Description
150-1000mm HeNe Glass Laser Tube Medical Grade 35mW Output Power
Our Medical-Grade He-Ne (Helium-Neon) Glass Laser Tubes are the industry standard for applications requiring a highly coherent, monochromatic red light source. Ranging from 150mm to 1000mm, these tubes deliver a stable 632.8nm beam, essential for surgical laser alignment, blood irradiation therapy, and advanced medical imaging. Engineered with a hard-seal construction, our He-Ne tubes provide the unwavering beam pointing stability and low-noise performance that medical OEMs and practitioners demand.

Core Product Advantages
  • Exceptional Beam Pointing Stability: Our tubes are designed to minimize drift during warm-up, ensuring that in robotic surgery or radiation therapy, the aiming beam remains perfectly centered on the target throughout the entire procedure.
  • Low Optical Noise: Engineered with high-purity gas mixtures and precision-aligned mirrors, these tubes produce a "clean" beam with minimal power fluctuations (<1% RMS), which is critical for flow cytometry and blood analysis.
  • Hard-Seal Glass Technology: Unlike soft-seal tubes that degrade over time, our Hard-Seal construction uses glass-to-metal vacuum seals that prevent helium leakage, extending the shelf-life and operational life to over 20,000 hours.
  • Cold Cathode Design: The internal cold cathode ensures a low starting voltage and minimal heat generation, protecting the delicate internal components of high-end medical diagnostic machines.

Clinical Applications
Laser Aiming & Alignment: Serving as a high-visibility guide for CO2 or Nd:YAG surgical lasers.
Low-Level Laser Therapy (LLLT): Effective for non-invasive wound healing.
Laboratory Diagnostics: Used in laser-based blood analyzers and confocal microscopy.
Ophthalmology: Providing the base light source for retinal scanning and diagnostic mapping.

Product FAQ
Why choose a He-Ne laser tube over a red diode for medical alignment?
While diodes are smaller, He-Ne lasers offer superior beam quality TEM00 and significantly lower divergence. For long-distance alignment or precision surgery, the He-Ne beam remains a tight, perfect circle, whereas diode beams often become elliptical and blurred.
How does the length (150mm vs 1000mm) affect the treatment?
Shorter tubes (150mm-250mm) are ideal for compact aiming devices. Longer tubes (500mm-1000mm) produce higher power outputs (up to 35mW), which are required for therapeutic irradiation where depth of penetration is necessary.
Is the output power consistent across the entire lifespan?
Yes. Thanks to our internal catalyst and hard-seal mirrors, the power degradation curve is extremely flat. You can expect consistent clinical results from the first hour to the 20,000th hour.
Do these tubes require specific power supplies?
He-Ne tubes require a specialized high-voltage starter. We provide matched Medical-Grade Power Supplies to ensure the tube ignites instantly and operates with zero flicker.
