Laser Current & TEC Control Modules   

OptoSci LDR   

The OptoSci LDR range of laser driver modules provide a versatile and user friendly platform for stable current and thermo-electric control (TEC) of laser diodes, SOAs, SLDs, 980 nm pump lasers and so on. The fully integrated digital Eurocard modules are designed for device characterisation, prototype development and experimental systems and offer easy device integration, full PC control and monitoring, or set & forget operation utilising the on-board EPROM.
 
A typical LDR module includes power supply, ZIF mount and heatsink for 14-pin butterfly package, USB interface and PC communications cable, and full V-DRIVE control software for easy operation straight out of the box.

OptoSci's LDRS is a Small Form Factor OEM device driver with a stable, low noise 250 mA or 1.0 A current driver and TEC supplied in a credit card size, three board stack. It uses the same LDR core driver hardware and offers similar high specifications as the Eurocard evaluation modules (LDR250E and LDR1000E). LDRS is designed so that it can normally be readily integrated with your active devices (SLED, SOA, 980 nm Pump Lasers, DFB Laser Diodes, etc.) and a custom enclosure to enable you to provide value-added products to your customers rather than just supplying active devices.
 
The LDRS OEM board is supplied with the following items as standard: V-DRIVE OEM Software for setting device operating parameters, USB interface, Solder Mount for 14-pin butterfly packaged fibre coupled laser, SOA or similar device and an operators manual.
