Abstract:

A detailed protocol is presented documenting how a `sensor factor' correction should be calculated when undertaking quasi collimated beam experiments using a polychromatic medium pressure ultraviolet lamp. The correction factor was determined as 0.778 through Pyrex filtration test. This new protocol is particularly important if the radiometer sensor has significant sensitivity at wavelengths longer than 300 nm.

Cet article présente un protocole détaillé documentant comment calculer la correction d'un « coefficient de capteur » lors d'expériences sur des faisceaux quasi collimatés utilisant une lampe ultraviolette polychromatique à pression moyenne. Le coefficient de correction a été déterminé à 0,778 par l'essai de filtration avec Pyrex. Ce nouveau protocole est particulièrement important si le capteur radiométrique est très sensible aux longueurs d'ondes supérieures à 300 nm.
