An apparatus for measuring transmissivity of a patterned glass substrate. A beam radiator radiates a laser beam. A collimation lens collimates the laser beam radiated from the laser beam radiator. A beam expander expands a size of the laser beam collimated by the collimation lens. A detector has a light-receiving section, which receives the laser beam that has passed through the patterned glass substrate after having been expanded by the beam expander. A measuring instrument measures a transmissivity of the patterned glass substrate using the laser beam received by the detector.

Apparatus for measuring transmissivity of patterned glass substrate

An apparatus for measuring transmittance which can realize reliability for measurement of the transmittance of a piece of patterned glass by post dispersion of light. The apparatus includes a light source which is disposed in front of an object that is to be measured, and directs light into the object. An integrating sphere is disposed in the rear of the light source and integrating light incident thereinto. The object is mounted on the front portion of the integrating sphere. A light dispersing part is disposed in the rear of the integrating sphere, and disperses light that has been integrated by and then emitted from the integrating sphere. An optical receiver is disposed adjacent to the light dispersing part, and receives light that has been dispersed by the light dispersing part.

Apparatus for measuring transmittance

An apparatus for manufacturing tempered glass. A transportation unit transports a glass substrate that is intended to be tempered. An ionizer ionizes alkali oxides in the glass substrate by radiating energy onto the glass substrate. A dielectric heating unit increases the temperature of the inner portion of the glass substrate in which the alkali oxides are ionized by the ionizer.
