A110-B 7.2 mm Dia. H-LAK54 Molded Glass Aspheric Lenses; EFL=6.24 mm; NA=0.4 AR 650-1050nm

The A110-B is a high-quality aspheric lens, precision-molded from H-LAK54 glass, a type of crown glass known for its excellent transparency and low autofluorescence. This lens boasts a diameter of 7.2 mm and a thickness of 3.78 mm at the edge, making it suitable for a wide range of optical applications.

The lens features an effective focal length (EFL) of 6.24 mm, which is the distance from the lens's principal point to the focal point when the lens is imaging an object at infinity. This EFL value is crucial in determining the lens's magnification and field of view in a system.

The A110-B's aspheric design, characterized by its radii of curvature (r1 and r2) and conic constant (k1), helps correct spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality, particularly in high-power applications.

The lens has a numerical aperture (NA) of 0.4, which quantifies the light-gathering ability of the lens. A higher NA allows for a larger light-gathering angle, resulting in a brighter and sharper image.

The A110-B is coated with a broadband anti-reflection coating, optimized for the 650-1050nm wavelength range. This coating reduces surface reflections, enhancing transmission and improving overall system performance.
