NORLAND AC3000 AUTOMATED NON-CONTACT INTERFEROMETER SYSTEM
The Norland AC-3000 is a fully automated, non-contact interferometric microscope designed for measuring the endface geometry of fiber optic surfaces such as connector assemblies, ferrules, and optical fibers. Using a versatile inverted microscope with a built-in camera and a high-speed computer, the AC-3000 provides immediate 3D topographical information on the surface being inspected. Specifically designed to measure the key parameters of PC polished connectors, the AC-3000 measures the radius of curvature, offset of polish, undercut, or protrusion on FC, ST ® , SC, LC, and MU type connectors. In addition, this system can measure APC, flat polished connectors, bare ferrules, cleaved or polished fibers, and sections of multifiber connectors. The feedback from the AC-3000 provides the user with optimum control of the production process by quickly showing any variation in the polish quality. The AC-3000 is a novel system that quickly switches between standard monochromatic phase shift interferometry (PSI) or white light (broadband scanning) interferometry to handle a wide range of surfaces. The monochromatic mode allows the system to quickly map smooth surfaces, while the white light mode uses the latest state-of-the-art technology to measure difficult, rough surfaces and eliminate ambiguities in step heights. This method provides the “True View” that the monochromatic mode cannot always measure. Together, the two modes provide extra versatility for analyzing all types of connectors, for trouble shooting or process development and for measuring fiber protrusion (undercut or push back) up to four microns above or below the ferrule. Designed for users needing extreme accuracy, the AC-3000 is capable of measuring fiber height to ±0.002 microns and radius of curvature and offset of polish to ±0.10 mm and ±1.0 microns respectively. Each unit is supplied with NIST traceable spherical calibration standards to allow the user to certify the accuracy of the measurements. No other system provides the customer with this ultimate assurance of performance. In less than three seconds, the advanced technology of the AC-3000 can obtain the surface topology of a smooth connector. Coupled with a pass/fail function, the AC-3000 quickly converts from a valuable research tool to an indispensable part of a modern quality control system, giving the end user full control of fiber optic connector quality and performance. The AC-3000 with Windows NT operating system is by far the easiest, most user friendly system on the market today. Simply insert a connector into the unit, adjust the focus and analyze; the AC-3000 does the rest and results are clearly displayed on the monitor. Use either the keyboard or the mouse to activate pull down menus, shortcut icons and online and context-sensitive help. Fast print spooling and multiprocessing capabilities allow a hard copy print of the information through a standard ink jet or laser printer. Data can be automatically saved, displayed or printed in Excel for statistical analysis. In addition, custom reports can be generated for each connector with user selectable images and measurement results (bar code labels and reports can be printed on one page). The pressure sensitive label can be affixed to the outside of a patch cord bag. All these data functions are accessed directly in the AC-3000 program. The unit is designed on an extra stable, inverted microscope base for precision and ease of use. Switching from 2.5 mm connectors to 1.25 mm connectors is accomplished in seconds with only two thumb screws. Nothing is faster or simpler. With our new, user-friendly autolevel software, it only takes a minute to calibrate the mount for sub-micron accuracy in offset measurements. The software also prompts the user to replace the mount if wear becomes excessive. Our exclusive “Variable Tilt Stage” allows the instrument to be quickly adjusted for APC measurements. The stage has continuous variable angles from 0 to 13 degrees. A NIST traceable angle standard is available that guarantees accuracy to 0.01 degrees.

Reproducibility based on 100 measurements re-inserting connector between measurements. Repeatability based on 100 measurements without disturbing the connector between measurements. Reproducibility and repeatability reported are the full differential range of all measurements (max -min) with an AC-3000 on a vibration damping table, after autoleveling, using a connector with a 15 mm adius of curvature.
