objektívátmér
Objektívátmér refers to the diameter of the objective lens or mirror in an optical instrument, such as a telescope or microscope. This measurement is a critical factor in determining the instrument's light-gathering ability and resolution. A larger objective diameter allows the instrument to collect more light, which is essential for viewing faint objects or observing at high magnifications.
In telescopes, a larger objective diameter directly correlates to a brighter and more detailed image. For instance,
Similarly, in microscopes, the objective lens diameter influences the resolution, which is the ability to distinguish
The term "objektívátmér" is therefore a fundamental specification for anyone selecting or using optical instruments, as
