Pair the WLD3343 Laser Diode Driver with either a WTC3243 or WTCP-5A5V Temperature Controller when precision laser diode current and temperature control are required. The WLD3343’s and the WTC3243’s are Li+ battery-compatible. These drivers are widely used in electro-optic qualification, Raman spectroscopy, medical diagnostic equipment, range finders, eye-safe atmospheric lidar and on research benches. System safety is paramount with Wavelength drivers.
