 I am currently using an LM digital adapter with an old microscope.

My images are only focused in the centre, while at the edges they are flat and blurred (when I refocus, the edges become clear and the middle blurs).

Image blurring vignetting old microscope

All of our LM digital adapters have been developed primarily for use with modern microscopes (made after 1980) that are manufactured by top name brands. These microscopes have an “infinity optical system” which delivers corrected images even without an eyepiece. These optical systems consist of two parts: a lens and a compatible tube lens for correcting flaws in the image. This means that the image is error-free after the tube lens, i.e. before the eyepiece or the LM digital adapter.


Older microscopes still tend to have a finite optical system (170/160 mm tube length). These microscopes have lenses that exhibit serious flaws (image warping, spherical and chromatic aberrations, etc.) and this applies to all lenses, no matter how much they cost. These flaws can be resolved by using what is known as a compensating eyepiece (or compensating projective eyepiece). As every microscope manufacturer’s “finite lenses” exhibit different residual errors, unfortunately there is no single LM digital adapter that can improve or correct the various flaws of all the different makes. The only sensible solution is to use a microscope with an infinity optical system.
