Absolute Tracker

The Leica Absolute Tracker AT960

Exact Metrology, Cincinnati, OH, offers high-performance laser tracker technology in a portable and easy-to-use form factor.

The Leica Absolute Tracker AT960 is a robust, all-in-one laser tracker that fits in a single flight case. Offering high-speed dynamic measurement as standard, it is a complete solution for six degrees of freedom (6DoF) probing, scanning, and automated inspection as well as reflector measurement.

Featuring wireless communication and a battery operation option, the design of the tracker reduces setup time drastically.

The Leica Absolute Interferometer (AIFM) enables accurate high-speed measurement of a moving target, while the innovative.

The Verifire Asphere+

Zygo, Middlefield, CT, has launched a new laser Fizeau interferometer. The Verifire Asphere+ was made specifically for fast, noncontact, high-resolution 3D metrology of aspheric surfaces. The VFA+ leverages the benefits of Fizeau interferometry through a unique combination of precise, high-resolution, fast, and full aperture metrology for axisymmetric aspheres.

This allows faster convergence on deterministic polishing feedback for more efficient surface generation as well as coverage of form error and midspatial frequency surface characteristics with one instrument. The system is also flexible, with the ability to measure a range of aspheres with only the change of the reference optic.

CMM Laser Sensor

The HP-L-10.10 sensor

A noncontact laser sensor for coordinate measuring machines (CMMs) from Hexagon’s Manufacturing Intelligence, North Kingstown, RI, offers manufacturers the ability to perform dimensional measurements at comparable accuracy to tactile probing and inspect almost any surface in a fraction of the time. The HP-L-10.10 sensor uses the company’s latest cross-platform laser line scanning technology to offer repeatability and performance compared to tactile measurements executed on the same CMM. It can measure 600,000 individual points per second with a probing form error of just 8 μm, rapidly capturing a complete high-resolution digital representation of a part that is valid for both surface and detailed feature inspection.

Snapshot Sensor

The surfaceCONTROL 3D 3500

Micro-Epsilon, Raleigh, NC, has released a snapshot sensor for inline inspection of geometry, shapes, and surfaces. The surfaceCONTROL 3D 3500 works according to the principle of optical triangulation based on fringe projection.

Using a matrix projector, a sequence of patterns is projected onto the surface of the measuring object. The light of the patterns diffusely reflected by the test object surface is recorded by two cameras. The three-dimensional surface of the test object is then calculated from the recorded image sequence and the knowledge of the arrangement of the two cameras to each other.
