'''Overview'''
Optical cross-talk is a concern with closely packed fibers. An air gap between fibers is an excellent way to minimize the possibility of optical cross-talk, but for the tagger microscope's 17 closely packed fiber bundles this is not an option. Therefore, the individual fibers are painted in the section that comes in contact with the other fibers.
'''Procedures'''
* Before painting the paint should be mixed with water to thin it out. It was found, through experimentation, that a 50/50 mixture by weight of white titanium dioxide paint and water yielded the best results as far as coverage and ease of use were concerned. If the paint is too think, it will clump up in the paint gun, if it is too thin, it will not cover the fiber well enough.
** Open the lid to the scale
** On top, place an open Tupperware container and tare it out.
** In to the plastic container squeeze 20 - 30 grams of paint.
** Add, using a pipette, an equal weight of clean tap water.
** Place a lid on to the container and shake vigorously until the paint and water are well mixed and smooth.
*** It was found that mixing/stirring the paint did not get rid of paint clumps, so shaking is the preferred method.
* Pour the paint in to the airbrush reservoir until it is about 3/4 full.
** The lid should seal any unused paint in the plastic container. When the airbrush runs out of paint, it can be replenished from this source.
