dichroic

dichroic

A dichroic crystal splits a beam of light into two distinct colors.

Definition
  1. Adjective:
    • Exhibiting dichroism: "dichroic" describes a material, especially a crystal or an optical filter, that displays two different colors when viewed from different directions, or that transmits or reflects light of two distinct wavelengths.
    • Relating to dichroism: Pertaining to the property of splitting light into two beams of different colors, as seen in certain minerals or specialized glass.
Usage Examples
  • (It shows two different colors depending on the viewing direction.)
  • (A filter that reflects one color and transmits another.)
  • (They exhibit two distinct colors due to their crystal structure.)
Advanced Usage

  • "Dichroic glass": a type of glass that reflects light in two different colors, often used in jewelry and decorative art.

    • The pendant was made from dichroic glass, shifting from gold to purple as it moved. (The glass changes color based on the angle of light.)

  • "Dichroic mirror": an optical mirror that selectively reflects one wavelength of light while transmitting others, used in lasers and scientific instruments.

    • The laser system uses a dichroic mirror to separate the green and red beams. (The mirror reflects green light but allows red light to pass through.)
Variants and Related Words

  • Dichroism (n): the optical property of a material that causes it to appear in two different colors depending on the polarization or direction of light.

    • The dichroism of the crystal was studied under a polarizing microscope. (The property of showing two colors was analyzed.)

  • Dichromatic (adj): having two colors; often used for color vision deficiency (dichromacy) rather than optical materials.

    • This species of bird is dichromatic, with males and females having different plumage colors. (It shows two distinct color patterns.)
Synonyms
  • Birefringent: showing double refraction (related but not identical; birefringence often causes color effects).
  • Polychroic: exhibiting multiple colors (less common; dichroic specifically refers to two colors).
Related Idioms
  • No common idioms use "dichroic," as it is a technical term in optics and mineralogy.
