The designations for the Optivisor are as follows:
Each unit comes with one lens. Other interchangeable lenses are available.
In this table, Pwr = magnification power and FL = focal length.
. No . . Power. . FL
. .2 . . 1.50 . . 20"
. .3 . . 1.75 . . 14"
. .4 . . 2.00 . . 10"
. .5 . . 2.5
I'm an Optivisor user too since the 1980's. It's comfortable enough to cause
a fellow a lot of embarrassment.
Back then I spent a period of time repairing land mobile radios for a
company in Oakland, CA. The Optivisor was boon for swapping out SMDs,
especially on tiny hand-held radio pc boards.
I put my entire stuffed K2/100 together with the same lamp.
No problems and I don't hear any noise from the lamp in said K2.
I had to get used to soldering through the magnifier but that's only
because I'd never done it before. No big deal.

I've been using a 5 diopter Optivisor ever since I started SMT work at
the turn of the century .. plus a halogen desk lamp and a good pair of
tweezers :)

While a good bright light (however that is come by) is important, I don't find
the magnifiers on these swing arm lamps terribly useful for fine work. The
problem is that viewing angle can be critical and putting the glass in the
sweet spot is fidgety.
A head worn magnifier is far better in my

I have a Luxo lamp mounted on a tensor arm and with a 6" dia circline

It was made in USA. Two (very negative) comments:
