LM240 Lensmeter Internal Reading:
This device is suitable for spectacle measurement, spectacle
processing factories, spectacle retail stores, departments of
ophthalmology in hospitals and optical element factories to
measure diopter of spherical and cylindric lens, astigmatism
axis of cylindric lens, diopter of prism and of contact lens.


  Eyepiece system
