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.

Why should you choose Excelitas as your provider of HeNe lasers?
Excelitas Technologies is a global leader in the design, engineering, and manufacturing of photonic solutions. Our bespoke, innovative products are designed to meet the demands of even the toughest applications. In 2018, Excelitas acquired Research Electro-Optics (REO), which has a legacy of producing proprietary mirrors for Helium-Neon or HeNe lasers in-house. For instance, REO was the first to successfully develop mirrors for green volume HeNe lasers, known for their low gain. This union offers the best of both worlds. It brings together the proven track record of the former and the high-quality HeNe laser manufacturing capability of the latter.
What kind of HeNe lasers do you offer?
Our REO HeNe lineup comprises multiple lasers with excellent features, including:
  • A unique metal body, allowing for superior beam point stability and suitability for original equipment manufacturer (OEM) applications
  • The highest power stabilized HeNe lasers at 1.5 mW
  • The line-tunable HeNe laser generating 500:1 linearly polarized outputs of five independent line-selectable wavelengths: 543 nm, 594 nm, 604 nm, 612 nm, and 633 nm
  • The long coherence length of HeNe laser solutions ideal for metrology applications
What is a HeNe HeNe Laser used for?
The REO HeNe lasers are ideal for laser-based instrumentation and metrology applications requiring long HeNe coherence length and high amplitude stability. In particular, here are some of the applications with specifications matched by our HeNe lasers’ capabilities:
  • FTIR applications – Narrow/stable linewidth
  • Semiconductor Inspection
  • Particle Counting
  • Metrology
  • Alignment
  • Raman Spectroscopy
  • Research Labs & Universities
  • Confocal Microscopy
  • Food/Agricultural sorting
  • DNA Sequencing
  • Flow Cytometry
  • Imaging and Medical Equipment
  • Opacity Monitoring
  • Maritime Visual Guidance Systems • Hematology
  • Polarization Experiments
  • Ellipsometry
What is the quality assurance process for your HeNe lasers?
We coat our self-manufactured HeNe mirrors, enabling us to customize coating specifications. In the customization process, we use in-house laboratory developed tests (LDTs), low absorption coatings, and superpolished surfaces. Of course, this approach is taken in our state-of-the-art ISO 9001 facility. Our manufacturing procedures are compliant with quality management and environmental standards. Our products undergo rigorous testing to ensure they meet the requirements of high-demand applications, such as long HeNe coherence length.
Do you offer custom HeNe lasers?
Yes, we do. Do know that our HeNe lasers have a unique metal body that can be easily attached to optical assemblies, such as telescopes, periscopes, and fiber-coupling, to the body of our laser, rather than just the housing. But should you need an application-specific design, our team is more than willing to assist you. Contact us to learn more about our customization process.
