• Dioptr2


Dioptometers (also referred to as dioptre telescopes) are most often used to calibrate or measure the diopter adjustment of eyepieces found on telescopes, binoculars, cameras, microscopes, and endoscopes. Dioptometers can be adapted to other applications as well, and can even be used as a short focal length collimator by replacing the eyepiece with illumination. Dioptometers are available with different measurement ranges and magnifications, please view the catalog below for more info.
