Principles of a phase microscope
There is a hook-like slit between the condenser lens and the lighting, and a phase plate is located inside the object lens.
When light is emitted from the lighting of the phase microscope, the light which passes through the hook-like slit doesn’t change the direction of the light which passes through the part of the object (sample) with the same refractive index.
When the light passes through the phase plate, it delays the phase by π/2 or 3π/2.
Meanwhile, the light which passes through the part with a different refractive index changes its direction due to a diffraction phenomenon. Thus, the light passes through a part other than the hook-like slit without delaying the phase.
These two lights meet at the location of the object’s image, and due to the interference, there is a phase-difference which changes into a difference of brightness proportional to the phase-difference. Such difference is enlarged and observed by the ocular.
HOW TO USE
① Place the sample to be observed on the stage and fix it.
② After connecting power to the illuminant device, turn on the light and adjust to an appropriate intensity.
③ Place the eye on the ocular and move the focus handle up and down to focus the sample clearly.
④ In case of general stages, move the stages with the hand to set the location of the sample’s image.
In case of mechanical stages, move the double-layer to the front, back, left and right.
⑤ When observing, turn the object lens clockwise from low magnification to high magnification.
⑥ Using the eye-gap adjuster or diopter, precisely focus the image to fit the user.
During observation under high magnification [Object X100]
When observing with 100x oil lens, apply a single drop of emulsion oil on the preparation (sample),
and observe while properly adjusting the precision handle.
When observation is complete, wipe off the emulsion oil on the tip of the object lens.
Do not touch with the hand, and wipe off carefully using a clean sheet of cloth.
To maximize the effect, use the aperture or light-amount adjustment switch to adjust the amount of light.
