LA1207-B N-BK7 Plano-Convex Lens; Dia:0.5 in; f=100.0 mm ARC 650-1050nm

The LA1207-B 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, has a diameter of 0.5 inches (12.7 mm) and a focal length of 100.0 mm. The lens's geometry includes an edge thickness of 1.8 mm and a center thickness of 2.2 mm, providing a robust structure for various applications.

The lens's front and back surfaces are coated with ARC 650-1050nm, a broadband anti-reflection coating that reduces reflection and increases transmission across the 650-1050nm wavelength range. This coating enhances the lens's performance in infrared applications, making it suitable for use in systems like optical imaging, beam shaping, and laser applications within this spectral range.

The lens's shape is spherical, with a radius of curvature (r1) of 51.5 mm and a back focal length (bfl) of 98.2 mm. This shape ensures a wide field of view and low distortion, making the LA1207-B an excellent choice for various optical systems.
