Title
(EN) RADIATION DETECTOR
(FR) DETECTEUR DE RAYONNEMENT
Abstract
(EN)
An ultra violet radiation detector comprises a slice of silica (10) having an entrance slit (18) from which radiation diverges to a curved reflective face (20, 22) which reflects it to a planar diffraction grating (28) as a convergent beam. The grating focuses a required spectral order on an array of UV detectors (24). Usually the first order spectrum is focused. The detector may be hand held.
(FR)
Détecteur de rayonnements ultraviolets comprenant une tranche de dioxyde de silicium (10) comportant une fente (18) d'entrée à partir de laquelle le rayonnement diverge vers une face réfléchissante courbe (20, 22) qui le réfléchit sur un réseau (28) de diffraction plan sous forme d'un faisceau convergent. Le réseau de diffraction focalise un ordre spectral requis sur un groupe de détecteurs d'ultraviolets (24). Habituellement, c'est le spectre du premier ordre qui est placé. Le détecteur de cette invention peut être portatif.
