What are the key aspects of microscope image formation?
The formation of microscope images is the image generated between the image and the intermediate image plane through direct light in an optical microscope, and the occurrence of functional invariance and diffracted light in the specimen.
That is, the conjugate sample in the image generated by the objective lens, which means that each image point corresponds to a point in the sample that is related to the geometric shape of the intermediate plane.
Optical aberration refers to the deviation from Gaussian optics under ideal conditions. The optical train of a microscope usually suffers from these five common distortions: spherical, chromatic, difference in field curvature, and astigmatism. Geometric distortion is discovered by stereomicroscopes and is often a problem encountered in zoom lens systems.
The length of the mechanical tube of an optical microscope is defined as the distance from the top edge of the observation tube when the eyepiece is inserted into the target installed from the opening of the nasal turbinate.
Most microscopes have a fixed range of tube lengths, which depend on the manufacturer and application.
The main application areas and functions of stereomicroscopes
A stereomicroscope is a microscope with two complete optical paths that provides a sense of three dimensionality when observing specimens. It has many uses and is a type of microscope with a sense of three dimensionality. Stereoscopic microscopes can be equipped with digital imaging devices to become digital stereomicroscopes.
In this way, it has more advantages in observation:
1. It can reduce eye service and achieve multi person synchronized preview at low cost.
2. You can save the observed images and distribute them to each relevant section for viewing.
3. It can perform other functions such as video recording and measurement. Stereoscopic microscopes are easy to operate, with a magnification typically ranging from 7X to 42X and a maximum magnification of 180X.
