(NIST) - Optional integrated solder wire feed controller for laser soldering
Information
Mergenthaler, No. 1 in temperature-controlled laser material processing
Dr Mergenthaler high-speed infrared pyrometers are characterised by their accuracy, speed and flexibility. They form a complete system comprising high-speed temperature data acquisition, closed-loop control, visualisation, real-time storage and archiving.
Typical temperature ranges for
Mergenthaler infrared pyrometers:
from 100°C to 2,340°C across various measurement ranges (at 10,000 measurements per second)
For example: 100°C to 560°C, 550°C to 2,340°C
(Special pyrometers from 70°C at lower measurement rates)
Emission coefficient adjustable via software: 0.05 to 1.00
Applications: laser plastic welding, laser brazing, low-temperature measurements on metals
The integrated temperature process controller can be used to control laser sources or induction generators. This makes it easy to optimise the quality of processes that were previously controlled by specifying a processing temperature.
The system operates autonomously: that is, it measures, controls and stores data at a rate of up to 15 kHz without a PC connection. With the LASCON® Process Manager software package, you can visualise , configure and monitor your laser process. Using a simple scripting language, you can programme and execute up to 256 different laser scripts. These scripts enable you to monitor your laser processes 100 per cent and ensuretraceability across your entire production.

With over 1,500 industrial LASCON® installations worldwide, Mergenthaler is the global market leader in temperature-controlled laser material processing.
Applications for the Mergenthaler LASCON® infrared pyrometers include:
Laser plastic welding: In laser plastic welding, LASCON® controls the welding temperature of the seam and ensures a perfect bond that also delivers the best visual result. The system provides 100 per cent monitoring of production and records all key process parameters. It can also be used in conjunction with galvanometer scanners.
Laser brazing: Temperaturemonitoring of the laser brazing process ensures a high-quality brazed joint free from burn-through and voids.
Other applications:
- Temperature measurement on silicon wafers in epitaxial processes under vacuum (from 80°C)
- Temperature measurement of ceramics and crystals (including in a vacuum)
- Control of preheating during thermal bonding
- Control of heating during crystal research in a vacuum
