Etymology
'isochromatic' originates from Greek combining forms: 'iso-' meaning 'equal' and 'chroma' (χρῶμα) meaning 'color', formed in modern scientific/Neo-Latin usage.
'isochromatic' was formed in Modern/Neo-Latin from Greek elements 'iso-' + 'chroma' and entered English as a technical compound in the 19th–20th century, becoming the English adjective 'isochromatic'.
Initially meaning 'equal in color' from its Greek roots, it has retained that basic sense but acquired a specialized technical meaning in optics and photoelasticity referring to lines or regions of equal optical retardation or equal principal stress.
