    Laser Diode APC Driver ASIC:

    The EDL-1 device is a driver for laser diodes in continuous wave operation which requires only few external components. The broad power supply range of 2.5V to 6V and the integrated protection allow for battery operation with a minimum of two cells. The driver includes integrated circuitry protecting against destruction by ESD, excessive temperature and over current. The driver also filters the laser diode power supply for transients. The power supply is regulated and adapted for the laser diode used by an external resistor at PD. The monitor current acts as a reference and is regulated independent of the influence of temperature and supply voltage (range: 10ľA to 0.5mA). There is only one external capacitor required. In the event of failure, such as over current in the laser path with a lack of feedback, for example, a quick power lockout is activated. The shutdown continues until power is reapplied, permitting a restart. The strain on power packs and batteries is relieved and the laser class is retained even in the event of a disturbance.

    FEATURES
    • CW operation up to 60mA from 2.5..6V supply voltage
    • Simple power adjustment via the external resistor
    • Control loop accuracy better than 5% with changes in temperature, supply voltage and load current
    • Permanent shutdown with excessive temperature and overcurrent (i.e. if the laser diode is damaged or the feedback current path fails)
    • Wide monitor current range from 10µA to 0.5mA
    • One external capacitor is required on output

    MEMS : Laser Scanning Mirror

    LB02500 is a single axis micro scanning mirror designed for laser scanning application. It's designed by the MEMS (Micro-Electro-Mechanical System) technology. LB02500 consists of a scanning mirror and the driving circuit for the scanning mirror driving. Despite a small active area, LB02500 provides a large scan angle and low scan jitter. LB02500 can be used as a laser line scanning like laser barcode scanning, laser printer scanning etc... It delivers a low jitter, high accucy, low power comsumption, small dimention and easyly control scanning solution.

    FEATURES
    • Single axis MEMS micro scanning mirror
    • 4x1 mm elliptical mirror coated for high reflectivity
    • Large scan angle: +/-40 degree
    • Low power consumption
    • Resonant operation for low scan jitter
    • Compact and lightweight by single-crystal silicon structure
    APPLICATIONS
    • Laser priting, laser barcode
    • Laser scanning and sensing
    • No contact measurement and sensing
