The 5721-A-H Aspheric Lens is made with Corning C0550 with 4.0 mm diameter and has focal length of 2.8 mm. This aspheric lens has a housing length of 11.8 mm with 3.6 mm clear aperture and a working distance of 1.6 mm. It is AR coated for the wavelength range of 375 to 650 nm. This compact glass aspheric lens is a convenient, high-quality alternative to microscope objectives. It is especially handy for low f-number applications like coupling light into and out of optical fibers or collimating diode lasers since the aspheric surface minimizes the aberrations.
