Product Details

Detailed Description

The LDD-1121 is a specialized laser diode driver able to precision-drive laser diodes in continuous and pulsed operation. Core element of the LDD's internal current source is the generation of highly precise 333 ps timing steps that results in 1 mA resolution and very low ripple.

Equipped with optional light measurement circuitry, the LDD-1121-SV-LPC can also be operated as a Laser Power Controller (LPC).

All LDD-1121s 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.
