  • Publication number: 20200290268
    Abstract: A method of manufacturing an optical article, wherein an output light flux generating process of generating an output light flux by inputting a light from a light source to an output setting element having a repetition structure; a cured layer forming process of forming a cured layer at an irradiation area that is formed in correspondence with the output area by introducing the output light flux through a projection optical system into a container in which light-curable resin is contained and a stage is arranged and condensing the output light flux; and a stage moving process of moving the stage in a desired distance along the direction of the output flux propagating, are sequentially performed in this order and an irradiation variation process of varying the irradiation area in the cured layer generating process are further included, thereby the optical article is formed on a surface of the stage.

  • Publication number: 20200180214
    Abstract: A photocurable composition for three-dimensional stereolithography which has a lower viscosity and from which a cured product having a high refractive index is obtained, and a three-dimensional object formed by using the composition. The composition is a photocurable composition for three-dimensional stereolithography containing a fluorene monomer, a carbazole monomer, a diluent monomer, and a photopolymerization initiator, the carbazole monomer being contained in an amount of less than 30 wt % with respect to the total amount of the fluorene monomer and the carbazole monomer, and the diluent monomer being contained in an amount of at least 20 wt % with respect to total solids.

  • Publication number: 20160139020
    Abstract: The invention relates to an installation (1) for determining the diffusion profile of at least one molecule through skin, comprising: a microfluidic chip (4) comprising: a donor compartment (10) intended to contain a test solution comprising the or each molecule; a receptor compartment (12) intended to contain a receptor solution; and a membrane (14) with skin-mimetic barrier properties arranged between the donor compartment (10) and the receptor compartment (12) so that the test solution diffuses through the membrane (14) from the donor compartment (10) into the receptor compartment (12); and an analyzer (8) for measuring a physical parameter of the solution contained in the receptor compartment (12) as the test solution diffuses through the membrane (14), and said analyzer (8) being configured for measuring the physical parameter in the receptor compartment (12), the analyzer (8) being further configured for calculating the diffusion profile of the or each molecule through skin from the measured physi
