A system of analysis with the naked eye and by fluorescence of a field in an illuminated area comprising a periodically-excited first low-remanence white light illumination source; a second light source for exciting fluorescent elements located in said field, active at least during part of the time periods when the first source is off; and a fluorescence analysis device active during time periods when the first source is off and the second source is on.

The invention relates to a method for detecting clusters of biological particles () on a surface (), comprising steps that involve: a. determining (E) a topographical representation () of said surface; and b. detecting (E, E), on said topographical representation, at least one contour defining a region that is likely to correspond to a cluster of biological particles.

The invention pertains to a process and to a device for positioning an optical component between two optical fibers furnished at their end with lenses comprising: drilling a support in such a way as to fix therein a capillary tube whose inside diameter is designed to slip an optical fiber thereinto, fixing the capillary tube in the drilling of the support, making a blind cut of the support and of the capillary tube, in such a way as to separate the capillary tube into two parts, a first plane face of the cut being perpendicular to a longitudinal axis of the capillary tube, positioning the component on the first plane face, positioning an optical fiber in each of the parts. The device comprises a support through which is fixed a capillary tube, the support comprising a cut so as to separate the capillary tube into two parts. The cut comprises a first plane face perpendicular to a longitudinal axis of the capillary tube. The component is positioned on the first plane face.

The invention relates to tunable wavelength-selective optical filters for letting light of a narrow optical spectrum band, centered around an adjustable wavelength, to pass through and to stop wavelengths lying outside this band. More particularly, the invention relates to a process for the collective fabrication of optical filtering components, consisting in producing a plurality of optical filtering components on a transparent substrate. The process further comprises covering the plurality of components with a transparent collective cover, in optically testing each component individually, and in separating the various components from one another. The invention also relates to a wafer of components, comprising a transparent substrate on which a plurality of optical filtering components has been produced, a transparent cover () collectively covering the components. The wafer further includes means for individually testing each component.

A solid state photosensitive detector including a solid state photosensitive sensor associated with a converter designed to convert radiation to be detected into radiation to which the photosensitive sensor is sensitive. The photosensitive sensor includes one or more photosensitive elements connected to conductors and a passivation layer covering the photosensitive elements and the conductors to protect them. Between the passivation layer and the converter, a barrier is provided that is impermeable to at least one chemical species that is corrosive for the sensor, capable of being released by the converter during at least one chemical reaction. Such a detector may find particular application to radiation detectors for medical radiology.
