Positive phase contrast (differential) biological microscope ZXS-770C
A contrast microscope can be used to observe unstained specimens
Product details
Phase contrast（poor）A microscope can be used to observe unstained specimens. Living cells and unstained biological specimens, due to the different refractive indices and thicknesses of the subtle structures in various parts of the cells, do not change in wavelength and amplitude when light waves pass through, only in phase (amplitude difference), which cannot be observed by the human eye. The phase contrast microscope changes this phase difference and uses the diffraction and interference phenomena of light to transform the phase difference into amplitude difference to observe live cells and unstained specimens. The difference between a phase contrast microscope and a regular microscope is that it uses a circular aperture instead of a variable aperture, an objective lens with a phase plate instead of a regular objective lens, and a telescope for axis alignment.
phaseLining（poor）Advantages of microscope: equipped with phase contrast objective lens, rotary disc condenser with circular aperture, coaxial telescope, and green filter. The function of a green filter is to narrow down the wavelength range of illumination light and reduce phase changes caused by different wavelengths of illumination light.
phaseLining (poor)Microscope has a widely used image output system. The computer type phase contrast microscope is equipped with a CMOS imaging system for microscopes, which can be used to connect to a computer. We also offer digital phase contrast microscopes that can be equipped with digital cameras and DSLR cameras. You can directly operate a digital camera or DSLR camera to take photos and save image data.
