摘要： Disclosed is an optical-filter-cell-array structure and a method of manufacturing the same. An optical filter which includes an optical filter layer for blocking light of a specific wavelength formed on an upper side or a lower side of a tempered glass substrate is provided in the form of a cell array. The method includes forming a sheet-cutting part according to the form of a cell array on a mother glass substrate, tempering the mother glass substrate so that a lateral side of the mother glass substrate is tempered through the sheet-cutting part while an upper side and a lower side of the mother glass substrate are tempered, and forming an optical filter layer on the upper side or the lower side of the mother glass substrate.

摘要： The present invention relates to a manufacturing method for a camera window and a camera window manufactured thereby. A conventional camera window is configured such that an etching pattern is provided on a back surface of a glass sheet, and a deposition layer is provided on the etching pattern, thereby improving reflectivity, whereby indirect external recognition of the etching pattern is performed, but in the present invention, a distinctive pattern is provided on a front surface of a glass sheet such that direct external recognition of the pattern is possible, whereby it is possible to recognize a distinctive pattern line.

摘要： Disclosed is a near-infrared filter. The near-infrared filter includes a filter-support-seat body including a quadrangular pillar cell region and a dummy region which surrounds the cell region and which is gradually reduced in size from the cell region, and an optical-filter-subdivision layer covering the cell region and the dummy region at a front side and a rear side of the filter-support-seat body based on the path of a light beam which is incident on the front side and penetrates the rear side in the filter-support-seat body. The dummy region has a chamfered side that is slanted obliquely in at least one side of the front side and the rear side of the filter-support-seat body. Further, a method of manufacturing the near-infrared filter is disclosed for each process step.
