The property of presenting different colors by transmitted light, when viewed in two different directions, the colors being unlike in the direction of unlike or unequal axes.
Literally means "two colors". A mineral that exhibits one color when viewed from one angle but a different color when viewed from a different angle is said to display dichroism.
The appearance of one color in relfected light and another with tranmitted light. Such as with gold fuming, the glass has a metallic gold appearance in reflected light, but appears blue, pink, or violet from light shining through it from the back. Reference to glass that shows different colors from different lighting.
The property of some materials to absorb light waves oscillating in one plane, but transmit light waves oscillating in the perpendicular plane.
pleochroism of a crystal so that it exhibits two different colors when viewed from two different directions
A double refractive mineralâ€(tm)s ability to display two different colors or color shades when viewed from different directions. (See also “Trichroism.â€)
Is the property of having more than one color
It literally means "two colors." A mineral displaying different color from different angle while viewing such is said to display dichroism.
the property of a substance to show two different effects under different viewing circumstances. For example, some colors appear different when applied using horizontal strokes than when applied using vertical strokes.
The property possessed by some crystals of exhibiting two different colors when viewed from different angles. See Alexandrite, Ammolite, Iolite, Opal.
The characteristic of some gems to appear to be different colors, or different shades of the same color when the stone is viewed from different sides.
The ability of certain gems to display a second color when viewed from a different angle.
Two different imaginary parts of the refractive index for electromagnetic waves identical except for their states of ( orthogonal) polarization. By orthogonal is meant that the waves have opposite handedness, the same ellipticity, and the major axes of their vibration ellipses are perpendicular to each other. The most general dichroism is elliptical, specific examples of which are linear and circular. The dichroism of a medium originates from its asymmetry. See birefringence.
The exhibition of one color in refracted light and another in transmitted light (such as in gold fuming, where the glass looks like metallic gold in reflected light, but pink, violet or blue when light shines through from behind). Also refers to glasses which appear different colors under different lighting conditions.
