New product, complete redesign and improvement, leveraging new technological advances and several years of experience with the previous LDD generation. A new, much faster processing core enables better timing, faster pulses, faster rise/fall times, while still using the proven and stable ME-COM interface protocol.
If you are interested in the LDD-1137, or even wish to test a prototype, please do not hesitate to contact us.
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.
