7 Απρ 2017 · This article about state of the art microscopes is part of the Science in Sci-fi, Fact in Fantasy blog series. Each week, we tackle one of the scientific or technological concepts pervasive in sci-fi (space travel, genetic engineering, artificial intelligence, etc.) with input from an expert.
1 Ιουλ 2020 · As science fiction writers, we’ve long been fascinated with the idea of scale. From the microscopic to the cosmic, the possibilities are endless, and the implications often mind-bending. But how do we deal with the challenges of scale, both in our imaginations and in real-world science?
24 Δεκ 2022 · Magnification is the ability to make small objects seem larger, such as making a microscopic organism visible. Resolution is the ability to distinguish two objects from each other. Light microscopy has limits to both its resolution and its magnification.
19 Ιαν 2023 · In microscopy, the term “resolution” is used to describe the ability of a microscope to distinguish details of a specimen or sample. In other words, the minimum distance between 2 distinct points of a specimen where they can still be seen by the observer or microscope camera as separate entities.
Microscope resolution is the amount of detail that can be resolved from the light being refracted through a specimen and presented to the observer through a microscope. Resolution can also be thought of as the minimum distance between two distinct points that can be distinguished by the observer.
Scientists use a series of conventions when labelling microscope images. They include information about the magnification of the image (for example, 600x) as well as a scale bar, which acts as a ruler and indicates the true size of the object.
The resolution of a microscope objective is defined as the smallest distance between two points on a specimen that can still be distinguished as two separate entities. Resolution is a somewhat subjective value in microscopy because at high magnification, an image may appear unsharp but still be resolved to the maximum ability of the objective.
