LA1908-A N-BK7 Plano-Convex Lens; Dia:1 in; f=500.0 mm ARC 350-700nm

The LA1908-A is a plano-convex lens made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, has a diameter of 1 inch (25.4 mm) and a focal length of 500.0 mm. The lens's design, with a spherical shape and a plano-convex base, allows for efficient light collection and focusing.

The lens's geometry includes a thickness of 2 mm at the edge and 2.3 mm at the center, providing a solid structure for various applications. The effective focal length (EFL) is 500 mm, which, when combined with the lens's diameter, results in a high F-number, indicating a narrow beam of light and increased depth of field.

The lens's front and back surfaces are coated with ARC 350-700nm, a broadband anti-reflection coating that reduces surface reflections and increases transmission in the visible spectrum (350-700 nm). This coating enhances the lens's performance in applications that require high transmission and minimal reflection.

The LA1908-A is available from Thorlabs and is currently in stock, making it an accessible option for those in need of a high-quality plano-convex lens for their optical systems.
