Test & Measurement<br />
Non-contact “Line” Sensors in the visible range<br />

The MPLS180 is the first “line” chromatic confocal sensor on<br />
the market. lt projects on the sample surface a “line” constituted<br />
of 180 discrete points, each corresponding to an independent<br />
measuring channel. The maximum line rate of the<br />
sensor is 1,800 lines/s. Thanks to this very high throughput<br />
the MPLS180 is the ideal tool for online inspection.<br />
Key Features<br />
• Very high throughput (324,000 points/s)<br />
• Data transmission by GigE<br />
• High resolution, high accuracy<br />
• Can measure on any material<br />
• lnsensitive to ambient light<br />
Optical principle<br />
The MPLS180 consists of 180 independent chromatic confocal<br />
channels. Each channel measures a single point on the<br />
surface of the sample, and comprises its own point source,<br />
pinhole and spectrometer. The chromatic lens is common to<br />
all the channels. ln the MPLS180 the controller and the optical<br />
head are connected by two fiber optic bundles. The first bundle<br />
connects the internal light source inside the controller to<br />
the entrance plane of the lens; the tips of the 180 fiber optic<br />
cables in the bundle materialize the point sources of the 180<br />
channels. The second bundle connects the output plane of<br />
the spectrometers; the tips of the 180 fiber optic cables materialize<br />
the pinholes of the 180 channels. The fact that each<br />
point is measured by a separate channel is essential for preventing<br />
“cross talk”; otherwise stated, highly reflecting sample<br />
points do not disturb the measurement of nearlying<br />
points with lower reflectivity.<br />
