This review outlines the use, dosage, safety, and efficacy of narrowband UVB (NB-UVB) and targeted phototherapy. We are proud to have gained global recognition for delivering the highest quality product directly to end users and working in partnership with leading UV. The system mounts to an easily customizable 350 x 400 mm flange for convenient connection to a HV or gas flow system. Based on physical principles and supported by our earlier and Phase I Studies, far-UVC light (~222 nm) from a KrCl excimer lamp has all the anti-microbial advantages of conventional germicidal UV lamps, but without the corresponding human safety hazards. Excimer lamps are interesting for the generation of monochromatic radiation in industrial processes as they are cheap, robust, and can operate with eﬃciencies higher than 60%. Typical applications are low- and mid-pressure lamps which are used in disinfection, UV curing, surface activation and chemical activation of process gas. Key to this new offering from Bona is the ability to provide a wide range of variations of gloss (between <5 and 50). Decomposition of NO2 (200 ppm) in N2 or air by 172-nm Xe2 excimer lamp was studied at 1 atm. The innovative laser system delivers an unsurpassed repetition rate of 1050 Hz – currently the highest of all excimer lasers on the market. Recently, it has been shown that the efficiency of excimer lamps can be drastically increased in a pulsed regime. Suitable for laboratory & close in applications the 20 watt UVK-20w is an excimer lamp with a separate filter suitable for handheld & close up applications such as tissue disinfection or equipment sanitation. The mechanistic background is that far UVC light in the wavelength range of around 200 to 220 nm is strongly absorbed by essentially all proteins, and so its ability to penetrate biological material is very limited. PUV system provides pulsed high-energy blackbody in broadband width. Excimer lamps are used in various industries where short-wavelength ultraviolet light is required. EXCIMER LASERS 6901 TPC # 300 ORLANDO FL. Xe gas was used and its pressure is 300Torr. Since 1983, LightSources and its affiliated companies continue to be world leading light bulb manufacturers for specialty and custom lamps. Excimer UV lamps produce no infrared radiation, eliminating heat production and making them ideal for applications in specific industrial processes and in chemistry, biology and medicine. Creation of monochromatic and short wave UV irradiance with high energy (7,3 eV @ 172nm with Xe gas). This can be confusing because the wattage rating for lamps is the input power. The EX-400 ensures highly accurate, high quality modification, cleaning, and bonding compared to corona discharge method, plasma method, and even other excimer lamps. 100 watt lamp for an intensity of 21,700 µW/cm² @ 5cm or 8,900 µW/cm² @ 25cm distance. The Ushio modules are based on excimer laser technology and are often referred to as excimer lamps. The emission characteristics are reported for a small short-wavelength (UV) lamp filled with a krypton-bromine mixture and pumped by longitudinal glow discharge at a 100-mm distance between electrodes in a quartz tube with an internal diameter of 14 mm. Such sources deliver high-intensity radiation, needed, for example, for stimulating photo-. a DBD Xe excimer lamp can be dramatically increased to > 60% by employing pulsed (∼750ns FWHM) voltage excitation with ‘idle’ periods (∼40 µ s) between the pulses 1. To further improve the light efficiency and to reduce the overall dimension of lamps, the lamp lens at the micrometer scale is fabricated by excimer laser cross scanning on a polycarbonate sheet.

Excitation may be by E-beam or electric discharge.
