OGC manufacture cold mirrors for projectors that transmit heat rays and reflect only visible light, and UV reflectors for exposure equipment that reflect only ultraviolet rays.
We use two types of glass base material; aluminosilicate glass “XHK” and low-expansion glass ceramic “TCM” depending on lamp wattages.
The reflective coating is formed by the vacuum deposition method and the IAD method.
