Title (EN) VARIABLE-WAVELENGTH OPTICAL OUTPUT DEVICE
(FR) DISPOSITIF DE SORTIE OPTIQUE A LONGUEUR D'ONDE VARIABLE
Abstract: front page image
(EN)A variable-wavelength optical device includes galvano-scanners (12, 13) equipped respectively with a diffraction grating (8) for varying wavelength and light quantity and a shield member (11) such that they oscillate to vary wavelength quickly with light quantity kept constant. Such a device is useful particularly for fluorescent imaging of a biological sample. Light incident on the shield member (11) enters an optical fiber (10), through which the light irradiates a biological sample (SM) effectively.
(FR)Ce dispositif de sortie optique à longueur d'onde variable comporte des galvanoscanneurs (12, 13) équipés, respectivement, d'un réseau de diffraction (8), permettant de faire varier la longueur d'onde ainsi que l'intensité lumineuse, et d'un élément de blindage (11), de sorte que ceux-ci oscillent pour faire varier rapidement la longueur d'onde alors que l'intensité lumineuse reste constante. Ce type de dispositif se révèle des plus utile, s'agissant notamment de l'imagerie fluorescente d'un prélèvement biologique. La lumière incidente à l'élément de blindage (11) pénètre dans une fibre optique (10), celle-ci illuminant efficacement un prélèvement biologique (SM).
