UVN is the exclusive name of our standard low pressure lamps. On request we are able to deliver such lamps in different diameters and lamp currents. UVN lamps emit radiation mainly at the wavelengths 254 nm and 185 nm. Using different quartz glass types we are able to block or pass the 185 nm optionally. On request we are also able to deliver lamps partially equipped with 185 nm quartz for optimizing ozone generation.
