LA1134-A N-BK7 Plano-Convex Lens; Dia:1 in; f=60.0 m ARC 350-700nm
The LA1134-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, is designed with a diameter of 1 inch (25.4 mm) and a focal length of 60 meters, making it suitable for a wide range of applications.
The lens's geometry is characterized by its edge thickness of 2 mm and center thickness of 4.7 mm. The effective focal length (EFL) is 60 mm, and the radius of curvature (ROC) of the curved surface is 30.9 mm. The back focal length (BFL) is 56.7 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the opposite side of the curved face.
The lens is coated with a broadband anti-reflection coating, denoted as "tho a bbar," which is applied to both the front and back surfaces. This coating is designed to operate within the wavelength range of 350-700 nm, reducing surface reflections and improving transmission.
