11-2-4 READOUT TIME OF THE HORIZONTAL LINE
Readout time and exposure time can be varied with Lightsheet Readout Mode for synchronizing the
camera readout with the illumination scan.
Vn = Number of vertical lines
1H = 7.2 µs to 237.6 µs
Readout time = (Vn / 2 + 5) × 1H
Available setting range of the exposure time is the following.
Vn = Number of vertical line
1H = 7.2 µs to 237.6 µs
Setting range 1H to Vn / 2 × 1H
