Schott KG filter glass types KG 1, KG 2, KG 3, KG 4, and KG 5 exhibit high transmission in the visible and effective absorption of infrared radiation (heat radiation) in the long wave spectral region and therefore make excellent heat absorption filters (heat protection filters). They are used, for example, in slide projectors to protect the heat-sensitive slides from too great thermal load. These filters are also used as heat protection filters in photocopiers.

   An additional application area is the use of these filters in operating room lamps. The essentially colorlessness of the KG filters in the visible spectral range hinders any undesirable color falsification in operating rooms.

   In general, it can be said that the heat protection filters of the KG group can be used wherever good transmission in the visible is required with simultaneously effective absorption of undesirable heat radiation. 

   The filter glass types are listed below.  To view the linear transmission curves and data sheet for each, simply point and click on the glass type of your choice.
