LA1979-C N-BK7 Plano-Convex Lens; Dia:2 in; f=200.0 mm ARC 1050-1700nm
The LA1979-C is a Plano-Convex lens, a type of spherical lens, sourced from Thorlabs, a renowned optical components manufacturer. This lens boasts a diameter of 2 inches, or 50.8 millimeters, and a focal length of 200 millimeters, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a thickness of 3 millimeters at the edge and 6.2 millimeters at the center, providing a solid structure for precise optical performance.
The LA1979-C is coated with a broadband anti-reflection coating, specifically designed for the wavelength range of 1050 to 1700 nanometers. This coating reduces unwanted reflections, enhancing the transmission of light through the lens, thereby improving the overall system performance.
