I recently learned there are different types of phase, namely dark/positive vs. bright/negative. After reading around, seems like what we typically know as simply "phase" is dark phase, but I was curious if anyone had some more examples of the difference between the two types? I found a diatom example here but glassy refractile things tend to confuse me... ;-)
This surfaced when a [molecular biology/bioinformatics] lab obtained a darkfield condenser because they thought it was for 'dark phase' and the rep apparently was useless.
Thanks!
