Heat Absorbing Filter

   A heat absorption filter has high transmittance in the visible region and is used as a filter that absorbs the heat rays of incident light.

The absorbed heat is radiated into the air around the filter, so in order to make this product effective, we recommend using it with an air cooling device.

The products in the catalog are uncoated, but we also accept special orders for heat reflective coating. For the coat simulation and price, please contact us.
