The Dioptometer is a precision instrument used to accurately determine the diopter zero setting of another instrument.  The focusing sleeve of the dioptometer allows ± 1 diopter objective offset in ¼ diopter units.  The eyepiece allows ± 4 diopter accommodation to user’s eye.

The internal reticle defines the image plane at “zero” diopter position of objective sleeve when viewing a collimated image.  The Dioptometer eyepiece allows independent focus on the image plane, thus accommodating the user’s eye.  The Dioptometer, so set, provides a “zero” diopter standard with which to establish another instrument’s zero diopter alignment.  Errors in “zero” setting are easily checked using offset sleeve, graduated in ¼ diopter markings.
