Xenon flash/laser lamp

Image
  Advantage No chemicals, Mercury free - Eco friendly Fast replication rates - time reduction Instant on/off Low substrate heating UV to IR spectrum -strong energy short time surface strike electric arc lamp designed to produce extremely intense, incoherent, full-spectrum white light for a very short time Xenon flash tubes have been used to produce an intense flash of white light, some of which is absorbed by Nd:glass that produces the laser power for inertial confinement fusion. In total about 1 to 1.5% of the electrical power fed into the flash tubes is turned into useful laser light for this application. Pulsed light (PL) is a technique to decontaminate surfaces by killing microorganisms using pulses of an intense broad spectrum, rich in UV-C light. UV-C is the portion of the electromagnetic spectrum corresponding to the band between 200 and 280 nm. Pulsed light works with xenon lamps that can produce flashes several times per second. Disinfection robots use pulsed UV light. A r...

Do you know far uv?

Far uv (200-225nm) Far UV-C is high-energy radiation which can directly damage DNA and key organic molecules such as proteins.  The biophysical basis for the claims that Far UV-C is ‘skin and eye safe’ is that the damaging radiation is entirely absorbed within the outer, dead, layers of skin and eye and does not reach the inner, live cells; if the radiation were to hit these cells (which happens at longer wavelengths like 254 nm or longer), they would be damaged as a result.  An increasing number of studies have been published discussing acute and chronic exposure to Far UV-C, most commonly using optically-filtered Kr-Cl excimer lamps. These studies have investigated the effects of Far UV-C radiation on mice and human tissues by measuring key chemical and physical changes known to indicate damage from UV-C exposure.  It was found that these same damage indicators were not observed under Far UV-C irradiation.  (Yamano et al., 2022, Yamano et al. , 2022; Buonanno et al...

Vitiligo one of the treatments

Unilam's excimer lamp can be used in vitiligo treatment light source What is Vitiligo? Vitiligo is white spots of various sizes and shapes all over the skin. It is a typical depigmented skin disease. Vitiligo is caused by loss of melanocytes in the skin. In patients with vitiligo, this melanocyte is partially lost for various reasons,  resulting in white spots on the skin. Treatment of vitiligo is not easy. However, with early and appropriate treatment, It can prevent progression and improve significantly. one of the treatments Excimer - It uses a 308nm wavelength laser beam to  stimulate the migration and proliferation of lost melanocytes. It has the advantage of being able to irradiate strong energy  intensively only on the lesion and that it can be treated even in areas  that are difficult to reach with UV treatment. data source : https://www.cmcvincent.or.kr/page/department/B/1168/1 photo source : https://en.wikipedia.org/wiki/Vitiligo 백반증 손
