There is no apparent connection between van Leeuwenhoek who developed his simple (single lens) microscope system and the work of Zacharias Janssen is associated with the compound (two lens) microscope invented in 1590. Van Leeuwenhoek was unable to use the compound microscope because magnification was too low. The microscopes built by van Leeuwenhoek (around 1670) had ten times the magnification of the compound microscopes of the day. One could say that Janssen helped van Leeuwenhoek succeed by getting everyone else to use the inferior microscope.
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 main disadvantage of the Leeuwenhoek microscope was that it only had one lens. On the other hand, it had much better magnification and clarity than the compound microscopes that were being used at that time. The inventor was Antony Van Leeuwenhoek.

The scanning electron microscope has a magnification range from 15x to 200,000x (reached in 25 steps) and a resolution of 5 nanometers.
The Dissecting Light Microscope range of magnification is 20x to 80x. The Compound Light Microscope ranges from 40x to 1000x -40x Scanning -100x Low Power -400x High Power -1000x Oil Immersion
Leeuwenhoek made microscopes that were simple and tiny, but he ground lenses so precisely that the magnification was 10 times that of Hooke's instruments.
To determine the magnification of the eyepiece on a microscope take the total magnification for the microscope and divide it by the total magnification of the objective lens. The answer is what the magnification is for the eyepiece.
One that has a magnification range of 20x-100x.
Anton Von Leeuwenhoek
it would be 15 times 40 which is 600 times magnification
One can calculate the total magnification of a microscope by multiplying the magnification of the eye piece by the magnification of the main scope. For a compound microscope one must multiply each eye piece magnification.
Antony Leeuwenhoek's job prior to working on the microscope was being a shopkeeper.
