DiodeGuard® is VueMetrix's invention for protecting your investment of multiple laser diodes connected in series. DiodeGuard® prevents cascading failure by suppressing current spikes induced by accidental short circuit or intermittent connection.

VueMetrix® Inc. today announces the award of US patent 7663854 on DiodeGuard®. DiodeGuard® is available on the VUE MV21 and VUE MV40 high voltage high power laser diode controllers. DiodeGuard® is a cost effective and power efficient protection invention for powering 10 to 20 laser diodes connected in series. Joe Avery, Director of Sales, stated "connecting a large number of laser diodes in series minimizes the cost of powering each laser diode, however, an electrical short of a single diode would induce a destructive current spike which could destroy the entire string of laser diodes. DiodeGuard® is imperative in protecting the laser diodes while minimizing overall system cost."

VueMV21 and VueMV40 high voltage and high power laser diode controller Kits contain everything you need to get started:

  • Windows software, Enclosure with self contained AC/DC power supply and mating connectors
