IR filter / Heat-reflecting filters
Infrared filters (Heat-absorbing filters), commonly known as "IR filter" are often used for generating a light similar to sunlight (artificial sunlight) or in order to remove the unwanted rays in the near-infrared region (NIR) from the light beam.
The IR3 heat reflecting filter should allow the visible part of light to pass through without any change in colour; this can be clearly seen in the photo.
The image clearly shows that the heat-reflection filter transmits the light without any colour distortion. On the contrary, the heat component of the light is reflected by this IR filter.
Glass types and sizes
The IR filters are offered in the following materials / thicknesses / sizes
In addition, we also provide even smaller filter sizes with less material thickness. We can cut the filters round as well as in any other shape – please see Customised Glass Cutting Service.
