LA1608-A N-BK7 Plano-Convex Lens; Dia:1 in; f=75.0 mm ARC 350-700nm
The LA1608-A is a plano-convex lens from Thorlabs, designed with a spherical surface and a circular base shape. This lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. The lens has a diameter of 1 inch (25.4 mm) and a thickness of 2 mm at the edge, while the center thickness measures 4.1 mm.
The lens's effective focal length (EFL) is 75 mm, making it suitable for a wide range of optical applications. The front and back surfaces of the lens are coated with ARC 350-700nm, a broadband anti-reflection coating that reduces surface reflections and increases transmission in the 350-700 nm wavelength range.
The radius of curvature (R1) of the convex surface is 38.6 mm, and the back focal length (BFL) is 72 mm. The lens does not have an inner radius, and the outer radius is also 0, indicating a flat surface.
This lens is available from Thorlabs and is currently in stock, according to the vendor's website. The detailed information provided here can help users make informed decisions when selecting optical components with similar specifications.
