An Introduction to the Ultra-Compact MatchBox Laser Combiners

The Wavelength Laser Combiners, part of the Matchbox series from Integrated Optics, feature the world’s smallest laser combiner footprint. Combiner Lasers include up to four wavelengths and are ideally suited for portable multiwavelength laser applications in diagnostics, sorting and illumination.

This post introduces the Matchbox Wavelength Combiners and describes their key features and applications.

Key Specifications 

  • Compact Laser Combiner
  • Four wavelength options
  • Plug-and-play solution
  • A single user interface for all four lasers
  • TEC cooling
  • Color mixing
  • USB power
  • High-end stability and flexibility
  • Fast warm-up time (bi-directional TEC)

Ultra-Compact All-in-One design

The MatchBox laser combiners include up to four individually controllable laser diodes or photo detectors, with free space or multi-mode fiber output. Wavelength Combiners offer alignment-free operation and can be operated very economically. Each individual wavelength is controlled through an easy-to-use PC interface allowing the user full control.

The Laser Combiners feature hands-free operation supported by fast-warm up time and multiplexing electronics. Each fiber-coupled unit within the series combines several wavelengths into a multi-mode output fiber. All optics and electronics are fitted into the ultra-compact Matchbox housing and are designed with built-in thermally stabilized optics.

The laser unit is designed as an integration-ready electro-optic unit, which can be connected to the control mainboard and power supply of an instrument. Multi-wavelength instruments incorporating Laser Combiners are easy to operate and deliver exceptional results.

The Laser Combiners have a standard matchbox footprint and are compatible with all MatchBox accessories.

Two standard wavelength combinations, commonly used in fluorescence applications, are available.

  • 405nm, 450nm, 520nm and 638nm
  • 405nm, 488nm, 520nm and 638nm

Software Interface

Matchbox Wavelength Combiner control software is used to monitor multiple parameters including maximum laser diode current, specific temperatures for TEC1 and TEC2, and load percentage of the Peltier element.

The software displays key information about the laser, once it is connected, such as the serial number, product code, firmware and operational hours. An additional feature available is an auto-start option, once the Wavelength Combiner is connected to a power supply, for flexibility and ease of use of the laser module.

Thermally Stabilized Optics

Matchbox Wavelength combiners integrated precision driver electronics provide low-noise and stable operation over a broad temperature range. The laser diode modules incorporate fast-warm up time (bi-directional TEC).


Portable Multi-wavelength Laser Applications

The powerful Laser Combiners, implemented in the MatchBox laser platform, are ideally suited for applications such as wide field illumination in fluorescence microscopy, flow cytometry, food sorting and inspection, medical applications, metrology, and quality control. Matchbox Laser Combiners offer an advanced and original design which is used within the microscopy and spectroscopy industry.

Key Applications

  • Wide-field and fluorescence microscopy
  • Flow cytometry
  • Food sorting and inspection
  • Medical applications
  • Metrology
