            This device is suitable for measurement detection departments, processing factories, sales departments of ophthalmology in hospitals and optical element factories, providing spectacular results. It assays spherical lenses' diopter, astigmatism axis of cylindric lenses, diopter of prisms and of contact lenses.     Features                                                                                                     1. Eyepiece system Equipped with a spiral focusing unit with a range of focusing of ±5D so as to suit various eye-sights.         2. Lens pressing unit With this unit, three plastic feet with springs are used to press lenses carefully without damaging the surface.       3. Lens pushing unit The unit is used to fix the lens position.       4. Printing unit Three identical point-making pens are connected in line.       5. Instrument's inclination regulating handle It allows the operator to regulate inclination of instrument so that he is able to work at a comfortable posture.       6. Prism compensator A prism compensator is useful when dealing with a prismatic lens from 5? prism diopter. There are 2 scale lines on the prism compensator. The upper lines of the prism shows the angle (from 0 to 180 degrees), and the lower line shows the prism diopter. Its range is 15 ~0~ 15.                                 MANUAL LENSMETER LM-500 (Without Prism) (EXTERNAL READING)           Specifications                                                                                                                                                                                                                                                                                                                                                                                                                                                                                Ranges of diopter measurement: +25D to -25D Minimum scale value: 0.125D at 0~±5D   0.25D at ±5D~±25D Astigmatism axis of cylindric lenses: 0~180° Minimum scale value: 5° Prism diopter of pattern A: At 1? interval in the range of 0~5?
