LA1978-B N-BK7 Plano-Convex Lens; Dia:1 in; f=750.0 mm ARC 650-1050nm

The LA1978-B is a plano-convex lens from Thorlabs, designed with a spherical surface and a circular base shape. This lens is fabricated from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. 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 2.2 mm. The effective focal length (EFL) of this lens is 750 mm, making it suitable for a wide range of applications.

The lens's front and back surfaces are coated with Thorlabs' BBAR coating, which is optimized for the ARC 650-1050nm wavelength range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a curved surface on the other.

This lens is a versatile optical component, ideal for use in various applications such as imaging systems, beam shaping, and laser applications. The detailed information provided here is intended to assist users in understanding the lens's properties and selecting the most suitable component for their specific needs.
