摘要:
The invention relates to a method for adjusting the pupillary delay compensation of a convergent or divergent beam. The method comprises the steps of placing a device comprising an afocal system with one or more optical passive components arranged on the propagation axis of said beam, wherein one at least of said components is a diffractive focalising component, and displacing the device along the beam propagation axis until the desired pupillary delay compensation is achieved, said compensation being the algebraic sum of the pupillary delays of each passive optical component of the afocal system and being comprised in a range of values whose limits depend on the particular combination of the optical components selected for realising the afocal system of the compensation device.
