11-1-5 CONFIGURING EXPOSURE TIME
The exposure time setting can be done by the units of seconds.
The actual exposure time setting is defined by the following formula, and the camera automatically
calculates a longer and closest value from the specified exposure time setting.
(1) Standard scan
Exp1 = 7.2 µs to 1800 s (input in units of seconds)
1H = 7.2 µs
Exp2 = ROUNDUP (Exp1 / 1H) * Round up to integer
Calculation formula
Exp2 × 1H
(2) Ultra quiet scan
Exp1 = 172.8 µs to 1800 s (input in units of seconds)
1H = 172.8 µs
Exp2 = ROUNDUP (Exp1 / 1H) * Round up to integer
Calculation formula
Exp2 × 1H
Available setting range of the exposure time is the following.
Scan speed
Setting range
Standard scan
7.2 µs to 1800 s
Ultra quiet scan
172.8 µs to 1800 s
Note
•
Ultra quiet mode is used for the Photon number resolving mode.
