HOW TO ADJUST THE PHASE-CONTRAST MICROSCOPE CONDENSER FOR PROPER VISION ALIENATION OF THE CONDENSER To make a good alienation of the optics of a phase-contrast microscope we have to follow the next steps. 1.- Turn on the microscope light and set it to maximum power. 2.- Raise the condenser to the maximum possible (Be careful! […]
Phase-contrast microscope Live cells can be clearly observed under a phase-contrast or interference phase-contrast microscope. The possibility that some cell components may be lost or distorted during sample preparation has not ceased to worry microscopy specialists. The only solution to this problem is to examine the cells while they are still alive, without any fixation […]
Unstained and therefore transparent preparations that do not absorb light are called «phase samples», as they slightly alter the light that passes through them. Usually, the phase-contrast delays 1/4 wavelength with respect to direct light and without deviation, which passes through a stained sample. Unfortunately, the eyes, like the sensors of the cameras, are not […]
Darkfield microscopy is a specialized illumination technique that benefit from the oblique lighting to improve contrast in samples that are difficult to see clear under normal lighting conditions in light field. All of us are very familiar with the appearance and visibility of the stars on a dark night, despite its enormous distances from the […]
