Optical Failure Analysis of Microscopes
The dual images of the microscope do not overlap. In binocular observation, sometimes there may be a phenomenon of non coincidence of the two images. The occurrence of non coincidence of the two images does not care whether it is due to inconsistent compensation of the lengths of the two barrels. The difference in magnification between the two eyepieces is significant, and the position of the binocular prisms is moved due to vibrations during use or transportation. For the first two reasons, they are calibrated and selected at the factory, and can be solved by paying attention to the methods and matching during use.
The third reason for microscopes is quite common. At this time, the binocular housing should be opened, a cross ruler should be placed on the platform, and 10X dividing eyepieces should be inserted into the left and right barrels for observation. The position and angle of the binocular prisms should be corrected, and when the binocular eyepieces are rotated to different angles for observation, the position of the cross ruler should be at the same position in the field of view of the left and right eyepieces, and then fixed firmly.
When observing with a binocular microscope, sometimes there may be inconsistencies in brightness and color between the left and right fields of view, which can affect the observation. This is due to the damaged spectral film of the prism. In this case, the prism should be removed and sent to the microscope manufacturer for re coating before assembly and use.
What microscope is used for organizing cells
A. When observing a water sponge slide with a 10x objective lens, the distance between the slide and the objective lens is 0.5 cm. If observing with a 30x objective lens, the distance between the slide and the objective lens should be adjusted to around 1.5 cm
B. If there is a letter'd 'on the glass slide, the letter' p 'will appear in the field of view
C. When observing the guard cells in sunflower leaves, if the slide specimen is moved to the right, the guard cells in the field of view will move to the left
D. If you observe eye worms swimming to the upper right in your field of view, you should move the glass slide to the upper right for tracking purposes. We recommend using the following microscopes for our optical instruments: 1. TL2800A Research Biological Microscope, 2. XSP-2CA Student Biological Microscope, 3. TL3000A Research Biological Microscope, 4. TL1800A General Biological Microscope, 5. TL-800T Teaching Biological Microscope
