A method for producing an organic microdisk structure, which is characterized by comprising: a cladding layer formation step 1 wherein a cladding layeris formed by printing a first inkthat contains a fluorine-containing hyperbranched polymer on a substrateby an inkjet method; a core layer formation step 2 wherein a core layeris formed by printing a second inkthat contains a laser dye and a triazine-based hyperbranched polymer containing no fluorine on the cladding layerby an inkjet method; and an etching step 3 wherein the cladding layeris etched using a solventthat dissolves only the fluorine-containing hyperbranched polymer. Consequently, an unconventional novel method for producing an organic microdisk structure with use of an inkjet method is able to be provided.

A laser light source for emitting excitation light, a sample case, a photomultiplier tube, a fluorescence collecting optical system and so forth are embedded in a resin material that is transparent to the excitation light and the light including fluorescence emitted from a sample. The resin material is provided in at least part of a light path that guides the fluorescence in the fluorescence collecting optical system, and this resin forms a housing that holds the laser light source, the fluorescence collecting optical system, the photomultiplier and so forth. A pigment having wavelength characteristics for absorbing the excitation light, Raman light generated from the resin, and so forth is contained substantially in a uniform manner in a resin region that surrounds the light path through which the excitation light and the light including the fluorescence pass.

A light measuring arrangement maintains the initial filtering function of an optical filter having a dye dispersed therein. The light measuring arrangement includes a measuring unit configured to measure an intensity of light emitted from a measurement target at a predetermined wavelength. The light measuring arrangement also includes the optical filter unit having the dye. The light measuring arrangement also includes a dye diffusion restricting unit configured to restrict diffusion of the dye from the optical filter unit. The optical filter unit constitutes part of an optical path for the light traveling from the measurement target to the light measuring unit.
