ACL2520U-B ø25 mm Aspheric Condenser Lens; f=20.1 mm, NA=0.60 AR 650-1050nm
The ACL2520U-B is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a catalog number of ACL2520U-B and is available for purchase directly from 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 25 mm and a thickness at the edge of 2.8 mm. The effective focal length (EFL) of the lens is 20.1 mm, and it has a back focal length (BFL) of 12 mm. The thickness at the center of the lens is also 12 mm.
The ACL2520U-B features an aspheric shape, which helps to reduce spherical aberration and improve the overall image quality. The lens has a numerical aperture (NA) of 0.6 and a wavelength of 633 nm. The front and back surfaces of the lens are coated with tho b bbar, a coating that enhances the lens's transmission and durability.
This lens is particularly suitable for use in applications that require a high NA and a long working distance. It is also well-suited for use with lasers and other coherent light sources. The lens's broadband anti-reflection coating, which is effective in the 650-1050 nm range, further enhances its performance in these applications.
