1. Function Introduction
1. Uses
PM 200 is a digital precision optical instrument used to measure stance between
human pupils in the process of optometry for fitting ectacles.
2. Characteristics
This device is designed in a scientific and reasonable way, integrating technologies
on optics, mechanism, electricity and microcomputer into whole.
• Using an optical method to realize hairspring orientation which places the
mechanical orientation
• Adopting a full-digital design to effectively eliminate error optometrist’s artificial
measurement, thus allowing objective and precise measurement of patient’s
pupuillary distance
• Save energy for low power design
• A flexible baffle design convenient for storage which avoids possible
embarrassment in operation.
