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.
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. The lower row of pins is the same as for single-wavelength lasers, while the second (upper) row is added for individual TTL modulation of each laser diode installed in the combiner.
A 'breakout box' is used for converting UART into USB or RS232 protocols. The converter chip for USB is 'Silicon Labs CP2102' and for the RS232 it is 'MAX232'. Aditionally, the breakout box of MatchBox combiner is equipped with necessary circuit for communication with QC2.0 and QC3.0 power supplies.
Pins for Tight Integration
10 pins at the back of the laser combiner provide full access to complete functionality of the combiner.
Pins are located at the back side of the enclosure and distributed in a way, which allows to implement a mechanical reverse lock.
Prerequisites for such integration are a microcontroller mainboard supporting UART communication, 9V (or QC2.0 or QC3.0 compliant) power supply and 4 TTL channels for individual on/off modulation (or fast PWM power control) of each laser diode.
- L0 on/off diode TTL, 5V tollerant
- L1 on/off diode TTL, 5V tollerant
- GND ground connected to the laser body
- L2 on/off diode TTL, 5V tollerant
- L3 on/off diode TTL, 5V tollerant
- GND ground connected to the laser body
- Prog. pin needs to be programmed to set 9V voltage, if a QC3 or QC2 compliant USB power supply is used. Another use of this pin is to control fan of a heatsink, based on laser body temperature.
- Rx UART communication, 5V tolerant
- Tx UART communication, 5V tolerant
- Vcc 9V or QC3.0 compliant power supply.**
** for communication with QC3.0 compliant power supply, the programmable pin needs to be configured for communication with the power supply.
Breakout Box Explained
The Breakout Box contains UART-USB converter circuit and conventional connection ports in a plastic housing.
- Data USB (left) is used for communication with a PC
- Interlock occupies two pins. When the pins are shortened with an interlock loop, the laser can be operated
- L0, L1, L2, L3 are all TTL modulation pins for corresponding LD channels or read-out pins for photodetectors, depending on product configuration.
- Power USB-C (right) connector is used for connection to a QC2.0 and QC3.0 compatible power supply.
- FAN ctrl. connector (not visible, on the right side of the breakout box) is compatible with all our fan cooled heat sinks.
Device information shows key information about a laser, which is connected. Firmware, serial number, product code, operational hours and turn-on counter. In the software, it is possible to set if the laser should auto-start once connected to a power supply.
A small footprint aluminum adapter to a standard M6 breadboard. It uses low profile M6 screws, thus the height profile is just 4 mm.
A water-cooled adapter to standard M6 breadboard. Used for achieving top stability and dissipating large amount of heat.
