Constant current and constant
power control modes
Designed to compliment ILX Lightwave’s line of precision
laser diode instrumentation, the LDX-3100 and LDT-5100 offer
precise low-noise, high-stability current and temperature control
of laser diodes to meet the needs of critical OEM and other space
constrained applications.
The LDX-3100 laser diode current source provides the
exibility of a mountable circuit board with laboratory-grade
performance and proven laser protection. It can be operated
in constant current or constant power modes. Similarly, the
LDT-5100 thermoelectric temperature controller provides
outstanding temperature stabilization of laser diodes or
photodetectors.
The products can be used together or independently and are
easily incorporated into other products with demanding laser
diode drive requirements. Both are based on ILX Lightwave’s
proven circuit topologies, and are pin-compatible with ILX
Lightwave laboratory instruments and laser mounts.
