LA1119-A N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=50.0 mm ARC 350-700nm

The LA1119-A 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 glass type known for its excellent optical properties, and is Schott-manufactured, ensuring a high level of precision and reliability.

The lens has a diameter of 18.0 mm and a focal length of 50.0 mm, making it suitable for use in systems where a long focal length is required. The edge thickness of the lens is 1.8 mm, while the center thickness is 3.4 mm, providing a robust and durable design.

The LA1119-A is coated with a broadband anti-reflection coating, designed to reduce surface reflections and increase transmission in the 350-700 nm range. This makes it ideal for use in systems that require high transmission and low loss, such as imaging systems, spectroscopy, and beam shaping applications.

The lens is spherical in shape, with a radius of curvature of 25.8 mm on the convex side. This shape, combined with the high-quality glass and precise manufacturing, ensures excellent optical performance, with low distortion and high resolution.
