Abstract: The present disclosure relates to a method for manufacturing end microlenses of individual optical fibers which are part of a bundle or a multi-core fiber, including depositing a drop of a photopolymerizable solution on a first end of the bundle; adapting the size of the drop; applying light centered on a predetermined wavelength onto a second end of the bundle in order to selectively polymerize the drop; rinsing the first end using a methanol solution in order to obtain a network of individual optical fibers, each one of which is provided with a microlens at the first end of the multi-core fiber, the microlenses being physically separated from one another. The disclosure additionally relates to a bundle of microlensed fibers obtained by the method, as well as to the use of such a bundle, for example in medical or multiplexed imaging and/or in the coupling of optical fibers.

Abstract: An imaging system for analyzing fluorescent molecules in a sample, including a confocal microscope device, has a support in contact with at least a portion of the sample. In the system, the support surface in contact with the sample is functionalized so as to reduce the observation volume of the microscope on the surface in the axial direction. The present disclosure also relates to various uses of such a system as well as to a method for analyzing fluorescent molecules in a sample, the method being implemented by such a system.
