708-C is crafted from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens features anti-reflection (AR) coating on both the front and back surfaces, specifically designed to reduce reflection across the 1050-1700nm wavelength range. This coating enhances the lens's performance by minimizing signal loss and improving transmission efficiency.
