LDC-3916 In Stock

The Newport LDC-3916 is a Modular Laser Diode Controller designed to deliver precise temperature control and laser diode current regulation in a space-saving, rack-mountable package. With the capacity to manage up to 16 laser diodes within a single mainframe, this controller showcases exceptional capabilities enabled by ILX Lightwave for optical amplifiers testing and multiple pump control. The LDC-3916 is particularly well-suited for low-channel count burn-in systems, owing to its exceptional stability, minimal noise, and accurate current and temperature control functionalities. Furthermore, its remote operation capability through either an RS-232 serial interface or an IEEE-488 GPIB port enables independent control of all 16 channels.

The LDC-3916 boasts a bright vacuum fluorescent front panel display, presenting status screens with four channels visible at a time, allowing for easy scrolling to access any desired channel. In the status menu, various functions are available, such as enabling or disabling outputs, adjusting setpoints, and monitoring operations. Moreover, users have the flexibility to display any two parameters for each channel on the status screen, with an intuitive interface supported by screen-specific soft keys that streamline channel operation. The controller also offers an "All Channel" menu for initial setup and ten storage bins to save and recall instrument settings efficiently. The presence of a rotary adjustment knob, up/down arrow keys, and a numeric keypad further enhances the user experience for entering setpoints and other values. The LDC-3916, when connected to compatible GPIB technology, facilitates automated production testing by providing essential processing capabilities.

The adaptability of the LDC-3916 extends to a wide range of applications, including low channel count burn-in applications and multiple pump laser control for amplifier test applications. Notably, this controller demonstrates outstanding temperature stability, achieving an impressive +0.007 degrees Celsius level. The temperature control circuits optimize temperature settling times through a smart integrator control loop featuring expanded gain setting ranges. The current source topology employs an innovative, proprietary control loop incorporating state-of-the-art signal filtering and circuit board shielding techniques. Additionally, the controller features an adjustable voltage limit and faster shutoff to mitigate dangerous reconnect transients that may arise from intermittent connections between the controller and the laser diode. The LDC-3916 further offers the flexibility of operating in either constant current mode or constant optical power mode, accommodating different operational requirements as needed.
