An infrared optical filter may include a glass ceramic layer, a multilayer oxide thin film formed on a first surface of the glass ceramic layer, and a low reflectivity coating layer formed on a second surface of the glass ceramic layer.

Infrared optical filter having glass ceramic layer comprising 19-20% potassium oxide

A transparent substrate with a multilayer anti-glare coating includes a transparent substrate; a first coating layer formed on the transparent substrate and being formed of a first dielectric layer having a refractive index of n1; a second coating layer formed on the first coating layer and being formed of a metal oxide layer having a refractive index of n2; a third coating layer formed on the second coating layer and being formed of a second dielectric layer having a refractive index of n3; and a fourth coating layer formed on the third coating layer and being formed of a third dielectric layer having a refractive index of n4. The refractive indexes of the coating layers satisfy: n1=n3&#x3e;n2&#x3e;n4.

Transparent substrate with multilayer anti-glare coating

A planar lighting mirror in which nano-patterns are formed on an entirety or at a specific local area of a mirror surface of a mirror glass and a light source is disposed around the nano-patterns to be used like a mirror in normal operation. In particular, when the light source is activated, the entirety or the specific local area of the mirror surface with the nano-patterns formed thereon planarly emits light from the light source which flows into the side of the mirror glass so as not to deteriorate a mirrors reflective functions.
