General information on infrared light

  • Red-light lamps, infrared emitters and therapy devices emit in different wavelength ranges and at different power levels depending on the model.
  • Whether safety glasses are suitable therefore depends on the device used and its radiation spectrum – not just on the label «red light» or «infrared».
  • The Zhi IR 1.7 is not automatically suitable for every red-light lamp, infrared cabin or sauna, and it is not a safety glass for IPL or laser devices. Always follow the device manufacturer's instructions.

Does the Zhi suit my application?

Two steps: choose your device type, then enter the wavelength.

1. What type of device do you use?

Check device requirements

  • Which wavelengths or spectrum does the device manual specify?
  • Which eye protection or protection level does the manufacturer require?
  • Which distances and operating times must be observed?

Compare your device’s requirements with the documented Zhi specifications. If information is missing or the comparison is unclear, ask the device manufacturer to confirm the requirements.
