Understanding the 950 nm Wavelength: All You Need to Know

Infrared light is a type of electromagnetic radiation with a shorter wavelength than visible light. It is characterized by its ability to penetrate materials, making it useful in various applications such as remote sensing, thermal imaging, and communication. One of the most commonly used infrared wavelengths in these applications is 950 nm. In this blog post, we’ll explore everything you need to know about the 950 nm wavelength, including what it is, how it works, and its various applications.

What is the 950 nm Wavelength?

Infrared light falls on the electromagnetic spectrum wavelengths between visible light and microwaves. It has a longer wavelength and lower frequency than visible light, which makes it invisible to the human eye. The wavelength of infrared light ranges from as short as 700 nm to as long as 1 millimeter.

The 950 nm wavelength is a specific range within the infrared wavelength spectrum. It falls towards the shorter end of the spectrum, making it closer to visible light in terms of wavelength. 950 nm is a near-infrared wavelength, which means it has the ability to penetrate deeper into tissues and materials than longer-wavelength infrared radiation.

Is 950 nm Visible?

No, 950 nm is not visible to the naked eye. Visible light ranges from around 400 to 700 nm, so 950 nm falls outside of this range. However, even though we can’t see 950 nm with our eyes, it still has many practical applications.

What has a Wavelength of 950 nm?

In addition to the various applications of infrared light mentioned earlier, several devices and technologies use the 950 nm wavelength specifically. These include:

  • Fiber optic networks: 950 nm is one of the wavelengths utilized in fiber optic communication systems.
  • Laser diodes and LEDs: Many laser diodes and LEDs emit light at the 950 nm wavelength.
  • Medical devices: Some medical devices use light therapy at the 950 nm wavelength, such as those used for pain relief or promoting wound healing.

What Wavelength for Wrinkles?

There is evidence to suggest that light therapy can help reduce the appearance of fine lines and wrinkles. The specific wavelength that is most effective for wrinkles varies depending on the study, but several studies have shown positive results using near-infrared wavelengths between 800 and 1000 nm. This includes the 950 nm wavelength, which has been shown to promote collagen production in the skin.

Electromagnetic Spectrum Wavelengths in nm

The electromagnetic spectrum is divided into several categories based on wavelength and frequency. Here are the approximate ranges of wavelengths in each category:

  • Gamma rays: less than 0.1 nm
  • X-rays: between 0.1 and 100 nm
  • Ultraviolet (UV) radiation: between 100 and 400 nm
  • Visible light: between 400 and 700 nm
  • Near-infrared (NIR) radiation: between 700 and 2500 nm
  • Mid-infrared (MIR) radiation: between 2500 and 25,000 nm
  • Far-infrared (FIR) radiation: between 25,000 and 350,000 nm
  • Radio waves: greater than 350,000 nm

Visible Light Wavelength

Visible light is the part of the electromagnetic spectrum that we can see with our eyes. It ranges in wavelength from around 400 to 700 nm, with shorter wavelengths appearing blue or violet and longer wavelengths appearing red or orange.

Infrared Wavelength Range in nm

As we mentioned earlier, the range of infrared wavelengths extends from around 700 nm to 1 millimeter. Within this broad range, different types of infrared radiation are classified by their specific wavelengths. Here are some of the common classifications:

  • Near-infrared: between 700 and 2500 nm
  • Mid-infrared: between 2500 and 25,000 nm
  • Far-infrared: between 25,000 and 350,000 nm

X Ray Wavelength Range in nm

X-rays have a very short wavelength, ranging from around 0.1 to 100 nm. This makes them useful in medical imaging and other applications where high-energy radiation is needed.

Is Infrared Light Given Off by Stars?

Yes, infrared radiation is emitted by many objects in the universe, including stars. In fact, some types of stars emit more infrared radiation than visible light, such as red giant stars and brown dwarfs.

How Many nm is Good for Red Light Therapy?

Red light therapy is a type of light therapy that uses red or near-infrared light to promote healing and reduce inflammation. The specific wavelength used in red light therapy varies depending on the device and the application, but many studies have shown positive results using wavelengths between 600 and 1000 nm. The 950 nm wavelength is considered particularly effective for promoting collagen production in the skin.


In summary, the 950 nm wavelength is a specific range within the near-infrared spectrum that has a range of practical applications. It is used in fiber optic communication systems, laser diodes, and medical devices, among other things. Additionally, the 950 nm wavelength can be used in light therapy to promote collagen production and reduce the appearance of wrinkles. Although it is not visible to the naked eye, the 950 nm wavelength plays an important role in many aspects of our lives.
