Colored Glass Filters

COLORED GLASS FILTERS

Heat Absorbing Filters (HA)

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.

Application: Medical

Images: HA30

[Remark]
To prevent a filter glass from being broken by rapid heating or cooling, this filter can be also provided as a thermal toughening tempered glass.
