====================================================
Dear Colleagues,
We are looking for a computer-controlled device that is able to project
acuity signs (e.g. Landolt rings, letters, ...) onto a rectangle screen
that
covers a range of about +/- 30 degrees in horizontal direction with
variable distance and magnification. The device should be able to test
a visual acuity of 32/20 for a distance of 5-6 meters and a visual acuity
of 20/20 for 40 centimeters.
Is anybody aware of such a device or knows whom to contact ?
Thanks in advance !
