magnifier

I have a Mantis on my workbench, which is great, but it's bolted down. Any suggestions for a good quality wearable magnifier? 4X seems about right for most work.

Along the San Andreas fault bolt-down is probably a good idea.

I have these in 5x and for some reason now they seem to only offer up to

3.5x (which would probably suffice):

5x works very well for SMT down to 0402. When I have to solder 0201 I leave my reading glasses on underneath it. Those are non-prescription, just 1.75x Dollar-store magnifiers. When having to read schematics plus solder 0402 and up I set it so I can peek above the rims of my reading glasses through the visor and only through my reading glasses to look at the scope or the schematic.

Dentists, dental hygienists and root canal specialists have really cool magnifiers but those are expensive.

I have the OptiVisor DA-5 version (2.5X) which I find adequate except for a few situations where I use them over my readers (+2.25 diopters), but then the depth of field is crap. ...Jim Thompson

I have the DA-5 too, but I think the DA-4 (2x) would be better since the working distance is 2" more (10")

Cheers

The image links on your web site went cold. Could have been this one but gone:

Yes but I need the magnification especially when working with sampling diodes the size of a salt grains.

When longer sessions are to be anticipated I place the DUT on a block of wood which reduces neck and spinal strain.

That'd be the one. Looks like I scrubbed in during one of my frenetic housecleaning modes ;-) ...Jim Thompson

I live in my optivisor at work*, mine has a flip down inspection magnifier on one side. (How else do you read the little pin numbers on connectors?)

Without a question, the best is the Carson Optical visor. I have one that has a series of perhaps six magnifiers.

Just wanted to add that I had an OptiVisor but when I tried the above I gave the OptiVisor away. The Carson unit has a larger field of view and is easier on the eyes.

Me too. A DA-5 with the OptiLOUPE Option.

Thank you,

Looks nice. I ordered one of these today

and if it's not good, I'll move up to the Carson.

This Amazon stuff is so cheap and easy to buy, you can order stuff and keep it or throw/give it away.

The OptiVisor is superb. It's the only visor I know that has prismatic correction built into the lenses, a feature that makes them much easier on the eyes.

(Prism lets you look with eyes diverged, relaxed, as if looking in the distance. Without prism you have to converge, yet, due to the magnifier, your eyes are focused for distance. That unexpected feedback confounds your eyes' normally cooperative vergence and focus mechanisms, the turn-in and turn-out extraocular eye-pointing muscles clash and strain, not knowing what to do, and you get eyestrain.)

The OptiVisor's lenses are glass, too, which means they last forever and never scratch.

Cheers, James Arthur

Definitely NOT wearable, but allows a lot of workspace in all dimensions as well as highly variable magnification AND capability for video capture.. Set up a Bessler enlarger with digital camera at the film plane. Ever see a (in-focus) 0402 fill your monitor screen?

I also have one of those but prefer the simpler visor and use a hand loupe in such cases.

That's the marketing idea: Build visors with integrated baseball caps. In the various team colors, of course. Plus a red one "Make America Great Again" ... 8-)
