    Digital L-Type

    DATASHEET

    The L-Type integrates the single-mode U-Type module into a UL/CE and IEC-certified turn-key system. This includes a standard laser driver, TEC control electronics, and power supply. Comes standard with a laser enable switch, safety key lockout, remote interlock, and emergency shut-off button (EMO). USB connection and LabView customer GUI allow the user to control the device remotely.
