Abstract: The present invention provides a method of increasing the strength of a glass substrate for optical filters and a tempered-glass optical filter using a tempered glass substrate manufactured using the same, in which the glass substrate for optical filters is subjected to chemical tempering so that a compressive stress (CS) and a depth of layer (DOL) of the glass substrate are adjusted to increase the bending strength thereof.

Abstract: 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.
