What does dichroic mean?
The term dichroic refers to materials or objects that exhibit dichroism, the property of showing different colours under different lighting conditions or when viewed from different angles. This phenomenon is often observed in certain glasses, minerals, and biological tissues. Dichroic materials are prized for their unique optical properties, making them useful in applications ranging from optical filters and prisms to artistic sculptures and decorative objects. The word dichroic is derived from the Greek words 'di' meaning two and 'chroma' meaning colour. Understanding and harnessing the properties of dichroic materials has led to innovations in fields such as optics, photonics, and materials science.
adjectiveHaving or exhibiting dichroism; showing different colours in different lights or when viewed from different angles.
- Exhibiting dichroism
- Having two colours
"The dichroic glass filter changed colour dramatically as the light source shifted."
"The dichroic mirror reflected different colours depending on the angle of incidence."
"The butterfly's dichroic wings shimmered in the sunlight."

Etymology of dichroic
The word 'dichroic' originates from the Greek words 'di', meaning two, and 'chroma', meaning colour. This etymology reflects the material's ability to display two colours under different conditions. The term has been used in the context of optics and materials science since the early 19th century.
Usage notes
Often used in technical contexts, such as optics and materials science, but also in artistic and design applications.
