ACL3026U-B ø30 mm Aspheric Condenser Lens; f=26 mm, NA=0.55 AR 650-1050nm
The ACL3026U-B is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a catalog number of ACL3026U-B and is available for purchase directly from the Thorlabs website, where it is currently in stock.
The lens is constructed from b270 Schott glass, a material known for its excellent optical properties. It has a diameter of 30 mm and a thickness at the edge of 2.1 mm. The effective focal length (EFL) of the lens is 26 mm, and it has a numerical aperture (NA) of 0.55.
The ACL3026U-B features an aspheric surface with a radius of curvature of 13.551 mm on the front side and a flat surface on the back side. The back focal length (BFL) is 18 mm, and the thickness at the center is 11.9 mm. The lens's surface irregularity is less than λ/10 at 633 nm, and its surface quality is 60-40 scratch-dig.
The lens is coated with a broadband anti-reflection coating, suitable for wavelengths between 650 nm and 1050 nm. This coating reduces surface reflections and increases the lens's transmission efficiency.
