ENGLISH

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:
