What you see is not what you get.
The paper:
Stayner, L., E. Kuempel, et al. (2008). “An epidemiological study of the role of chrysotile asbestos fibre dimensions in determining respiratory disease risk in exposed workers.” Occup Environ Med 65(9): 613-619.
gives an account of the fibre lengths by TEM (transmission electron microscopy) and PCM (phase contrast optical microscopy).
It has a nice picture showing the proportion of asbestos fibres by length and diameter.
Asbestos fibre size
The fibres NOT seen by PCM are in grey. The fibres and fibre bundles were from a South Carolina textile factory.
