摘要： There is provided a temperature measurement method for measuring a temperature of an ultraviolet light transmittance member transmitting ultraviolet light. The method includes: detecting ultraviolet light transmitted through the ultraviolet light transmittance member using a spectroscopic measurement unit, and obtaining an absorption edge wavelength of the ultraviolet light transmittance member; and deriving a temperature of the ultraviolet light transmittance member on the basis of the obtained absorption edge wavelength.

摘要： A photocurable composition which can be used to manufacture a three-dimensional object that is formed by stacking a plurality of layers on top of each other, from which the three-dimensional object having excellent transparency, a high glass transition temperature, and a high hardness can be formed, and which exhibits a high curing rate. The photocurable composition is a photocurable composition used to manufacture a three-dimensional object that is formed by stacking a plurality of layers on top of each other. The photocurable composition contains a monofunctional monomer having a polycyclic aliphatic group, a polyfunctional monomer, an alcohol, and an acylphosphine oxide photopolymerization initiator.

摘要： A method of inspecting a synthetic silica glass molded body includes: irradiating the synthetic silica glass molded body with a spectrum line of an Hg lamp having a wavelength of 248 nm; measuring light emitted by the synthetic silica glass molded body; and a procedure which may include screening a portion which satisfies a condition that a ratio of the bright line intensity and the fluorescent light intensity is of a certain value or less, or which may include determining whether a condition that a ratio of a minimum value and a maximum value of a measured fluorescent light intensity is in a certain range is satisfied or not.
