Thickness measuring device MPLS-DM series

for medical applicationscontinuousin-line

Product overview
The ChromaLine sensor family from STIL is a non-contact chromatic confocal solution for high-speed line measurements and on-line inspection. The MPLS-DM version provides 180 aligned measuring points across line lengths from 1.34 to 12.85 mm, designed for continuous industrial use with low maintenance requirements.

Description
MPLS-DM delivers high-resolution distance and thickness measurements with measuring frequencies from 200 Hz up to 2 kHz in standard mode and up to 6 kHz with a reduced measuring range. The sensor supports peak-based distance extraction (first/last and intermediate peaks) and thickness calculation from multiple peaks. Integrated optical head uses passive components for industrial reliability.

Benefits

• Versatile non-contact measurement for reflective materials (metals, glass, plastics, coatings, liquids)
• Industrial-grade optical head built with passive components for long service life
• High throughput: up to 360,000 measured points/second at 2 kHz; >1,000,000 points/second at 6 kHz in dedicated applications
• Distance and multi-peak thickness measurement modes
• High axial resolution and low noise for fine surface and thickness control
• SDK and protocol commands for straightforward integration
• Synchronized acquisitions with encoder input for dynamic processes
• Gigabit Ethernet communication for fast data transfer

Applications

• Automotive glass inspection
• Container and packaging glass production
• Electric vehicle industry (battery cell and cover measurements)
• Roll-to-roll and film thickness control (transparent and opaque films, flexible electronics)
• Electronics (PCB) inspection
• Semiconductor wafers (silicon)
• Consumer electronics components
• Medical component inspection
• Micromechanics and precision engineering
• Aerospace surface and assembly inspection
• Watchmaking and microassembly
• Robotics integration for automated inspection

Versions
ChromaLine sensors are available in five standard MPLS-DM variants: NANOVIEW, MicroView, WireView, DeepView mk2 and SuperView, each optimized for line length and measurement range.
