UV-C lamps of the type TUV have their main radiation at 253.7 nm. By using special glass generally no ozone generating radiation is produced. TUV lamps have a special Long Life inner coating. Therefore you reach a high useful lifetime with low depreciation of radiation.
Applications
deactivation of microorganisms (disinfection)
various photochemical and photobiological processes
irradiation of certain, in this area sensitive photopolymers
