SPOLD LD Irradiation Light Source

L13920-411M

The SPOLD built-in process monitor constantly captures thermal information on the laser irradiation point to allow quality control during laser processing, making it ideal for use in mass-production processes such as for plastic welding and soldering.

Features

  • Transmitted laser light and thermal information with a single fiber simultaneously
  • Thermal information of laser irradiation point can be acquired without any adjustment
  • Compatible with galvano mirror system
  • High speed 1 millisecond sampling to detect an instantaneous change
  • Simplified processing peripheral parts by compact irradiation unit

Applications

  • Plastic welding
  • Adhesive thermal curing
  • Soldering
  • Other process or principle using laser as heat source
