Hair removal…skin rejuvenation…treatment of certain skin conditions…These are all applications in which IPL is commonly used. IPL, or Intense Pulsed Light, is a technology which uses high intensity light pulses to perform various medical and esthetic skin treatments. The light source is typically a flash lamp such as Xenon, and various manufacturers have their own unique protocols of spectral filtering, pulse timing, and beam delivery systems, all optimized for specific types of treatment. IPL sources are not quite lasers, but with many tens of J/cm2 zapping human skin, they can still do serious harm if the system is behaving even a little bit differently than it’s meant to. Even in non-medical, unregulated cosmetic applications, there is a real need to regularly monitor the IPL’s performance. Thermal laser sensors are a standard solution for measuring the energy of a so-called single-shot pulse of light. When it comes to measuring the energy of an IPL pulse, though, there are some unique challenges:

  • Broad angular distribution – which makes it difficult to capture the full beam
  • Broad spectral distribution – which makes it difficult to maintain accurate calibration
  • High energy and energy density – so the sensor’s absorber had better be able to take it, without damage
  • Many (if not most) IPL applications involve the use of optical coupling gel on the patient's skin to reduce reflective losses as the light goes from one optical medium (air) to another (skin), by reducing the step size of the refractive index. For the measurement to have maximum clinical meaning, it should be performed under similar optical conditions to those of the IPL's clinical use. That means using gel (or water) on the sensor – without destroying it.
Ophir offers a number of sensors specifically designed for IPL applications, so they enable you to meet these challenges.

The Importance of Verifying the Output of Your Aesthetic Light Treatment Sources

Intense Pulsed Light (IPL) is a commonly used tool for a variety of esthetic, as well as medical, skin treatments. IPL devices are non-laser high intensity light sources that make use of a high-output flashlamp to produce a broad wavelength output of noncoherent light, usually in the 500 to 1200nm range.

Intense Pulsed Light sources (IPL) are used extensively in skin treatment. For safety, skin care professionals often need to regularly measure and calibrate their IPL machines. Read more >

5 Situations Where Laser Performance Measurement is Necessary

Measuring the performance of a laser has possible for a number of years and is accomplished with a variety of techniques. These electronic laser measurement solutions give the laser user more relevant, time-based data that shows trends in laser performance rather than single data points. While these solutions have provided laser users with the ability to present data in a simple and easy to understand manner, the application of the data still seems to be unclear to many laser users.
