The lowest magnification on a microscope typically depends on the type of microscope being used. For a standard compound microscope, the lowest magnification is usually around 4x. This is achieved using the lowest power objective lens, which allows for a broader view of the sample and helps in locating areas of interest.
The 4x magnification provides a general overview of the slide, making it easier for the user to identify where to focus at higher magnifications, such as 10x or 40x. Some microscopes may also have a lower power objective, like 2x, but this is less common in standard laboratory settings.
Using lower magnification is essential in microscopy as it enables the examination of a larger field of view, which is crucial for initial explorations of the specimen. Once areas of interest are identified, higher magnifications can be utilized for detailed study.
