355110-A 7.2 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=6.2 mm; NA=0.4 AR 350-700nm

The 355110-A is a high-quality aspheric lens, precision-molded from D-ZLAF52LA glass, a type of glass known for its excellent optical properties. This lens boasts a diameter of 7.2 mm and an effective focal length (EFL) of 6.2 mm, making it suitable for a wide range of optical applications.

The lens features a high numerical aperture (NA) of 0.4, which allows for a larger light-gathering capacity and improved resolution. The anti-reflection (AR) coating on both the front and back surfaces, designed for the 350-700nm wavelength range, reduces surface reflections and increases transmission, further enhancing the lens's performance.

The lens's geometry is carefully designed with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission. The thickness at the edge is 4.251 mm, while the center thickness is 5.158 mm, providing excellent structural integrity.

The lens's aspheric shape, defined by its radii (r1 and r2), as well as its conic constant (k1), ensures minimal spherical aberration and distortion, providing sharp and clear images. The aspheric coefficients (a2 to a16) further refine the lens's performance, ensuring high-quality imaging even in demanding applications.
