FIELD: optical instrument engineering.
SUBSTANCE: device can be used for designing optical circuits of high-resolution laser printers. System has laser, focusing element, collimating element, polygon, and astigmatic singlet. Range of possible numerical meanings of all free parameters of the circuit is determined preliminary from the developed system of algebraic equalities and inequalities while taking properties of laser radiation into account.
EFFECT: reduced time and cost for designing of optical system; widened range of tolerance when making a singlet.
