For the kind of SMT work that most of us are doing, a head-mounted
magnifier is far better than any fixed microscope.
The problem with fixed microscopes is that they also fix YOU and the
object you're looking at. The bulk of the microscope also blocks your
normal direct view of the workbench,

A little bit different but you can get good magnification by mounting a
webcam above the work piece and viewing it on a screen.
Many old VHS cameras have superb zoom optics which are ideal for this
kind of 'head up display'. I tried it once with the camera mounted a few
feet

Do you really mean a 5 power lens? The ones I see listed only go to

I have to add a second or a third to Don's comment here. I've had several
Optivisor's over the years and got my first through Heathkit back in the day
when they were all the rage. The one I still have left has no scratches on the

Some Optivisors have a simple friction grip headband adjustment that I found
has the same problem. The good ones (IMHO) have a knob on back for setting

Hi all,
I'm looking for recommendations for one of those binocular, head mounted,
magnifiers to improve my SMT work. The parts are TINY compared to my old HW-16
and HA-14!
Thanks,

Hi all
Bob,
Do not scrimp on this particular item. Yes, there are less expensive
alternatives than Optivisor, but some have plastic lenses that are not

I have one that has a working length of about 10 inches (OK for
soldering without
I've been using the cheap head magnifiers (typically $5-7) for years and
am pretty happy with them. If you go to mcmelectronics.com and type in
magnifier in the search box, you'll find a range of quality and prices.
The one I use is the $6.99 one. I remove the 2 lights and battery
holders to

There are pretty cheap ones that work perfectly for SMT. I got one new on
ebay for about 80 bucks and it is fabulous. 10x (or less)
