Principal configuration of UV-light measuring
Transmission measuring: • UV collimation device • optical fiber • wavelength selective receiver
Lateral UV-light launching: • no UV collimation device • special optical fiber • wavelength selective receiver
New: measuring the UV light by lateral launching it into optical fibers!
