LA1207-A N-BK7 Plano-Convex Lens; Dia:0.5 in; f=100.0 mm ARC 350-700nm
The LA1207-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 features a diameter of 0.5 inches (12.7 mm) and a focal length of 100.0 mm.
The lens has a clear aperture of 0.5 inches (12.7 mm) and a thickness of 1.8 mm at the edge, increasing to 2.2 mm at the center. The effective focal length (EFL) is 100.0 mm, and the radius of curvature (ROC) of the convex surface is 51.5 mm. The back focal length (BFL) is 98.2 mm. The lens does not have any inner or outer radius.
The LA1207-A is coated with Thorlabs' AR coating (tho a bbar) on both the front and back surfaces, which enhances its transmission in the 350-700 nm range. This coating reduces surface reflections, improving the overall efficiency and performance of the lens.
This lens is a spherical lens, meaning it has a spherical surface. Spherical lenses are the simplest type of lens and are widely used in various optical systems due to their ease of manufacture and versatility.
