Hi Thomas,

A high resolution target for what exactly? Calibration in um? Or perhaps
phase contrast resolution?

Try
http://www.graticules.com
in any case.

NPL certification of the um scale is nice but if you aren't working to GLP
or ISO9001 it's not absolutely necessary. Depends on what you call cheap. I
did miss a '1mm scale divided by 100' Graticules calibration slide on eBay
last week that went for £21. Otherwise expect to pay over £200.



Also look at the following links from our website:

Finder'

Invitrogen produce high quality triple labeled fluorescent stained BPAE
cells and kidney sections on glass slides to ensure the microscope is
working well [confocal or fluorescence, but not brightfield].

Hi
Does anyone know a good (cheap) place to get a positive high resolution
target for a bright field microscope (50X, N.A. 0.55). Inside the EU would
be best.
Thanks
Thomas
