For all microscopes without C-Mount thread, especially for older instruments with norm tubes with an outer diameter of ca. 25 mm. All LM digital adapters with tubus husk include a tubus husk with a standard inner diameter of 23,20 mm.
Some microscopes´ tubes vary from the standard diameter of 23,20 mm. In this case the adapter does not fit tightly in the tube. The camera´s asymetrical weight makes the camera´s body rotate downwards, which makes it difficult to take landscape format photos.
To compensate this mechanical tolerance of the microscope, we now offer our tubus husk #TUSTA.  The #TUSTA is fixed with a knurled screw and an integrated brass ring which guarantees a stabile tight connection. Therefore we recommend  the #TUSTA especially for using with digital cameras on inclined tubes (minimum tubus length 15 mm).
