COMPONENTS
Scan position adjustment range (blue)
Displays the "Scan width × Scan width" range at the focal point on fundus.
In the "Scan width × Scan width" range, it is easy to obtain the sufficient output sensitivity for tomo-
grams.
Scan possible range (red)
Displayed only for "5 Line Cross" and "Radial" scan patterns. This range shows the "12.0mm×
12.0mm" range at the focal point on fundus. This is the limit range where you can get a tomogram
by using this instrument. If a tomogram exceeds the range indicated by the blue line, you cannot
always get the sufficient output sensitivity because the pupil and others obstruct the photography.
Fine adjustment buttons (up/down/right/left)
Each time you touch these buttons, the scan position is moved by about 0.03mm (on fundus) in
the arrow direction.
Rotation buttons (clockwise/counterclockwise)
Displayed only for "Line" and "5 Line Cross" scans. Each time you touch these buttons, the scan
line is rotated by 1° in the arrow direction.
RESET button
Press this button. The changes for the position, which were performed by the fine adjustment but-
tons and rotation buttons, are reset. The initial position is set again.
