An ophthalmic instrument including a light emitter, an optical system, and a control section. The light emitter includes a light source including at least one out of a first light source unit or a second light source unit that emits light for examining a subject eye. The light emitter is configured to emit light from the light source. The optical system guides light emitted from the light emitter onto a right-eye retina and/or onto a left-eye retina. The control section is configured to control the light emitter and the optical system such that the light is shone onto the right-eye retina and/or onto the left-eye retina.

Ophthalmic instrument, management method, and management device

A curable composition capable of manufacturing a cured product having a high refractive index is provided. The curable composition contains a polymerizable compound represented by formula (1) and inorganic particles. In formula (1), Lrepresents a divalent linking group, and the divalent linking group includes at least one of a divalent aromatic group, a divalent polycyclic aliphatic group and an alkylene group having an aromatic group, Ar represents an aromatic group, and R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents. 

Curable composition, cured product and optical member

A method of manufacturing an optical member includes a crystal growing step and a carving step. The crystal growing step includes melting a mixture of fluoride powder and a scavenger at a melting temperature of a melting point for the fluoride and above, and then crystallizing the melted fluid and further cooling down an obtained fluoride crystal in a temperature range from 1000&#xb0; C. to 900&#xb0; C. by a temperature decreasing rate in a range from 0.1 to 5&#xb0; C./hr. The carving step includes carving an optical member out of the fluoride crystal obtained in the crystal growing step such that the optical member is made of a fluoride crystal in which a maximum diameter dof scattering bodies existing internally and a quantity nof the scattering bodies per 1 cmsatisfy a condition represented by the following formula (1):0(cm). &#x2003;&#x2003;(1)

Optical member, method of manufacturing the same, and projection exposure system

An optical member of the invention is an optical member for photolithography used together with light having a wavelength of not more than 250 nm. The optical member is made of a fluoride crystal in which a maximum diameter d(cm) of scattering bodies existing internally and a quantity nof the scattering bodies per 1 cmsatisfy a condition represented by following formula (1):0&#x3c;&#x3c;6.5&#xd7;10(cm)&#x2003;&#x2003;(1).
