World’s Most Compact 4-Wavelength Laser Combiner for Flow-Cytometry and Particle Analysis

27 March 2018

VILNIUS, Lithuania, Feb. 21, 2018 - Integrated Optics, UAB has presented its newest upgrades to the World's smallest 4-wavelength laser combiner during the Photonics West 2018. The MatchBox combiner has got much more functional - the previously used multiplexer was replaced with 4 independent precision laser diode drivers, so from now on all 4 laser diodes can be modulated through dedicated TTL modulation pins irrespective from one another. That was an essential requirement from the flow-cytometry and particle analysis industries.

Furthermore, four slots of the upgraded combiner unit can be fitted with a mixture of detectors and emitters, making a very versatile and widely configurable optical engine for various fluorescence-based applications. Integrated Optics is working with the first integrators in the fields of droplet-based microfluidics and dynamic light scattering. The engineers are working to tailor optical layouts to a required light intensity distribution, angular and transversal beam overlap. Integrated Optics' robotic micro-optics assembly technology comes in handy in ensuring superior unit-to-unit reproducibility and production scale-up.

Novel Product Concept

The MatchBox laser combiner includes 4 laser diode drivers and digital control electronics, which allows smart control and diagnostics of the complete module.

The laser unit is designed as an integration-ready electro-optics unit, which can be connected to a control mainboard and power supply of an instrument. This way the laser/detector unit provides unprecedented compactness and functionality. Thus, mass production of multi-wavelength instruments becomes much easier and faster.

For scientific installations and various experimental setups, the laser combiner is provided with a quick-start breakout box, which has conventional ports for control, power and safety arrangements.

Communication protocol

MatchBox series lasers (2nd edition) feature a Universal Asynchronous Receiver/Transmitter (UART) controller interface. The pinout of MatchBox Combiner is an expanded version of standard MB2 pin-out. A 'breakout box' is used for converting UART into USB or RS232 protocols.

Fiber coupling and beam shaping options

The MatchBox laser combiner has multiple output options, like free-space, SMA port or multimode fiber. Custom beam shaping like line generator or flat-top is also available on request. Integrated Optics is working to release SM and PM fiber options in the nearest future.
