What are the differences between brightfield, darkfield and phase contrast?
These are three different microscopic techniques. Brightfield is the standard technique, which retains the natural colors of the specimen. the specimen appears dark on a bright background. Brightfield is suitable when you want to see the natural colors of the specimen or when you observe stained samples. Bright field microscopy is the conventional technique. It […]
Safety issues in Microscopy
Safety issues in microscopy are not only relevant to amateur microscopists, but also for teachers who want to conduct basic microbiological and microscopic work in a school laboratory. In this case the organisms are alive and depending on the type of organism, they may pose a possible health hazard. The post addresses some of the safety issues that should be taken into consideration.
A Projection Screen for Microscopes
Projection screens are useful if several people want to look at the specimen. The screen is mounted on the trinocular head instead of a camera.
Setting up a Home Laboratory for Microscopy
Why a home lab? For someone who wants to observe ready-made permanent slides or an occasional pond water sample, a fully equipped home laboratory may not be necessary and somewhat of an overkill. In this case it is sufficient to find a reasonably dust-free place to store and operate the microscope. The microscope can then […]
Determining Size in Microscopic Images
Our Biology curriculum in school requires students to be able to calculate the size of cells and other structures from light micrographs, which have a scale bar. It’s probably more interesting for students to actually take the light micrographs themselves. It is not difficult to determine the size of cells and other structures in light […]
