| Grid and Dot Arrays | ||
 These precision English and Metric Grid and Dot Arrays are manufactured from Select Soda Lime Glass and are furnished with a Certificate of Accuracy with N.I.S.T Traceability. They are ideally suited for set up and calibration of Optical and other Two Dimensional X-Y Stages and Measurement Systems. When built into our Air Cooled Light Boxes and used in conjunction with our MicroRules or MicroScales they provide a complete solution for measurement of photoplotted images, phototooling and two dimensional parts and features. They can also be built into OEM pattern generation and measurement equipment and used with Optical and X-Ray Machine Vision Systems for “on-the-fly” X-Y location and calibration. Grid and Dot Patterns can be chrome on clear glass, low reflection chrome on clear glass, or etched into the clear glass and filled with MIL-I-43553 black (standard), white or red Epoxy. Composite Grid and Dot patterns, with high contrast low reflection black chrome against a diffuse white background, are provided for Machine Vision Applications using top “Thru-the Lens” and “Ring” lighting. Special high density “Doughnut” Dot Arrays are available for X-Ray Imaging and Inspection Systems. Proprietary etched Grid Patterns transparent to top and bottom lighting but visible with edge lighting and fluorescent patterns for deep UV applications are also available through our Sales Engineering Department. Grid and Dot Arrays are available with and without protective edge frames. When edge frames are selected precision plastic glass support disks are provided to maintain the glass flatness for use of the pattern as a calibration source. A carrying case is also provided to protect the Grid or Dot Array during storage. In addition to the standard “Certificate of Accuracy” with NIST Traceability, any Grid or Dot Array can be individually calibrated to provide “Certified Calibration” Traceable to N.I.S.T. | ||
