#instrument definition
- Achromatized — Having undergone the process of achromatization; an optical system, objective, or lens assembly color-corrected to prevent light dispersion and the formation of parasitic colored fringes. In a technical sense, it describes the final state of a precision device whose sphero-chromatic aberrations have been minimized according to industrial standards.
- Adaptometer — A laboratory apparatus used in ophthalmology and physiology to measure the speed and capacity of the eye to adapt to darkness or sudden variations in light intensity. The device projects precisely controlled light stimuli, enabling the determination of the retinal adaptation curve and the diagnosis of night blindness or other photoreceptor cell dysfunctions.
