Aspheric Lens, 6.3 mm, 4.5 mm EFL, AR coated for 1000-1600 nm

The 5722-C-H Aspheric Lens is made with Corning C0550 with 6.3 mm diameter and has focal length of 4.5 mm. This aspheric lens has a housing length of 10.6 mm with 5.0 mm clear aperture and a working distance of 2.9 mm. It is AR coated for the wavelength range of 1000 to 1600 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.
