Other than Plusoptix vision screening devices and Plusoptix pediatric autorefractors this instrument is not designed for children age 6 months and older. Test person’s head need to be fixed in a chin rest. PowerRef 3 can be located outside of the line of sight by using a hot mirror. This way visual tasks can be offered to a test person in the open field.

In order to ease a custom, research specific set-up, Plusoptix offers optional auxiliaries (chin rest, hot mirror apparatus, sliding rail with camera adapter, etc.).

Plusoptix offers complimentary training at its Nuremberg/Germany headquarters (airport code NUE). Scientists are welcome to schedule training at their convenience prior to or after taking their purchasing decision.

With the PowerRef II (Preliminary model), more than 200 scientific studies have been conducted. Click here, to have a look at those studies.
