Unique Properties of AgGaSe2 Crystals

AgGaSe2/AgGaS2 crystals are sensitive to Ultraviolet radiation, even UV light in your inspection source will have influences on the properties of these material, effects may show as transmission decrease or surface quality damaged.

Well-kept AgGaSe2 crystal’s surface quality seen by naked eyes

Exposed under nature light for several days’ AgGaSe2 surface quality seen by naked eyes.

From this contrast test, we saw the Ultraviolet radiation can do obvious influence on the surfaces. Due to this unique properties, we suggest that customers should keep this crystal away from UV light before coating. If inspection is necessary, please use an optical filter to filter out the UV light from the light sources.

Well-kept AgGaSe2 crystal’s surface quality seen by 100 times magnifying equipment.

Exposed under nature light for several days’ AgGaSe2 surface quality seen by 100 times magnifying equipment.

e.g. AgGaSe2 crystal’s surface quality damaged:
A series experiment turns out a short time expose under inspection light the surface become shadow and scratched. And the results of these phenomenons may become observable in hours or days.
