Surface Profiling Sensor uses interferometric technology.

Press Release Summary:

Used for surface contour measurement, TeleStar® Probe scans up to 500 data points/sec with 1.0 micron accuracy and 0.1 micron repeatability. This self-contained, off-axis, partial coherence interferometric range sensor, offering measured point resolution in sub-micron (< 0.1 micron) range, has 25 mm constant working distance and is compatible with specular and light-scattering diffuse surfaces. Return angle allows measurement deep inside bores and blind holes.

OGP® Introduces New High Resolution Surface Profiling Sensor

OGP® (Optical Gaging Products), a division of Quality Vision International (QVI®), introduces its TeleStar® Probe high resolution surface profiling sensor. TeleStar Probe is the newest of many specialized sensors available for OGP multisensor dimensional measurement systems.

TeleStar Probe is a self-contained off-axis partial coherence interferometric range sensor for surface contour measurement. It offers measured point resolution in the sub-micron (< 0.1 micron) range, and provides excellent performance on both specular and light-scattering diffuse surfaces. The probe is fast and accurate, quickly scanning up to 500 data points per second with 1.0 micron accuracy and 0.1 micron repeatability. TeleStar Probe features a 25 mm constant working distance, and its shallow return angle allows measurement deep inside bores and blind holes. TeleStar Probe is mounted in a mechanical deployment mechanism that retracts it out of the way when not in use.

TeleStar Probe uses the same advanced interferometric technology available previously only on OGP SmartScope® Quest, and makes it now available on OGP’s more cost-effective SmartScope ZIP® Advance product line, significantly enhancing ZIP Advance sensor capability and measurement versatility. TeleStar Probe may be specified as an optional sensor for new SmartScope ZIP Advance orders, or it may be retrofitted onto existing ZIP Advance systems.

TeleStar Probe is compatible with QVI ZONE3®, MeasureMind® 3D MultiSensor and VMS metrology software platforms. ZONE3, QVI’s premium CAD-based 3D metrology software, features a clear, simple user interface, and its kinematic model simulates the machine, part, fixtures, and measuring sensor, updated in real time. Built-in productivity maximizing tools, integrated GD&T functionality, and visual validation of measurement intent offer speed and power to the measurement process. ZONE3 supports simultaneous use of multiple sensors, making appropriate tools available for complex measurement tasks. ZONE3 represents the state-of-the-art in 3D metrology software.
