The 5722-A-H Aspheric Objective Lens is made with D-ZLaF52La. It is 6.3 mm diameter with 40x magnification 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 3.08 mm. It is AR coated for the wavelength range of 350 to 700 nm. This compact glass plano-convex 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. A model 5709 RMS threaded adapter is required for use as a microscope objective. A model 5708 optical mount adapter allows these objectives to be mounted in a 1 inch diameter optical mount.
