Eh, I'd spend the extra $200 and get a B&L unless you don't expect to use it much. At around $300, you would get a Stereozoom 3, heavy table and long arm. The Stereozoom dates back to the days they built magnetic RAM. It is designed for all day use. The working distance is kind of important if you expect to work on a PCB, since they are 3D.
But maybe the Chinese stuff would work for occasional use. However, the B&L can go in your will! ------Original Message------ From: Chris Albertson To: [email protected] To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] OT, looking for a good science forum Sent: Jan 26, 2013 1:36 PM On Sat, Jan 26, 2013 at 10:00 AM, <[email protected]> wrote: > If the intent is surface mount work, get an old B&L Stereozoom 3.

I'm looking to equip a biology lab. Need a compound microscope that has on the high side a 1000x magnification. Pretty much your "Standard" university lab microscope that all freshmen bio students would use. These are a little hard to know what's best to get But I think in addition I want a stereo microscope too. There are decent new ones from China for under $100 and older ones like you mentioned for about the same price. New ones are attractive because of advances like battery powered LED illumination. This kind of microscope is pretty easy to find compared to the other. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
