Mergenthaler, No.1 in temperature controlled laser material processing

Dr. Mergenthaler High Speed ​​Infrared Pyrometers are characterized by their accuracy, speed and flexibility. They form a complete system of high-speed temperature data acquisition, closed-loop control, visualization, real-time storage and archiving.

Mergenthaler Infrared Pyrometer:
from 100°C to 2,340°C in different measuring ranges (at 10,000 measurements per second)
For example: 100°C to 560°C, 550°C to 2,340°C
(Special pyrometer from 70°C at lower measuring rates)
Software adjustable emission coefficient: 0.05 to 1.00

Application: Laser plastic welding, laser soldering, low-temperature measurements on metals

With the integrated temperature process controller laser sources or induction generators can be controlled. In this way, processes that were previously guided by constant laser power can now be optimized simply by specifying a processing temperature.
The system works autonomously: meaning, without PC connection, you can measure, control, store the temperature at a rate of up to 15kHz. With the software package LASCON® Process Manager you can visualize, parameterize and monitor your laser process. With a simple script language you can program and execute up to 256 different laser scripts. With these scripts you can monitor your laser processes 100% and have a traceability of your entire production.

High speed fiber coupled pyrometer

With over 1500 industrial LASCON installations worldwide, Mergenthaler is the world market leader in temperature-controlled laser material processing.

Application for the Mergenthaler LASCON infrared pyrometers are:

Laser plastic welding: In laser plastic welding, LASCON regulates the welding temperature of the seam and ensures a perfect connection, which also offers the best optical results. The system provides 100% monitoring of production as well as storage of all essential process parameters. Also for precess control together with galvo scanners .

Laser soldering: The temperature monitoring of the laser soldering process allows a high-quality solder joint without burn and cracking.
