Excimer lamp  

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...

  FEATURES & BENEFITS Mercury Free - Environmental Friendly Effective Germicidal Wavelength (Peak at 222nm) More Effective Reduction of Viruses, Bacteria, and Spores than 254nm  Wide Operating Temperature (Not affected by ambient temperature) Instant On/Off at Full Output Power Various Product Lineup APPLICATION Air / Surface / Water Disinfection Safe 222 TM, UNILAM EXCIMER LAMP SERIES  It is well-known that the radiant power of general mercury lamps (Low pressure mercury lamp) is very sensitive to ambient thermal changes.  Fig.2 shows the temperature stability of a Unilam Safe 222 TM excimer lamp compared to that of a low pressure mercury Lamp (LP lamp) Unilam Safe 222 TM Excimer lamp needs no warm-up time and radiant power was maintained within a range of 96% to 100%, while conventional germicidal UVC lamp needs enough time to reach maximum irradiance. advertisement : excimer lamp is UNILAM E-mail : ruthkim@unilam.co.kr
