UVC rays are useful thanks to their bactericide and ozonizing capacity, so they are used in the field of sterilization; another field of application that is being developed is in the polymerization of adhesives or resins (photoresi- st); as a drawback they cause more serious cases of erythema and conjunctivitis than UVB rays.
Depending on the effects that they produce, ultraviolet rays may also be classified as follows:
Producing ozone in the field | 180÷220 nm |
Producing bactericide (germicide) action in the field | 220÷300 nm |
Producing erythematous action in the field | 280÷320 nm |
Black light in the field | 320÷400 nm |
HD 9021 UVA
Radiometric probe for measuring radiation power, IRRADIANCE, in the UVA wave length 315÷400 nm, peak at 365 nm. Quartz diffuser for cosine correction. Measuring range from 10 nanowatt/cm2 to 200 milliwatt/cm2.
The typical response curve of the probe is as follows:
