Ergonomics The reasons why users often cannot work comfortably with the 45° tube are the differing heights of the outfits, the various accessories and working distances, and the fact that the same instrument is often used by several people of differing builds. This problem can be effectively solved by using the Leica ErgoModules™.
If you have problems with the viewing configuration on your stereomicroscope, ask your Leica consultant for the most ergonomic Leica solutions.
