-
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.
-
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 and pain management.
-
Laboratory Diagnostics: Used in laser-based blood analyzers and confocal microscopy.
-
Ophthalmology: Providing the base light source for retinal scanning and diagnostic mapping.
Q1: Why choose a He-Ne laser tube over a red diode for medical alignment?
A: 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.
Q2: How does the length (150mm vs 1000mm) affect the treatment?
A: 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.
Q3: Is the output power consistent across the entire lifespan?
A: 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.
Q4: Do these tubes require specific power supplies?
A: 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.
