birefringent

Thân thiện

A clear calcite crystal rests on a page of printed text, showing birefringent double images.

Definition

1. Adjective:
   • Relating to or characterized by double refraction: A property of certain transparent materials that causes a single ray of light to split into two rays, each traveling at a different speed and in a slightly different direction. This effect occurs because the material has different refractive indices for light polarized in different directions.

Examples of Usage

• Adjective:
  • Calcite is a highly birefringent mineral, which is why objects viewed through it appear double.
  • The birefringent properties of the crystal were analyzed using a polarizing microscope.
  • When placed between crossed polarizers, the birefringent sample displayed bright, colorful patterns.

Advanced Usage

• "Birefringent material": A specific substance that exhibits birefringence.
  • Quartz is a common birefringent material used in optical devices.
• "Birefringent filter": An optical filter that uses birefringence to select specific wavelengths of light.
  • The astronomer used a birefringent filter to observe a specific spectral line from the sun.

Variants and Related Words

• Birefringence (noun): The phenomenon or property of being birefringent; double refraction.
  • The birefringence of the plastic film indicated it was under stress.

Synonyms

• Double-refracting: Having the property of double refraction.
• Anisotropic (in optics): Having physical properties that differ based on the direction of measurement, which can cause birefringence.
