Suurennuksella

Suurennuksella is Finnish for “under magnification” or “with magnification.” It is formed from the noun suurennus (magnification) plus the instrumental suffix -lla, indicating that something is viewed or presented using a magnifying instrument. The term is mainly used in scientific and educational contexts to describe observations or images produced when an object is examined through a magnifier, a microscope, or other optical devices.

In practice, suurennuksella is used to indicate the level of magnification, often in phrases such as suurennuksella 40x, 400x or 1000x, or as 40-kertainen suurennus. The total magnification depends on the combination of lenses (for example, eyepiece and objective in light microscopy) and is sometimes referred to as kokonaiset suurennukset.

A key related concept is that magnification is not the same as detail. High magnification can reveal larger images but does not by itself improve resolvability; resolution is determined by factors such as wavelength of light and numerical aperture of the optics. Consequently, practical observation at high magnification requires appropriate optical quality and sample preparation; otherwise, the image may appear enlarged but not more informative.

Suurennuksella is commonly encountered in biology, histology, mineralogy and other fields where specimens are studied at various scales. In Finnish texts it appears in lab manuals, textbooks, and captions describing microscopic or enlarged views. See also suurennus, mikroskopia, and resoluutio.
