Hi What purposes people use scopes ? I mean people invest a lot money on them: Used goes: 250$-600$ (These sell as easy like honey in ebay.com) New ones goes: 1500$-6000$ What is the monetary gain to achieve with them ? What kind of income I can get by offering what kind of microscope services ? Or ...

Ok thanks. Seems microscopes are pretty much way over hyped.(watching too many science movies) I'll just stick to watching coins and rocks. Was hoping to use it for more exciting works. People just suggest watching pond "animals" or yeast growing which to me are very boring and pointless things to d...

Hello Where to buy a dust cover for microscope made from high quality material ? I don't like to put a cheap plastic pack or a cheap semitransparent PVC cover on it. So no for these.

Hello Zeiss eyepieces have the 5x as minimum magnification=lowest zoom available.(barrel size Ø23.2mm) ( 5x ,6.3x,10x,12.5x,16x,20x,25x,...) - Can I create my own eyepieces like for example 2x by removing lenses from existing Zeiss eyepieces ? - Lowest Zeiss objective lens is 3.2x so I could get 3.2...

Hello
When the first Zeiss infinity ∞ microscopes came to market ?
I have heard people say they are the best to get and ordinary light microscopes are worse than the infinity ones.

Basic light microscope is ok for looking large objects like 0.1mm - But I really aim for electron microscope quality 1e-6mm(1 nanometer). :D Everybody now talks about building nanorobots that enter humans.

Hello (rookie question)
From what value is the nX magnifcation calculated on lens ?
- If I have for example a 10x lens:
What is the comparison target ?
Where does the value come from ?
What does it really mean ?
Is it like 10x from a 1mm or from where it is calculated ?

What year was the guide made ? (These manuals never have any year stamp) - Zeiss handbooks=gebrauchleitungs are usually in Germany and it is very frustrating to translate them. + Zeiss' microscope manuals are so mediocre (Like Laboval 2: guide is like 20 pages describing only the minimum surface inf...

Hi 1.) How to center below light or how to know if it is already centered ? (I have Zeiss Laboval 2 DDR and it uses two "1.2mm" square slot keys(manual says="Vierkantaufsteckschlussel") to adjust somehow the lamp ?) 2.)
