Thermal insulation glass filter KG1 KG2 KG3 KG5

---

Heat-absorbing filters made of KG1, KG2, KG3, KG4 and KG5 filter glass materials allow thermal energy to be removed from optical systems in a targeted manner. Due to its high optical density in the infrared wavelength range, this filter is also known as heat-absorbing glass. This glass filter is commonly used in lighting systems to absorb the heat energy emitted from the light source. While absorbing heat, glass filters also provide a high, relatively neutral transmission of visible light.
