Hello to all, I thank you in advance for any help you are able to give me. I use
stereo microscopes to inspect and work on laptop motherboards. I recently
purchased this microscope from eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&_trksid=p4340.l2557&rt=nc&nma=true\&item=200604710291&si=%252Bg5HRAfHnveryGdMyUgeCscTrXQ%253D&viewitem=&sspagename=\
STRK%3AMEWNX%3AIT
This came with 15x WF lenses and a coarse adjustment from 1 - 6. It has a camera
and "internal" light source attachments from the factory. I purchased this to
replace my Bausch & Lomb Stereo Zoom 4. The B & L has 10x WF lenses. The view on
the AO 580 is very dim at best, but clear, under the same lighting as the B & L,
through out all coarse ranges.
What is not advertised in the eBay listing is that this has an internal
"turret" of 5 filters for the incorporated illumination, one of the filters
being red. Changing filters has no effect when using an external light source.
To date I have not used nor purchased the light source for the internal
illumination. I have only used an external light source. Again the view is very
dim.
I have inquired to several places selling similar, if not the same microscope.
They all say the one they are selling works fine with only an external light
source. What am I missing, if anything? What could be wrong with this? Is it
worth having or fixing? Is it possibly a specialized microscope that is meant to
have a dim view for some reason?
Please forgive my lack of proper technical wording insofar as microscopes go.
Again I thank you for any help or advice you are able to give.
