Auto Refractometer LMAR-402 is an ophthalmic instrument that measures refractive error more quickly and accurately. Minimum measurement range is different for each shape like for Sphere-20 to+20D (VD=12) 0.12D/0.25D step, Cylinder: -8 to+8D 0.12D/0.25D step. The angle of the Axis can range from 0 to 180 ° step: 1 ° and with Ø2.0mm of the pupil’s size. It has a different color LCD screen as well as an operational menu.
