Part 4

The mechanical construction for the lasers did not proceed very easily. After working for a full week on an extensive version with 6 lasers, the first test showed that it was unworkable. I could not get it low enough to the ground with the 4 tripods, and the construction was much too complex and awkward

So I had to find a more practical solution with everything on one stand, including the camera, the laser frame, flashes, etc. The initial version was 700mm wide, while the new version was only 300mm wide. At 700mm, the maneuverability was inadequate for small insects. Plus, the likelihood was too great that some unwanted objects would come between the laser and the detectors. To get more experience, I started with only 2 lasers this time. The lasers are now positioned on the very end so that the frame can be rotated all the way to the ground if necessary. Because now the camera is also resting on the frame, the balance is much better. Now the camera counterbalances the frame. Much work went into mounting the camera. My earlier arrangements were much too unstable. Now the camera is fastened at 2 points with an MB100 grip and the suspension of the 200mm macro-lens. There is no mechanical tension between the lens and the camera. it is quite safe. An extra plate was made for mounting under the frame. It uses a plate that fit directly on the tripod. If necessary, I can pick up and operate the whole setup in my hands. It weighs about 5 kilos in all. With the cable length to the module of about 2 meters, there is enough room to move freely. The entire unit can be seen in the picture.
