Want a good quality pocket magnifier .

I'm looking for a good quality magnifier, one i can keep in my pocket
or key chain. My instructor uses a Bausch and Lomb Hastings{triplet}
20x but the lens is too small for me. Is there one with a slightly
bigger lens of the same quality small enough to keep in my pocket? It
will be used for id of weeds, pests,etc. Thanks.

Such questions are not easy to answer, as many factors are involved
(personal habits, size of hands, size of pockets in typical garment, etc).
Personally I find a good field of view most important, which means a wide
diameter lens. I have always been happy with a basic (and cheap) 8x lens,
and went through several of these before they went out of production. When I
needed a replacement, last year, I went to my optician who sold eschenbach
hand lenses. After a quick comparison of all the magnifications in stock I
had no hesitation in buying the 8x lens, this offered much more viewing
field than the next higher magnification (I forgot what it cost, although I
do remember it was not cheap). I have a wide diameter 15x lens here
somewhere, but I cannot say I am using it much.

I suggest you go to a shop with a good selection of lenses and make a direct
comparison (it is a good idea to bring an object to look at, with lots of
interesting detail). Then watch for the amount of distortion towards the
edges of the lens.

A quick google turns up http://www.kooters.com/sezlens.html (it is linked to
a webstore) which offers useful comments.

Hope this helps,

Want a good quality pocket magnifier .

I had a nice old Hastings Triplet 10x and the B&L 20x on a lanyard and lost
them last spring in the Smokies, so I had to replace them. I like having
both magnifications but found the tiny size of the B&L made it very
difficult to use for most people. I met a myxo specialist last month in the
Smokies who had the most amazing 20x hand lens and I just had to have it,
regardless of cost. Here's the info:

Iwamoto achromatic 20x, 16mm lens diameter, with a focal length of 10mm.
Chrome plated housing, with a leather carrying case.

It's expensive at $87.60, but if you want superior optics and a wide field
that makes it easy to use--even for folks not used to them--this is THE hand
lens to get.

I also bough the Meiji 10x, 21mm lens diameter, with a focal length of 17
mm, metal frame with leather case. This one is pricey at $62.25, but is
extremely high quality and the optics are incredible.

I use them for botany and geology. The 20x was used by 10 different people
last Saturday on a botany/geology field trip and even those who don't use
hand lenses found the 20x usable. Of course I had to teach some how to use a
hand lens.
