SPL TECHNOLOGYTM
SPL or Square Pulse Light Technology represents a breakthrough in the Pulsed Light field. It differs from conventional Pulsed Lights at several levels.
Conventional Pulsed Lights Most Pulsed Lights deliver energy at a peak followed by a sharp drop during a shot which may either be one-off or sequenced (several sub-flashes at each flash). Energy is not therefore consistent throughout the duration of the pulse. Such inconsistency must be compensated for with higher-intensity energy use, with consequent increased risk to skin.
SPL Technology Using SPL technology, Yperion systems deliver a single square-shaped pulse which gives consistent energy throughout the firing. The target is therefore heated in a more consistent way, thereby enhancing light ray efficacy. Required energy is reduced and safety significantly increased.
In SPL Tecnology, pulses have enhanced efficacy over conventional forms. |

SELEKTIVNA FOTOTERMOLIZA
Définition When the light ray reaches the skin, a part of it penetrates the surface layers. It may then be absorbed by skin chromophores. When absorbed, it is transformed into heat. Selective photothermolysis is the specific action of heat resulting from light aimed at a specific target.
Targets The main skin chromophores are melanin, haemoglobin and water. Each chromophore has a different absorption capacity depending on wavelengths used. Perfect wavelength selection is essential for selectively reaching a precise target.
Parameters In addition to selecting wavelengths, exposure time and fluence (energy per cm˛) are two important parameters which it is essential to be able to vary independently if satisfactory results are to be obtained.

Pulsirajuća svetlost

PULSIRAJUĆA SVJETLOST Definicija Svjetlost je elektromagnesti val. Duljina svjetlosnog vala se mjeri u nanometrima (nm). Svaka boja svjetlosti ima specifičnu valnu duljinu (ljubičasta 400nm, crvena 800nm). Ultra ljubičaste (UV) zrake imaju duljinu kraću od 400nm , a infra crvene(IR) preko 800nm.
Kada se svjetlost emitira vrlo visokim intenzitetom u vrlo kratkim impulsima, tada govorimo o pulsirajućoj svjetlosti. Trajanje impulsa je nekoliko milisekundi (ms)
Svjetlost sadrži određenu količinu energije u česticama koji se nazivaju Fotoni. Ta energija se mjeri u Jul-ima(J). Tehnologija Pulsirajuća svjetlost se proizvodi u određenom rasponu valnih duljina (ood 300 do 1200nm). Nakon toga se filtrira kako bi se reducirao spektar i prilagodila potrebama tretmana. Za svjetlosnu zraku kažemo da je polikromatska (sastoji se od nekoliko boja)-
S druge strane, zraka koju emitira LASER, ima samo jednu valnu duljinu. Za nju kažemo da je monokromatska(samo jedna boja). Osim toga, laserska zraka je koherentna I fokusirana, t.j. svi valovi su u fazi I koncentrirani u jednu točku.
 
Klinička primjena S kliničke točke gledišta, LASER je pogodan samo za jednu primjenu u određenom vremenu, dok pulsirajuća svjetlos (IPL) s druge strane ima širok spektar i ta tehnologija ima višestruku primjenu na nekoliko tipova kože.
Pulsirajuća svjetlost je jednostavnija za upotrebu nego LASER, i daje identične, a često i bolje rezultate.
