(DE) TESTKARTE FÜR ANALYSEN
(EN) ANALYSIS CARD
(FR) CARTE D'ANALYSE
Abstract
(EN)
An analysis card (1) containing two mutually separate chambers (2, 3) separated by a frangible partition (7) that is arranged within said card and made of an absorbent and preferably plastic material for absorbing light energy having at least a predetermined wavelength $g(l), and converting it into heat energy capable of at least locally removing said material. Two cavities (8, 9) are provided on either side of the partition (7) and each communicate with or are included in a respective one of the two chambers (2, 3). A window (10, 11) made of a material transparent at least to said wavelength $g(l) is arranged opposite said partition (7) and defines therewith one (8) of said cavities, which is also known as an incident light beam (12) cavity.

(FR)
Carte d'analyse (1), dans laquelle sont ménagées deux chambres (2, 3) isolées l'une par rapport à l'autre, caractérisée en ce que les deux chambres sont séparées l'une de l'autre par une cloison (7), perforable, disposée au sien de ladite carte, en matériau absorbant, notamment matière plastique, absorbant une énergie lumineuse, ayant au moins une longueur d'onde prédéterminée $g(l), pour la transformer en une énergie thermique susceptible d'éliminer au moins localement ledit matériau, deux cavités (8, 9) sont ménagées de part et d'autre de la cloison (7), et sont en communication avec ou comprises dans respectivement les deux chambres (2, 3) respectivement, une fenêtre (10, 11) en un matériau transparent au moins pour la longueur d'onde $g(l) est disposée en vis-à-vis de ladite cloison (7), et délimite avec cette dernière l'une (8) desdites cavités, dite d'incidence d'un rayon lumineux (12).
