ACD65, Fcw, TL84, Ultralume
-
D50, D60, D75, F02, F07, F11, ILA, and ILC
Typical Materials Tested Include:
Awning fabrics
Have your awning materials tested for spectral transmission of solar light to ensure they do not transmit high levels of harmful wavelengths. Testing for UVA, UVB, UVA+B and visible ranges are available.
Garment fabrics
We can expose fabrics used for outdoors to measure the amount of radiation that is allowed to pass through by the particular material.
Display cases
Spectral transmission through the glass or plastic covers of display cases and cabinets is measured to assess the amount of radiation that may reach the exhibits enclosed, and assess the potential risks of fading or other damage that may be caused as a result.
Optical Filters
Have your optical filters measured to ensure that they are performing properly, and that they are blocking or transmitting the spectrum within specification.
Medical Packaging
Test your medical packaging materials for the effects of spectral radiation when stored on shelves under artificial light, or from natural sunlight passing through windows.
