[coccoliths] Microscope retailer UK

[Tom Dunkley-Jones]

Hi Christian,

GX transmitted scopes with LED are pretty good, especially the newer versions with slightly higher end specs. They are compatible with Olympus objectives, so we’ve just brought the GX bodies and added Olympus 100x oil lenses. A good solution for teaching / portable scopes at a reasonable price. Trinocular options and reasonable camera solutions also available with these.

all best
Tom

Hi Christian

I have not personally tried GX microscopes in any depth but it certainly is possible to get good microscopes for far less than the major manufacturers ask - the body should  be fine, the  main problem will be whether the optics are good. However, a lot of what you pay for with expensive optics are obtaining a wide and strain free field of view - ie no distortion at the edges. As a nannofossil worker these expensive characteristics are a bit of a luxury - what really matters is how sharp the nannofossil is in the centre of the field of view. I have an ancient Leitz Ortholux and whilst the overall field of view is nowhere near as good as on a modern Zeiss or Leitz microscope I can see individual nannos fine.

As for LED illumination this is absolutely the way to go, lighter, cheaper, more reliable and much easier to get a really bright illumination.

I suggest you try to get demonstration of the microscope before you buy and try it out with microscope sides you know well -

Hello all,

can anyone recommend a UK retailer for buying a 1st or 2nd hand nannoscope?

has anyone experience with GX microscopes (GT Vision)?

or ever worked with LED transmitted light?

Thanks,

Christian
