A DRS™ (Digital Range Sensor) Laser Probe on select SmartScope systems provides non-contact, high resolution surface contouring to supplement video measurements.
As one of the sensors supported by OGP multisensor measurement systems, the metrology software integrates DRS laser data points as easily as those gathered by video measurement. Both linear and area scans are easily programmed into automatic measurement routines for accurate measurement of surface contours.
Two DRS laser probes are available, each with its own spot size. Both models have the same 17 mm working distance and are mounted in mechanical deployment mechanisms so they can be retracted when not in use.
There is a special version of the DRS-500 (DRS 500B) that uses a blue laser rather than a red laser. This version can work better on transparent or white parts.
How Does the DRS Laser Work?
The DRS Laser uses laser triangulation to determine surface heights. The surface is illuminated with a small laser spot. Scattered light is collected by a sensor array. Exact positional information is output to the metrology software at selectable data rates and spacing intervals.
DRS Laser | Resolution | Capture Range | Spot Size |
|---|---|---|---|
| DRS-500 | 0.125 µm | 500 µm | 16 - 23 μm |
| DRS-500B | 0.125 µm | 500 µm | 13 - 20 μm |
