Heat Absorbing Filters

Heat absorbing glass filters are made from heat absorbing filter glass material, absorbing the infrared (IR) region and dispelling 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 filter, passing the visible and blocking the IR.

Used widely for projectors, illumination equipment and scientific instruments.

UQG optics Heat absorbing filters are made as diameters and squares to a standard stock range or custom made.
