A220 7.2 mm Dia. D-K59 Molded Glass Aspheric Lenses; EFL=11 mm; NA=0.26 Uncoated

The A220 7.2 mm Dia. D-K59 Molded Glass Aspheric Lens is a high-quality optical component sourced from Thorlabs. This lens, with a catalog number A220, is designed for use with a wavelength of 633 nm and features an extensive range of specifications that make it suitable for various applications.

The lens is of the aspheric type, which means it has a non-spherical surface. This design helps to reduce spherical aberration, a common issue in spherical lenses, thereby improving the optical performance. The base shape of the lens is circular, and it has a diameter of 7.2 mm. The edge thickness of the lens is 3.82 mm, while the center thickness is 5 mm.

The lens has an effective focal length (EFL) of 11 mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity. The lens's numerical aperture (NA) is 0.26, which indicates the lens's light-gathering ability and resolution.

The lens is made of D-K59 CGDM glass, a material known for its excellent optical properties. The lens is uncoated, meaning it does not have any anti-reflective or other coatings. However, it is in stock and available for immediate purchase.
