What are the main points of microscope image formation?
The formation of the microscope image is the image generated between the image and the intermediate image plane through the direct light in the optical microscope, and the occurrence of the specimen with the invariant function and diffracted light in the specimen.
That is, the image produced by the objective is a conjugate specimen, which means that each image point is related to the geometry of the midplane to a corresponding point in the specimen.
Aberrations are deviations from Gaussian optics under ideal conditions. The optical train of a microscope is usually subject to these five common aberrations: they include spherical, chromatic, field curvature, and astigmatism. Geometric distortion is found in stereomicroscopy and is generally a problem frequently encountered in zoom lens systems.
The length of the optical microscope mechanical tube is defined as the distance from the top edge of the observation tube where the eyepiece is inserted into the mounted objective when the nosepiece opening is in place.
Most microscopes have a fixed range of tube lengths, these are manufacturer and application dependent.
Microscope Maintenance
The use of a dust cover is the most important factor in keeping the microscope in good mechanical and physical condition. If the shell of the microscope is stained, it can be cleaned with ethanol or soapy water (no other organic solvents are used for cleaning), but do not let these cleaning fluids penetrate into the microscope, causing short circuit or burning of the electronic components inside the microscope. Keep the place where the microscope is used dry. When the microscope works in a humid environment for a long time, it is easy to increase the chance of mildew. Therefore, if the microscope has to work in these high humidity environments, it is recommended to use a dehumidifier. In addition, if you find fog or mildew on the surface of the optical components, please contact professionals immediately for professional maintenance of your microscope.
