LDTC modules are in use around the world providing
trouble‑free reliability in range finders, telecom laser
modules, military-aerospace research and development,
airborne metrology, academic research, laser diode LIV
testers, and more.
POWER YOUR APPLICATION WITH
THE RIGHT FEATURES
The popular FL500 is known for trouble-free operation.
The current limit circuit cleanly clamps laser diode current
without ringing or overshoot, and recovers without inducing
a phase shift in a modulated laser signal.
The WTC32ND ultra-stable temperature control module
is known for precision and reliability. Independent coolingand
heating-current limits allow the LDTC to be used with
thermoelectric coolers or resistive heaters, and either
negative or positive temperature coefficient sensors.
