LA1002-A N-BK7 Plano-Convex Lens; Dia:75.0 mm; f=150.0 mm ARC 350-700nm

The LA1002-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 glass, a popular material known for its excellent optical properties and high damage threshold. The lens has a diameter of 75.0 mm and a focal length of 150.0 mm, making it suitable for use in systems where a long focal length is required.

The lens features an anti-reflection coating, designed to reduce surface reflections and increase transmission in the 350-700nm spectral range. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in a variety of lighting conditions.

The geometry of the lens is carefully controlled, with a thickness at the edge of 3.0 mm and a thickness at the center of 12.7 mm. This ensures that the lens performs as expected, with a back focal length of 141.1 mm and an effective focal length of 150.0 mm. The lens is spherical in shape, with a radius of curvature of 77.3 mm on the curved (convex) surface.
