The Thorlabs LDC8010 is a modular laser diode current control module engineered for precision current regulation in demanding laboratory and professional environments. This single-slot PRO8 series module delivers ±1 A maximum output with 16-bit resolution (one part in 65,000) and operates in both constant current and constant power modes via back facet monitor diode or external analog input. The LDC8010 combines extremely low noise and drift performance with comprehensive laser diode protection to ensure stable, transient-free operation even during AC power interruptions.
