LA1978-C N-BK7 Plano-Convex Lens; Dia:1 in; f=750.0 mm ARC 1050-1700nm
The LA1978-C is a plano-convex lens offered by Thorlabs, designed for use in the 1050-1700nm wavelength range. This lens is fabricated from N-BK7 Schott glass, a popular material for its high refractive index and low dispersion, making it suitable for a wide range of optical applications.
The lens has a diameter of 1 inch (25.4mm) and a focal length of 750mm, providing a large field of view and high image quality. The plano-convex design features a flat front surface and a curved back surface with a radius of curvature of 386.3mm. This design allows for efficient light collection and focusing, making it ideal for imaging and beam shaping applications.
The LA1978-C is coated with Thorlabs' Broadband Anti-Reflection coating, which is designed to reduce surface reflections and increase transmission across the 1050-1700nm wavelength range. This coating ensures high-quality performance and reduces the need for additional anti-reflection components in your optical system.
The lens has a central thickness of 2.2mm and an edge thickness of 2mm, providing robustness and durability. The lens is also available with a variety of mounting options to suit your specific application needs.
