HeNe Lasers
Excelitas' line of REO HeNe Lasers is the leading high-performance HeNe instrument choice due to our precision optical fabrication and IBS coating capabilities. We are the only manufacturer to fabricate our own laser mirrors and integrate them into the HeNe Laser assembly. In fact, we were the first HeNe laser manufacturer to successfully design and manufacture mirrors for volume green HeNe lasers with their notoriously low gain. We have utilized our optical experience to develop a unique, fully-stabilized laser product that provides an ideal solution for laser-based instrumentation and metrology applications that require long-coherence length and high amplitude stability.
Excelitas' HeNe Lasers are now available to purchase online at Digi-Key.com.
