forstørrelsesorden

Forstørrelsesorden, often translated as "magnification order" or "enlargement order," is a concept that relates to the relative size of objects when viewed through optical instruments like telescopes or microscopes. It's not a formal scientific term with a precise definition but rather a descriptive way to compare how much an instrument enlarges an object's apparent size.

When discussing forstørrelsesorden, one is generally referring to a qualitative assessment of magnification. For instance, a microscope typically has a much higher forstørrelsesorden than binoculars. This means that to see very small, detailed structures, one would use a microscope, while to observe distant objects with a moderate degree of enlargement, binoculars would be more suitable.

The concept is also relevant when comparing different types of telescopes. A refractor telescope might have a different forstørrelsesorden capability than a reflector telescope of similar objective lens or mirror diameter, depending on the eyepiece used. The practical limit of magnification for any optical instrument is also often discussed in terms of forstørrelsesorden, where exceeding a certain point leads to a blurry or unusable image, even if the magnification is technically higher. Essentially, forstørrelsesorden helps users understand the intended use and capability of an optical device in terms of its ability to make objects appear larger.
