LA1119-B N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=50.0 mm ARC 650-1050nm
The LA1119-B is a Plano-Convex lens, a type of spherical lens characterized by having one flat surface and one curved surface. This lens, sourced from the reputable vendor Thorlabs, boasts a diameter of 18.0 mm and a focal length of 50.0 mm, 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 due to its excellent optical properties. This material, also known as Schott glass, is known for its low dispersion and high Abbe number, making it an ideal choice for applications that require high image quality and low chromatic aberration.
The LA1119-B features a broadband anti-reflection coating, specifically designed for the 650-1050nm wavelength range. This coating significantly reduces surface reflections, thereby enhancing transmission and improving overall system performance.
The lens has a thickness of 1.8 mm at the edge and 3.4 mm at the center, providing a robust and durable design. The front and back surfaces of the lens are coated with the same broadband anti-reflection coating, ensuring optimal performance from both sides.
