Exposure Standards

Luzchem Research, Inc. produces and distributes freely these standards as a service to scientists involved in research in photochemistry, photobiology and photostability. These standards are available on Luzchem's website so that references to any of our standards can be used to define exposure conditions and allow other scientists to replicate irradiation conditions readily. Luzchem has measured these exposure standards using a NIST traceable spectroradiometer. To our knowledge, spectral information is accurate within the experimental uncertainty of 1 nm.
