View Full Version : Any optics people out there?

12-08-2014, 09:29 PM
I just picked up a microscope for the shop, fixed power. Head is 2x, and it has a pair each of 10x and 20x eyepieces. Too powerful for most of the simple chores I had in mind, so I'm thinking 2x eyepieces would be just the ticket. I have found 5x eyepieces for sale; so 10x would be better but still a little strong. I haven't found anything yet less than 5x, so I'm not sure they make 'em.

On to the $64,000 question. Could I buy a couple 2x jeweler's loupes and snitch the lenses out of those and make it work? Any way to figure out the focal length before I start making chips? I may just go ahead and try it, but I thought I'd give ya'll a shout first for opinions. I am clueless, so I'd appreciate your help.

Why not just change to a lower objective lens, like a 10X, objective times the eyepiece give the magnification, eg 10X objective times 5X eyepiece gives 50times magnification.
You can get graticuled eyepiece sets for measuring with it too

Unscrew the eyepiece and hold a loupe in its place and see if you can get it to focus with the loupe at the distance it would be in an eyepiece? Iv seen those loupes on sale for $10 for a pack of 5 different magnifications and they are useful around the shop (Can't tell if your carbide is chipped without em!), so what do you have to lose by testing it out?

No, It will not work, probably.

I dont think I have seen anything less than 5x eyepieces. Best bet is to buy a 1x objective.

Can you use loupes? Sure you can. But they will not be well corrected for this use so the quality of the image may/WILL suffer. How much will it suffer? Impossible to tell without trying it.

Yes, get lower power objective lenses. Check out Anchor Optics:
