Description of the device
The CP-50 chart projector has a total of 37 test fields to determine the visual acuities of the
human eye. The individual charts are very clearly reproduced thanks to the special design of
the optotypes and the high resolution lens system. All tests are conveniently controlled using
the infrared remote control, with a switching speed of 0.03 seconds. The individual visual
acuities can be represented selectively using masks. The projector enables you to program
two separate test series.
The projector has 5 sets of charts:
Landolt rings in acuity levels 0.125 to 2.0
Numbers in acuity levels 0.1 to 1.25
Illiterate Es
in acuity levels 0.16 to 1.6
Letters in acuity levels 0.05 to 1.6
Illustration for children in acuity levels 0.2 to 1.0
