1
Q
How is contrast created?
A
Crystals with lattice planes cause homogenous deflection. Can then put in aperture in place to focus on a particular area.
2
Q
What is bright field microscopy?
A
When the aperture focuses on un-deflected rays
3
Q
What is dark field microscopy?
A
When the aperture focuses on deflected rays
4
