Yes, I know, it's for metallurgy! But how do the optical properties of
these objectives differ from normal brightfield ones? How might they
be expected to perform for biological applications, for example?
Pete's right, mostly the difference is that met objectives don't use
cover glasses. However no one uses tube length any more. Now every
thing is infinity corrected. Another big difference is now all met
microscopes have standardized magnifications at 5, 10, 20, 50 and 100
times.
The quick answer is usually met objectives won't work for biologically
prepared specimens.
Thanks,
