Here's a question I think very relevant to the topic title: isn't one fundamental difference between cylindrical lenses and prism pairs for doing knife edging the fact that with prisms you can stack the "tall" beams horizontally and have them expand equally while with cylindricals since the beam has to be in the exact center of the lens you have to expand these tall beams stacked vertically? With the latter I don't see how you could knife edge any of the multimode 500mW+ diodes without hitting the scanner mirror size limit with more than two diodes.
