DT Photon

Precision Lighting for Cultural Heritage

The DT Photon series is the only lighting designed specifically for Cultural Heritage imaging and color reproduction. They provide preservation-grade spectrally accurate color reproduction, conservation-friendly UV-filtration and operating temperature, and industrial-grade build quality and longevity.

Both the 19″ DT Photon and 38″ DT Photon XL can be used for standard photographic lighting and used with any copy stand. The DT Atom was specialized designed to hold two 19″ DT Photon units, without the need for floor stands or ceiling mounts.

The DT Photon can also be placed under an object such as photographic film or a watermarked manuscript in order to provide transillumination. It fits in the interior cavity of the DT Atom or placed on the tabletop of any copy stand and used as the object-bearing surface; the top surface runs at 92 degrees Fahrenheit (33C), about the same as a human hand.

Made in the USA.
