INSTALLATION AND ALIGNMENT
following procedures:
1. If using a wall mount, it is best to locate a wall
2. The following distances are important in the
setup of a refracting room:
to the distance from the patient’s eye to the
screen.
the distance from the slide to screen.
LETTER HEIGHT (LH) The height of a 20/200
distance times the tangent of 50 minutes of arc
or .014545.
LH (inches or mm) = RD (inches or mm) x
.014545
For example, a refracting distance of 240 inch-
inches (240 inches x .014545 = 3.49 inches)
3. Determine the refracting distance by measur-
ing the distance from the patient to the screen.
