Profile: Data Optics, Inc. specializes in precision optical research equipment & optical test instruments and supplies. Our product line includes mounting & positioning equipment, spatial filters, microscope objective lenses, precision pinholes & air slits, environmental isolation enclosures, active fringe control system, linear & rotary motion stages. Our mounting & positioning equipment is equipped with data optics system, remote focusing, carriers, V-rod & rod mounts, benches, table rails & alignment bars. Our microscope objective lenses are used with spatial filters and beam expanders are available individually in powers of 5X, 10X, 20X, 40X, 60X and 100X, or as a set. These objective lenses have been proven in major research laboratories to be of superior quality for spatial filtering. They can also be used in spatial filters from other manufacturers as well. Our microscope objective lenses are available in standard and DIN styles, and with combinations of magnification power, aperture size, working distance and focal lengths specifically designed to accommodate the most desired combinations of specification parameters. Their all glass achromatic design with AR coatings, and a wide range of magnifications, enable them to be used in a wide range of scientific applications such as spatial filters, fiber-optic couplers and relay applications.
