A110-C 7.2 mm Dia. H-LAK54 Molded Glass Aspheric Lenses; EFL=6.24 mm; NA=0.4 AR 1050-1620nm

The A110-C is a high-quality aspheric lens, precision-molded from H-LAK54 glass, a type of crown glass known for its excellent transparency and low auto-fluorescence. This lens boasts a diameter of 7.2 mm and a thickness of 3.78 mm at the edge, making it a compact yet robust optical component.

The lens's effective focal length (EFL) is 6.24 mm, which is a crucial parameter for determining the lens's magnification power. The EFL, combined with the lens's numerical aperture (NA) of 0.4, allows for a wide field of view and high light-gathering capability, making it suitable for various applications.

The A110-C's aspheric design is a significant advantage over traditional spherical lenses. Aspheric lenses reduce spherical aberration, a common optical issue that can degrade image quality. This lens's front and back surfaces are defined by high-order polynomial equations, enabling superior image quality across the entire field of view.

The lens is coated with a broadband anti-reflection coating, optimized for the 1050-1620nm wavelength range. This coating reduces surface reflections, improving transmission and minimizing ghosting and flare.

The A110-C is available from Thorlabs, a leading vendor in the optical components industry. According to the vendor's website, the lens is currently in stock, ensuring quick delivery for your optical system needs.
