LA1708-780 N-BK7 Plano-Convex Lens; Dia:1 in; f=200.0 mm 780nm V-Coat

The LA1708-780 is a high-quality Plano-Convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7, a popular optical glass due to its excellent optical properties, high homogeneity, and low optical dispersion. The lens has a diameter of 1 inch (25.4 mm) and a focal length of 200.0 mm at a wavelength of 780 nm.

The Plano-Convex design of this lens, where one side is flat and the other is curved, provides a number of advantages. It minimizes spherical aberration, a common issue in optical systems, and focuses light to a tight spot, increasing the intensity of the beam. The lens has a front thickness of 2 mm and a center thickness of 2.8 mm, providing excellent durability and resistance to damage.

The LA1708-780 is coated with Thorlabs' V-Coat, a broadband anti-reflection coating designed for high performance across a wide range of wavelengths. This coating reduces surface reflections, improving transmission and enhancing the overall performance of the lens. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in both transmission and reflection.
