Heat Absorbing Filters
Heat absorbing glass filters are used as heat controlling absorbing filters. IR absorbing the infrared region and dispel heat into the air. Filters can be toughened/tempered to place the surface in tension to increase the resistance to thermal shock and breakage. These heat filters are also supplied un-toughened when the characteristics of the filter are suitable for the application. It also acts as a short pass filters passing the visible and blocking the IR.
