ACL2018U-A 20 mm Aspheric Condenser Lens; f=18.1 mm, NA=0.52 AR 350-700nm

The ACL2018U-A is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a focal length of 18.1 mm and a numerical aperture of 0.52, making it an ideal choice for a wide range of optical applications.

The lens is crafted from B270 Schott glass, a material known for its excellent optical properties and durability. It features a diameter of 20 mm and a thickness of 1.8 mm at the edge, ensuring robustness and stability. The center thickness of the lens is 8 mm, and it has a back focal length of 13 mm.

The ACL2018U-A is coated with a broadband anti-reflection coating, optimized for the 350-700 nm range. This coating significantly reduces surface reflections, enhancing the overall transmission of the lens and improving the quality of the optical system.

The lens's aspheric design helps to minimize spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality and increased efficiency in the optical system. The lens's front and back surfaces are both aspheric, further enhancing its performance.
