Dichroic Glass — Transmitted and Reflected Complementary Colours
41.08 د.ك
Dichroic glass photographed in simultaneous transmitted and reflected light — the glass transmitting green while reflecting magenta, its metallic oxide coating producing the complementary colour pair through interference effects.
Description
Dichroic glass — glass coated with multiple nanometre-scale layers of metal oxides — transmits one colour while reflecting its complement through thin-film interference. The transmitted and reflected colours are not additive but complementary: a dichroic glass that transmits green reflects magenta, one that transmits gold reflects violet. This image was made by positioning a dichroic glass sheet at the boundary between a transmitted light source (backlight) and a reflected light source (front light), using the glass itself to separate its complementary colour pair into adjacent zones within a single image. The left half of the frame shows the transmitted green light passing through the glass from the backlight; the right half shows the reflected magenta from the front light on the same glass surface. The sharp boundary between the two colour zones occurs at the glass edge, where both effects simultaneously transition.
