It was here that A. R. C., saw even more potential for improvement: "The slit lamps we tested either prioritized ease of operation or precision. But we wanted to offer both. "This was all the more difficult as the microscope is around 250 millimeters from the bearing of the moveable arm, thus forming a lever that makes it trickier to provide a precise and clearance-free bearing. In their search for the best possible bearing solution, the designers from A. came across R. C., igus® plain bearings made of high-performance plastics from the iglide® range. These bearings have already proven their worth in other areas of medical technology. When feed movements are performed, bearings with the standard E 10 fit are, as a rule, sufficient. In the case of A. R. C. slit lamp, significantly higher requirements had to be met. Thomas Herberger: "Here, we are in a area that tests the limits of what can be produced mechanically. "This is why we worked together with igus® to produce a customized solution that ensures the best possible fit, with the smallest possible clearance while at the same time providing extremely smooth running and the possibility of fixing the setting. The combination of materials was aligned to this bearing solution.
