You are asking about a reflected light or EPI scope.
Look for Zeiss EPI Plan, Vickers and Richart for scope for that
kind of work. If the work varies much in size a Zeiss WT or
Universal will be the best bet. Leitz also makes EPI scopes but
IMO Zeiss has the most varied and versatile equipment for that
kind of work.

is the way what say you want works.

I have something like
this:http://www.corelresearch.com/Zeiss_Z-4107IN_1.jpg
and http://www.arsmachina.com/leitz_ortholux.htm
To get a good scope that has a guarantee and is serviced and
ready to go. Expect to spend $1,500 to $7,000 for a good Zeiss
WT on the low end and a universal or a fully decked out for
transmitted and reflected light Zeiss Universal or Leitz scope.
Richart and Vickers are probably a better bargains but Zeiss and
Leitz have the best supply of parts and I believe Zeiss is more
versatile for EPI work.
If you are on a strict budget and willing to roll the dice on
ebay while I can't find an example right now a Leitz Orhtolux
with a Metalux EPI head can go for as low as $600 and Vickers,
Reichart and other good quality scopes can go for as low as 300
to 400 bucks.
If an inverted scope will work for you Unitron comes in the game
and while not the quality of Zeiss, Leitz, et. al. often a
complete one with polarized light will sell for about $500.
Here is a Japanese copy of a Unitron models that is a rare
configuration
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=7321&item=3878873110&rd=1&ssPageName=WDVW
I have one it works but the images are poor beside the images
from beat up dirty Zeiss EPI plan just as it came from the box
from ebay with out cleaning or positioning the light.
You don't say were you are. I know were there are a number or
scopes that could be built to meet your requirements and if you
are in the right place the sellers can help you get started as well.
I am not a salesman or receive anything but good will for the
deals I put together. I am retired and money not only is
stressful but makes it impossible to be objective. I may not be
right but it will be a mistake not something that I
intentionally did to make a buck on.
If I can help my phone number and email are somewhere on
www.couger.com/gcouger
Feel free to call or email me but keep the call between 3pm and
3AM CST. There rest of the time I take no responsibility for
grouchy troll that answers he phone. Before that troll gets
enough coffee to wake up he may not remember the conversation
and have any idea what he is saying.
I think you need to describe what you need to use the scope for.
As you see you are going to part with a considerable sum of
money but the up side if you don't buy new scopes you can expect
to get 75% to 110% or more back when you sell it if you do
your job shopping.
