The Field of View on a microscope determines the size of the imaged area. It gains importance when you want to measure specifics such as densities -for example, an experiment to estimate the density of cells in a solution. To get the answer, you have to acquire an image of a Field of...
Knowing a compound light microscope's field of view (FOV) allows you to determine the approximate size of objects too small to measure with a standard ruler. To calculate field of view, you need to know the magnification and field number of the microscope's lens currently in use. Divide th...
Switch to the next highest objective lens and reposition the slide ruler to measure the field of view. Repeat this for all the objective lenses. Place the specimen on the stage and select the most appropriate objective lens. The objective lens that allows you to fill most of the field of v...

Depth of field- vertical distance, from above to below the focal plane, that yields an acceptable image Field of view- area of the specimen that can be seen through the microscope with a given objective lens Focal length- distance required for a lens to bring the light to a focus (usually...
Here is an example to demonstrate these advantages. The EvidentOLS5000 microscopewas used to measure the surface roughness of a G21 needle (outer diameter: 0.8 mm). The image below shows data from a single field of view (measurement area: 256 µm × 256 µm, magnification: 1,080X):...
We measure it in units of cycles (waves) per second, or hertz. The frequency of visible light is referred to as color, and ranges from 430 trillion hertz, seen as red, to 750 trillion hertz, seen as violet. Again, the full range of frequencies extends beyond the visible portion, from...
Pretrained neural network models for biological segmentation can provide good out-of-the-box results for many image types. However, such models do not allow users to adapt the segmentation style to their specific needs and can perform suboptimally for te

Nanotechnology is the science of manipulating matter where at least one dimension is in the nano-scale. Nanotechnology is a very promising field to the medicinal and pharmaceutical sectors, hence, it plays an important role in enhancing humanity’s quality of life. Nanotechnology has many application...
