Helium-Neon Laser Buying Guide

When selecting a helium-neon laser, consider the wavelength you require for your specific application, as different models may emit different colors such as red or green.

Check the output power and ensure it aligns with your required precision level. Stability and coherence are also crucial factors to evaluate.

  • Verify the condition of the tube and optical components to ensure no degradation has occurred.
  • Examine the power supply compatibility and any necessary accessories that might be required.
  • Consider if a stabilized or frequency-locked model is necessary for higher precision needs.
  • Request calibration records and maintenance logs to confirm operational reliability.
