Product Details

Detailed Description

The LDD-1137 is a specialized laser diode driver, able to precision-drive laser diodes in continuous and pulsed operation. New emerging technologies like eGaN FETs enable faster pulses, improved wave forms and better efficiency. A new processing core enables a faster processor connection to the powerful FPGA, more interfaces, more precise timing, additional functions and much more, while still maintaining a 1.5 mA resolution with much higher current and keeping a very low output ripple.

Equipped with optional light measurement circuitry, the LDD-1137-LPC can also be operated as a Laser Power Controller (LPC).

All LDD-1137s offer various safety features, including an input for laser diode temperature monitoring. They are fully digitally controlled; their firmware is upgradeable to offer various communication options and to meet specific customer requirements.
An ISO 13849-1 Performance Level E certified version will be available sometime after the standard version.
