dichroism

 [di´kro-izm]
the quality or condition of showing one color in reflected and another in transmitted light. adj., adj dichro´ic.

di·chro·ism

(dī'krō-izm),
The property of seeming to be differently colored when viewed from emitted light and from transmitted light.
[G. di-, two, + chrōa, color]

di·chro·ism

The property of seeming to be differently colored when viewed from emitted light and from transmitted light.
[G. di-, two, + chrōa, color]

dichroism

Property exhibited by certain transparent substances of producing two different colours depending upon the thickness of substance traversed, the directions of transmission of light and/or viewing, the concentration of the substance, etc. The most common example is that of crystals (e.g. tourmaline) that absorb unequally the ordinary and extraordinary rays. See anisotropic; dichroic crystal; pleochroism.
