DESCRIPTION AND USE
The instruments in the CHART PROJECTOR family are designed for projection of optotypes on a wall-
mounted projection screen. Operation of the instrument is analogous to that of traditional chart pro-
jectors. The instruments can project high-quality optotypes, created using sophisticate DIADUR
technology, for use by the ophthalmologist or optician, each within the limits of his competence, in
making measurements and clinical evaluations of visual acuity and point up limitations and defects in
vision.
This type of instrument permits projecting up to 47 different tests (according to model) including ste-
reoscopic testing, tests for heterophoria and astigmatism, red-green tests, and polarized tests, in addi-
tion to letters, numbers, directional Es, figures for children, and Landolt rings.
The instruments are designed to be used only in spaces for medical use (in particular, spaces suitable
for use of Type “B” devices with applied parts); for example, in ophthalmology clinics or in optician’s
or optometry.
laboratories and/or centers. The electrical system powering the instrument must comply with the rele-
vant laws and regulations in force in the country of use.
AMBIENT CONDITIONS FOR SHIPPING,
STORAGE, AND OPERATION
