LA1472-C N-BK7 Plano-Convex Lens; Dia:9.0 mm; f=20.0 mm ARC 1050-1700nm
The LA1472-C is a high-quality Plano-Convex lens, sourced from the renowned optical components manufacturer, Thorlabs. This lens, with a diameter of 9.0 mm, is designed for use in the 1050-1700nm wavelength range, making it suitable for a wide range of applications in the infrared spectrum.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties, high damage threshold, and chemical resistance. The Plano-Convex geometry, where one side is flat and the other is curved, is a common choice for applications that require a well-defined focal point.
The LA1472-C has a focal length of 20.0 mm, which is the distance from the lens center to the focal point. This, combined with the 9.0 mm diameter, gives the lens a high numerical aperture, allowing for efficient light collection and focusing.
The lens features anti-reflection coatings on both the front and back surfaces, designed to reduce surface reflections and increase transmission in the 1050-1700nm range. This coating enhances the lens' performance, particularly in applications where low loss and high transmission are critical.
