Intense pulsed light OPT (IPL), technology uses a high-powered, hand-held, computer-controlled flashgun to deliver an intense, visible, broad-spectrum pulse of light, in about the visible spectral range of 400 to 1200 nm.

Various cut-off filters are commonly used to selectively filter out lower wavelengths, especially potentially damaging ultra violet light. The resulting light has a spectral range that targets specific structures and chromophores (e.g. melanin in hair, or oxyhemoglobin in blood vessels) that are heated to destruction point and reabsorbed by the body.

OPT IPL shares some similarities with laser treatments, in that they both use light to heat and destroy their targets. But unlike lasers that use a single wavelength (color) of light which typically matches only one chromophore, and hence only one condition, IPL uses a broad spectrum and when used with filters, allows it to be used against several conditions. This can be achieved when the IPL technician selects the appropriate filter that matches a specific chromophore.

OPT Intense pulsed light is the use of intense pulses of non-coherent light over a range of wavelengths from 490 nm to 1200 nm. Flash-lamps produce high output bursts of broad spectrum. Photo Biotech Radiant IV built in cooling technology is used to protect the skin that is in contact with the device.
