Measuring & Inspection Systems

Coherent Inc., Santa Clara, Calif., recently enhanced its series of large-area, high-speed PowerMax-Pro laser detectors to enable power measurement of laser beams of up to 375W continuously, 600W for shorter durations, and modulated peak powers as high as 15 kW in intermittent (long-pulse) operation, according to the company. The PowerMax-Pro detectors, introduced in 2014, are based on Coherent’s proprietary thin-film sensor technology that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode.

Perceptron Inc., Plymouth, Mich., recently launched a full range of 5-axis coordinate measurement machines (CMMs) complete with the Renishaw® REVO-2 scanning probe and a fully-integrated universal CMM controller and MODUS® metrology software. The company combined the metrology stability of the COORD3 Universal CMM with the latest Renishaw REVO-2 5-axis measuring system, according to Perceptron CMM Product Sales DirectorElliott Mills. This combination, he added, minimizes CMM dynamic error for high-speed probe motion because all of the part feature scanning motion takes place within the head of the REVO-2, which is said to be the only scanning system for CMMs that simultaneously controls the motion of three CMM and two probe head axes. At the same time, the company added, the REVO-2 also collects workpiece data using its range of 3D tactile probes, surface roughness measurement probe and non-contact vision probe.

To help companies meet tolerances and achieve repeatability, Advanced Industrial Measurement Systems (AIMS), a maker of coordinate measuring machines (CMM), recently introduced the Revolution Series HB Shop Floor CMM, the Dayton, Ohio-based company announced in a Jan. 22 news release. Designed and built around Renishaw 5-axis technology, the Revolution HB is said to be the only mobile 5-axis CMM on the market.

Mahr Federal, Providence, R.I., recently introduced an "entry level" surface finish and contour measuring system capable of generating both surface and contour measurements in a single pass, according to a company news release issued Jan. 21. The MarSurf® UD 130, which replaces the MarSurf UD 120, is said to offer improved nanometer range measurements, high measuring and positioning speeds, a biomimetic probe design with better rigidity and higher dynamics, as well as automatic probe arm recognition.

Hexagon Manufacturing Intelligence, formerly Hexagon Metrology, recently unveiled its new, top-of-the-line addition to the ROMER Absolute Arm portable coordinate measuring machine product line—the 77 Series, which the company described as the most accurate ROMER Absolute Arm to date.

"These enhancements improve operations, eliminate restrictions to the working area and allow an extremely precise display of the spindle position," the company said. The new sensor is said to be capable of fast, "math-free" positioning of the spindle axis on the edges of the workpiece, and offers precision of 0.01mm when used with original Haimer probe tips.
