Microprocessor-controlled HeNe Power Supplies

PTI launches first microprocessor controlled line of Helium-Neon Gas Laser Power Supplies

PTI is pleased to launch eight new models of our next generation microprocessor-controlled HeNe power supplies. Those models include the SL23201, SL23210, SL23211, SL28201, SL28210, SL28211, SL23220, and SL28220.

Since 1969, Power Technology, Inc has manufactured and supplied the largest companies in the world with precision-controlled HeNe power supplies. Designed with universal compatibility in mind from all brands of Helium-Neon (HeNe) lasers.

Our power supplies work seamlessly with Lumentum, LASOS Lasertechnik, REO, Excelitas, Plasma JSC, CDHC Optics, Edmund Optics, ThorLabs, JDSU, Uniphase, Zygo, Agilent, Keysight, HP, Melles Griot, and other HeNe lasers. Our power supplies often surpass original equipment manufacturer (OEM) units in performance and are built with high-quality components for stability and longevity.

The models are designed to operate from 12 or 24 volt DC and are more cost-effective than previously available models. It is important to note that these new power supplies are a “direct replacement” for earlier models. 

We offer a wide variety of precision control electronics for Helium Neon Laser tubes. They feature fully encased electronics, dual input voltage, and generate a relatively small amount of heat. AC and DC input voltages are supported.
Use our selection tool below to find a new power supply compatible with your laser tube.
