The SWL-7500 OEM-Grade Laser Diode Module Controller is designed specifically for the Single Wavelength series. This controller offers a low-noise, low-profile solution. While extremely small, it still provides low-noise current to the diode and maintains the diode temperature at a precise value. Extremely easy to use the unit also features RS-232 communications and a GUI interface with downloadable VIs for easy remote control and integration into your system.
