PS-Speck™ microsphere used to demonstrate a microscope point-spread function.
An orthogonal (x-z) display representing a microscope point-spread function. The microsphere used is a component of the PS-Speck™ Microscope Point Source Kit (Cat. no. P7220). This pseudocolored image was generated electronically from a series of microsphere images taken in x-y planes. The image was contributed by Jennifer Kramer, Scanalytics.
