Oeabt offers laser diodes in two packages—TO-18 and TO-5—with different output characteristics (power, wavelength, beam size, shape, etc.), for use with the LD light source controller.The diode mount is mainly used to install TO-18 and TO-5 laser diodes, featuring SM05 (0.535″-40) or SM1 (1.035″-40) threads. It facilitates alignment between the laser diode and the optical axis of the lens sleeve, enabling assembly of SM-threaded components. The diode can be fixed with the supplied retaining ring.The LD light source controller is an LD driver with flexible operation, wide compatibility with laser diode specifications, and high control precision. It integrates driving and control functions, and its output interface is compatible with 2-pin and 3-pin LD laser diodes—different light sources can be switched simply by replacing the laser diode. It supports a wide input voltage range of 12–24 V DC, with a maximum output current of 3 A. It is ideal for high-precision, stable applications requiring multiple light sources.InterfaceSpecificationPin/DefinitionRemarks12V DC ConnectorDC 12V–24VDC 5.5-2.1—PWM Input ConnectorMax: 6V, Min: 2.8VFrequency: 0–5 kHzSMA ConnectorSMA center pin: PWM positive;outer thread: PWM negativeOutput ConnectorMax: refer to model;Min: 0 mAFrequency: 0–5 kHzPin 1: LD ; Pin 2: LD-;Pin 3: PD/NCXH2.54-3P connector;pin order left to rightMode SwitchContinuous Wave (CW) ModePulse Control (PULSE) Mode—Slide switch to labeled positionCurrent AdjustmentMax: refer to model;Min: 0 mA—Clockwise: increase output current;Counterclockwise: decrease output current;minimum output: 0Main Features of the Controller:Adjust the frequency and brightness of LD laser diodes via an external PWM signal; frequency range 0–5 kHz, duty cycle range 0–100%.Adjust light source brightness via external current adjustment.The housing uses a large-volume aluminum heat sink, ensuring stable and reliable output current even at full power.
