thats kinda a weird thing to want tho. microscopes are like mobile phone games where you gotta buy all sorts of extras just to enjoy the main product. For example, even if you ignore the attacthments, you still gotta purchase all sorts of other stuff like antigens, assays, stains, catalysts, clinical disposal services, etc before you can even use it on a biological specimen. Inorganic chem should be slightly easier.
But This stuff will set you back tens of thousands per month. Especially the disposals. Also im pretty sure there is some govt law saying you gotta be an institution or corporation to buy a lot of those catalysts and assays for obvious reasons.
OP, i think you could just rent lab time at your local public univeristy if you really wanna get into it. Let the American tax payer finance your fun
