The glass parts used in constructing the sample cell were cleaned by sonication at 50-60°C for 15-30 min in a solution of Pex (Peck's Products Co.) and distilled water (three times in fresh solutions), followed by distilled water (three times), acetone (one time), methanol (three times), distilled water (three times), and finally deionized water (two times).

In previous work where we used a phase contrast microscope [R. V. Durand and C. Franck, Phys. Rev. E 56, 1998 (1997)], the depth of field was approximately 10 μm, compared to 2-3 μm for the present work.

note
-
The background intensity at a given point was estimated by averaging the intensities of the pixels within a circle of radius equal to the CG background subtraction length scale. This local background intensity was subtracted from the original image.

note
-
If a given pixel has the brightest intensity in a circular region around that pixel, then the pixel is called a candidate particle. By looking in more detail at the intensity profile around each candidate particle, spurious particle identifications can be eliminated. The CG candidate particle length scale is the radius of the circular region used to determine the candidate particles.

The intensity weighted zeroth, first, and second position moments were calculated for the intensity profile of each particle using a circular region. The radius of this region is the CG moment calculation length scale.

The brightness (zeroth moment) is the sum of pixel intensities of the particle over a circular region equal to the CG moment calculation length scale.

Ironically, however, having h=0 would be too much of a good thing, because in that case, no particles would be seen, and thus no RDF could be computed. So a finite depth of field is always needed in colloidal microscopy.
