Physiological optics
As well as other related topics.

Electron optics:
All methods strongly related to light optics, e.g. geometrical electron optics, imaging theories and methods, GRIN optics, geometrical aberration
Instrumentation and equipments for guiding, focusing and imaging of charged particles, spectrometers and beam lithography
Image reconstruction and analysis, holographic methods
It publishes original papers and short notes on theoretical and experimental research in English. OPTIK addresses itself especially to scientific and technical working specialists in this field.
