The PLM 528 Digital Pupilometer features the “cornea reflection light coincidence method”. This operates by aligning luminous points on the pupils with the measuring line. Results are displayed digitally in seconds. With the PLM-528 it is possible to measure PD of focusing point distances ranging from 30cm to infinite.
