Our products heat absorbing filters GRB1, GRB3 are respectively equivalent to optical filters KG2, KG3 of Germany Schott and optical glass HA50, HA30 of Japan Hoya.

After toughening, the temperature resistance and hardness of the heat absorbing glass can be increased. Material: Insulating glass prominent feature is the high visible light transmission and wide absorb infrared range (especially for 1064nm infrared absorption), who require high light intensity but require filters to remove heat can occasion, application of 200nm to 2500nm spectral range of a full range of optical glass. Our Heat Absorbing Filters feature high transmittance in the visible region and good absorption of heat rays (infrared rays). They efficiently absorb thermal radiation emitted from light sources and are highly effective when employed for slide projectors and illumination equipment.

Main Application: IPL beauty machine, projector, illumination equipment, distilling equipment, etc.
