ogniskowymi

Ogniskowymi is the instrumental plural form of the Polish adjective ogniskowy, used to describe things related to a focus or focal length in technical contexts. The base noun is ogniskowa, referring to the focal length, the focal point, or the focal plane of an optical system. In optics and photography, ogniskowa is the distance from the optical center to the focal point and is a key parameter that determines magnification and field of view. Shorter ogniskowe values yield wider fields of view; longer ogniskowe values yield higher magnification and a narrower field.

The term ogniskowymi occurs in phrases describing multiple components with focal properties, e.g., soczewkami ogniskowymi or obiektywami ogniskowymi, meaning focal-length lenses or objectives. It is also used in microscopy (e.g., 40x or 100x ogniskowe objectives) and in astronomy (telescopes with long ogniskowe lengths). In everyday Polish usage, the form appears whenever listing several focal-related elements and the adjectives agree in instrumental case with the nouns.

Grammatical note: ogniskowymi is the instrumental plural of ogniskowy; other forms include ogniskowa (feminine singular), ogniskowy (masculine singular). The concept is strictly technical and context-dependent but commonly appears in texts about optics, cameras, microscopes, and telescopes.
