LM digital SLR wide-field adapter: With focus settings and larger image field 

The new and optimized version of our popular LM adapter for eyepiece tubes with 30 mm inner diameter!

We improved and updated our LM digital tube adapter (see also LM digital C-mount adapter). The new LM digital universal wide-field adapter has a relay lens (corresponds to a field of view of a 10x eyepiece), an image field enlarged by 25% in comparison to our standard LM digital adapter and is focusable!

The LM digital wide-field adapter is focusable and has a sophisticated plan achromatic lens design. It uses the whole image field of the microscope - even the edges of the image are shown on the photo. Therefore we recommend using the LM wide-field adapter only with high-quality microscopes with fully corrected lenses (e.g. infinity corrected plan achromats, plan flourites, plan apochromats, etc.) With lower-quality microscope lenses (without the "plan" denotation) it is not possible to get the centre and the edges of the image in focus simultaneously since these lenses mostly show a pronounced focus field curvature. Looking through the eyepiece, however, the image appears in focus because the human eye is able to focus on objects at different distances. This process is called accommodation.
