Universal Laser Diode Controller 500 (ULDC-500)

Data Sheet

Product Overview

The Optilab ULDC-500 is a fully integrated Universal Laser Diode Controller designed for 14 pin butterfly package. This compact, easy to use laser diode driver module operates under a single + 5 V power supply. ULDC-500 offers LD current and temperature control that comes with a built in LCD display and a USB port for external PC control. The module is equipped with an adapter board, thus making it compatible with 14 pin butterfly LD module for any laser manufacturers by switching the daughter boards provided in the package. It provides a LD current range of 0 – 500 mA with a setting resolution of 1 mA and Temperature range of 10 to 40 C with a setting resolution of 0.1 °C.
