Title (EN) PHOTOMETER APPARATUS
(FR) APPAREIL DE PHOTOMETRIE
Abstract: front page image
(EN)A sample holder and shutter assembly (20) for photometers in which a stationary sample chamber body (40) is mounted in close proximity to a photosensitive device (18). A light path is provided from the sample chamber (53) to the photosensitive device (18) and shutter means is provided for selectively interrupting and opening the light path between the photosensitive device (18) and the sample chamber (53) without moving the sample chamber. Heat exchange means including a heat pump (63) and a heat reservoir (68) are provided for maintaining a desired temperature in the sample chamber (53). The sample chamber body (40) is thermally connected to said heat pump (63) and is preferably thermally isolated from the means mounting it. In one embodiment, the heat pump (63) and heat reservoir (68) are flexibly connected.
(FR)Un assemblage de support d"echantillons et d"obturateurs (20) pour photometre comprend un corps de chambre d"echantillon nage fixe (40) monte a proximite d"un dispositif photosensible (18). Un passage lumineux est prevu de la chambre d"echantillonnage (53) au dispositif photosensible (18) et un obturateur est prevu pour fermer et ouvrir de maniere selective le trajet de la lumiere entre le dispositif photosensible (18) et la chambre d"echantillonnage (53) sans deplacer celle-ci. Des moyens d"echange de chaleur comprenant une pompe de chaleur (63) et un reservoir de chaleur (68) sont prevus pour maintenir la temperature desiree dans la chambre (53). Le corps de la chambre d"echantillonnage (40) est relie thermiquement a la pompe de chaleur (63) et est de preference isole thermiquement des moyens ou il est monte. Dans une realisation, la pompe de chaleur (63) et le reservoir de chaleur (68) sont relies de maniere souple.
