Laser Diode Driver and Temperature Controller

Wavelength Electronics (Bozeman, MT) introduces the LDTC 2/2 laser diode driver for integrated laser diode or LED modules that include temperature control, often utilized in medical diagnostic equipment, remote sensing, analytical instrumentation, military, and communication design. The unit combines the WLD3343 temperature controller and the WTC3243 laser diode driver in one compact package that supplies 2.2 amps of drive current to each component. Temperature is controlled by a PI loop with configurable heat and cool current limits. The LDTC 2/2 is compatible with A/B type lasers and allows photodiode power monitoring in constant current mode.
