Michelson (2.5X and 5X) and Mirau (10X, 20X and 50X) Objectives Available? Infinity Corrected 200mm Tube Lens DesignInterferometry objectives are used in non-contact optical profile measurement devices to obtain surface maps and surface measurement parameters. They can be used to examine surface topography with very high precision—to within a fraction of the wavelength of light. In these objectives, a light beam passes through a beamsplitter, which directs the light to both the surface of the sample and a built-in reference mirror. The light reflected from these surfaces recombines and a fringe interference pattern is formed. The Michelson objectives provide comparatively longer working distances, wider fields of view and larger depth of focus, whereas the Mirau objectives are used in applications requiring higher magnification and/or numerical apertures. Use of the Nikon 200mm tube lens (#58- 520) allows these objectives to be integrated to a C-Mount camera.Magnification 2.5X 5X 10X 20X 50X 100xNumerical Aperture 0.075 0.13 0.30 0.40 0.55 0.7Working Distance 10.3mm 9.3mm 7.4mm 4.7mm 3.4mm 2mmFocal Length 80.0mm 40.0mm 20.0mm 10.0mm 4.0mm 2mmResolving Power 3.7μm 2.1μm 0.92μm 0.69μm 0.50μm 0.40μmDepth of Focus 48.6μm 416.2μm 3.04μm 1.71μm 0.90μm 0.56μmField of ViewEyepiece, 25 Diameter Field 10.0mm 5.0mm 2.5mm 1.25mm 0.50mm 0.25mmEyepiece, 20 Diameter Field 4.4mm 2.2mm 2mm 1mm 0.22mm 0.2mm2/3" Sensor Camera (H x V) 3.52 x 2.64mm 1.76 x 1.32mm 0.88 x 0.66mm 0.44 x 0.33mm 0.18 x 0.13mm 0.011 x 0.08mm1/2" Sensor Camera (H x V) 2.56 x 1.92mm 1.28 x 0.96mm 0.64 x 0.48mm 0.32 x 0.24mm 0.13 x 0.10mm 0.08 x 0.06mmWeight 440g 280g 125g 130g 150g 200g商品名称2.5X Nikon CF IC Epi Plan TI Interferometry Objective5X Nikon CF IC Epi Plan TI Interferometry Objective 10X Nikon CF IC Epi Plan DI Interferometry Objective 20X Nikon CF IC Epi Plan DI Interferometry Objective50X NIKON CF IC Epi Plan DI Interferometry Objective100X Nikon CF IC Epi Plan DI Interferometry Objective
