GL16 – AiO Interferometer





End Face Geometry Measurement Instrument


Using the latest technology in precision optics, high-speed cameras, programming, and touch screen display, Norland Products has developed the GL16 – AiO End Face Geometry Measurement Instrument. This instrument is designed as the ultimate tool for analyzing the end face geometry of single and multifiber connectors, and includes support for recent industry developments such as 16- and 32-fiber MT product and Geometry Limit parameter. The Norland GL16 system achieves accuracy, repeatability, reliability, and ease of use that far exceeds the requirements of the industry for this type of quality control instrument.

Everything has been fully automated in this compact system. All electronics and software for calculation and control is contained within the instrument, so an external computer system is no longer required. And with the internal Linux operating system, there is no need for constant updates or virus protection software, resulting in a much more stable and reliable system.

An Ethernet connection is provided for access to the system measurement data as well as for remote diagnosis and software updates. A USB 3.0 port allows for external mouse, keyboard, or barcode scanner use. There are no operator adjustments necessary or knowledge of interferometry needed. NIST traceable standards provide confirmed calibration of magnification and tilt stage operation, insuring accuracy of all measurements. Our patented True Angle™ connector mounts with integral aperture plate and pins allow easy insertion of the connectors into the mount and provide for highest accuracy, specifically, of surface angle results.
