Heat Absorbing Optical Filter Glass
Heat Absorbing Optical Filter Glass from Stock
Heat absorbing filter glass, which is also classified as a shortpass filter, exhibits high transmission in the visible range and effective absorption of infrared radiation in the long wave spectral region. Heat absorbing filters are used wherever good transmission in the visible range is required along with effective absorption of undesirable heat radiation. This makes this glass an excellent heat absorption filter, or heat protection filter. These filters can be used as heat protection filters in photocopiers, in hospital operating room lamps, and also as components in laser eye safety glasses and windows.
