the objective on a microscope causes the specimen to be inverted or fliped along the vertical and horozontail axis.

Carl Zeiss contributed to the first microscope by making the lenses better.

Van Leeuwenhoek made over 500 optical lenses (though they did not necessarily become 500 different microscopes) and can be said to have built at least 25 variations on his basic design of the microscope. Only nine microscopes, of the hundreds he built, remain. The best magnification of the lenses which still exist is 256 times. It is thought that he may have been able to produce magnifications of almost twice that.
Anton van Leeuwenhoek did not invent the microscope. The compound microscope was invented 40 years before Anton van Leeuwenhoek was born. The simple microscope was known 300 years earlier. Anton van Leeuwenhoek invented a method for making small spherical lenses that much increased the magnification of simple microscopes. The date is not know precisely, but around 1670, more than half a century after the discovery of the compound microscope, van Leeuwenhoek discovered a way to make small lenses of very high magnification that went significantly beyond the capability of existing microscopes. He advanced the design of the simple microscope. He used his inventions to make great discoveries into the world of microorganisms.
The lenses of a microscope form an enlarged image of a specimen.

Light microscope
a compound light microscope
primary lenses are that lenses which are maked by leunhoek .these lenses are used to see parts of different objects and these lenses had maked first.they are mostly used in ancient time. .
The microscope has two systems of lenses: the ocular lens into which the observer looks; and objective lenses placed directly above the object being observed.
compound light microscope (light passes through the specimen and produces a flat image)
The microscope.
The specimen prepared for a monocular microscope must be very thin so light can pass through it easily. The light then goes through a series of lenses that magnifies the specimen to appear bigger
because the specimen is always thin
The answer you are looking for is called a dissecting or stereo microscope. These provide a lower magnification range in comparison to compound microscopes and they use two sets of lenses, the eyepiece and the objective lenses. these then provide a 3D image.
A para-focal lens set is a set of lenses that when interchanged one for another will not require refocusing, the image of the specimen will remain in focus.
