Our product heat absorbing filter GRB2 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. To prevent a filter glass from being broken by rapid heating or cooling, this optical filter can be also provided as a thermal toughening tempered glass.
Main Application: Medical equipment, operating room, slide projector, slider and projector.
Type：GRB2 Thickness：T=3.00MM
