Re: What makes a microscope collectible?

In my case the microscopes i collected were those I encountered along the way. I will admit to purchasing a couple that would have never crossed my day-to-day path, but were interesting in one way or another. I have a couple from the colleges I attended (I did not steal them) and the one I used at m...

Re: Collection disposal ?

Several years ago I gave the library two fairly good student microscopes (Swift M3200) with cases and they are still using them.

If they decide to accept my "collection" it will be for display only as some of the scopes are quite old and a little historically significant.

We will see...

Re: Improving a toy microscope..add a condenser?

I have quite a bunch of student microscopes that are like those being discussed here that are in varying states of restorability that I would be willing to trade to some enthusiastic person in the US for an authenticated bag of sand... remember, sand can be microscopic.

Re: Nikon Alphaphot YST Ph3 Slider

If you are handy you could make one from aluminum or brass or plastic or hardwood. You have all the critical dimensions so it will be easy-peasy. If you are using it for purposes other than the phase you have the freedom of some design creativity.

You might try screwing the small screw farther down into the slider. It's possible that it is a stop pin that works properly on the other side.

Re: Adjust Labophot lamp output? trim pot?

Possibly, the pot needs to be cleaned. I don't think there is a trim pot.

The LED kit is a very tidy retrofit and works very well.

If you remove the two thumbscrews the lens holder will come out (just don't let if fall) and you will be able to remove the bulb.

Re: Koolite substage illuminator - bulb replacement

This is a great candidate for an LED retrofit. With a little creativity you can build a very nice unit. With a 3W LED you will have as much illumination as you will ever need with that scope.
