alternatives for a dissecting microscope
can a magnifying glass be used instead of a dissecting microscope?

Are you thinking of this classic style ?

Re: alternatives for a dissecting microscope
It should give adequate [possibly excessive, depending upon what you are dissecting] magnification ... but the working distance will be short, and one hand will be occupied holding it.shawn perez wrote: ↑Sun Jun 20, 2021 7:28 pmI'm thinking about this oneMichaelG. wrote: ↑Sun Jun 20, 2021 7:56 amAre you thinking of this classic style ?

If you are actually doing dissection, or manipulation, I would recommend a 'stand' ... preferably with hand-rests.

Re: alternatives for a dissecting microscope
Hi Shawn,
that is a fake product, no triplet, not 30x magnification. But there are quite nice 10x and 30x real triplet=three lens design for a similar amount of money:

Re: alternatives for a dissecting microscope
A good 10x or possibly 15x folding loupe is extremely useful in the field. I use a Belomo 10x, extremely good value Belarusian loupe.
I would never buy a 30x loupe. Even 20x is too much, IMHO. Dim, small field of view, razor thin focus depth. Works better if it has a built-in LED light, but even then it's not very user friendly.
But a hand loupe is not a replacement for a stereo microscope. But depending on what you want to do, a 10x or 15x might be useful to you.

Please forgive the slight digression, but I found this fascinating page whilst searching for suitable examples to show Shawn:

Re: alternatives for a dissecting microscope
I have watch repair glasses that led lights. Interchangable lenses go up to 20x or so. I use 2.5x lenses on it. Sometimes it's useful for teasing apart plants.

Nothing beats the ergonomics of a stereo microscope for the things it does best, even if you can get by with a hand loupe or a visor.

Yes I was wondering about the one hand occupied part too. okay ill check it out, thank youMichaelG. wrote: ↑Sun Jun 20, 2021 7:53 pmIt should give adequate [possibly excessive, depending upon what you are dissecting] magnification ... but the working distance will be short, and one hand will be occupied holding it.shawn perez wrote: ↑Sun Jun 20, 2021 7:28 pmI'm thinking about this oneMichaelG. wrote: ↑Sun Jun 20, 2021 7:56 amAre you thinking of this classic style ?

Oh okay thank you I'm just looking for options before I actually get one. Its true that its not a replacement for a stereo microscope. thank youviktor j nilsson wrote: ↑Sun Jun 20, 2021 8:05 pmA good 10x or possibly 15x folding loupe is extremely useful in the field.

Re: alternatives for a dissecting microscope
I also bought a large illuminated magnifyer on a standd. It was only about 3x, with a more powerful loop built into the glass. It was clumsy to use and just added clutter.

Re: alternatives for a dissecting microscope
I was using the stereo microscope (at 45X) for dissection. That gave me great precision but it was difficult to manipulate my tools when everything was magnified so much. I have since bought a digital microscope at roughly the same magnification. It allows me to take pictures to a memory card and to see my specimen on a screen instead of looking through lenses. I don't use it for dissection though--I do that pretty much by naked eye.

Re: alternatives for a dissecting microscope
Typically for tasks done under the stereo scope people use a 0.5x auxiliary lens to increase working distance and depth of field while putting mag into a more useful range. You might find one allows you to streamline the whole process, and they are not that expensive for the generic chinese stereos.

That is exactly what is happening to me, manipulating tools is difficult hence I was thinking of alternative suggestionsDonSchaeffer wrote: ↑Fri Jun 25, 2021 11:14 pmI was using the stereo microscope (at 45X) for dissection.
