Isuzu ISK Colored Glass Heat Absorbing Filters reduce the amount of heat transmitted through an optical system and are ideal for high intensity light sources and medical applications. These filter glasses provide maximum transmission over the visible spectrum while minimizing the transmission of infrared light. Isuzu ISK Colored Glass Heat Absorbing Filters can also be utilized as ultraviolet bandpass filters, as all glass types feature high UV transmission or as shortpass filters, to pass the visible and block the IR. Isuzu ISK Colored Glass Heat Absorbing Filters feature high optical density at 1064nm and are less hygroscopic than comparable heat absorbing filters. We recommend using a cooling fan with any of our heat absorbing products to reduce stress associated with excessive heat.
