4.1 C-Mount Back-Focus Adjustment
The back-focus of the ATOM one SSM500 is adjustable. This helps to adapt
to any lens to have a perfect focus.
The following diagram is showing the components of the lens mount, from left
to right those are:
•Sensor mount
•Lens mount
•Lock ring
For adjustment do the following procedure:
1. Attach your target lens to the ATOM one SSM500. Try to tighten
it a little.
2. Loosen the lock ring to release the lens mount.
3. Turn the lens mount with your lens for back-focus adjustment.
4. Check your focus on a monitor. Focus assistant is helpful.
5. Carefully tighten the lock ring, since this will change back focus a little.
6. Check focus again. You may repeat steps 3-6 until you are satisfied.
7. Finally, firmly tighten the lock ring with your hand (do not use tools!).
Be carefully and sensitive with the locking threads. In rough environments
you may secure the lock ring with lock-tight.

4.2 B4 Back-Focus Adjustment
The back-focus of the ATOM one SSM500 is adjustable. This helps to adapt
to any lens to have a perfect focus.
The following diagram is showing the optical converter, what can be removed
for adjustment.
For adjustment do the following procedure:
1. Remove the optical converter by unscrewing the 5 front screws.
2. Behind the converter, you can place shims to compensate back
focus settings.
3. Add or remove shims on demand. The shims will fit only in at one
orientation. Refer to the index bolts for rotation and the laser
engraving for orientation.
4. Reassemble the optical converter with the 5 screws.
5. Attach you B4 lens and check again the back focus.
6. Repeat until back focus is correct.
7. Note the used shims used for a specific lens for faster changes
later.
The provided shim set does have a lasered thickness marking to simplify the
process of setting back focus. It is highly recommended to check and adjust
back focus on B4 lenses, especially when you swap between brands.
Power On/Off
16
5Power On/Off
After connecting the power cable, the camera will turn on automatically and
the Sys LED begins to blink green. The boot process takes about 20 seconds
and is being visualized in the OLED display. During boot the fan will spin at
maximum speed.
If the camera has been turned on and the power is interrupted, the camera will
turn on again automatically once power is supplied again.
To power down the camera press the power button for ~3 seconds or use
the shutdown command. During power down the fan will spin at maximum
speed. The camera will then enter standby mode.
In standby mode the Sys LED glows yellow. To turn the camera on again, press
the power button for ~3 seconds, or cut the power for at least 5 seconds
before reconnecting it.
Note: It is recommended to shut down the camera with the power button or
shutdown command at the end of a production to ensure no corrupt image
data is stored.

The OLED display will show the following screens, each screen is shown for 3
seconds before switching to the next screen:
•Main Screen: Shows the operational mode (“TRIG” for the Trigger
Mode and “SSM” for the SSM Mode), the firmware version and the IP
address.
•Genlock Screen: Shows the Genlock status. See chapter 10.6 for
details.
•Record Screen: Only displayed if a recording is running, shows the
buffer which is currently used for recording (Trigger Mode only).
•Playback Screen: Only displayed if playback is running, shows the
buffer which is currently used for playback (Trigger Mode only).
•Phases Screen: Shows the number of active phases (SSM Mode only).
Operation modes
19
7Operation modes
The ATOM one SSM500 supports two operation modes:
•Trigger Mode: This mode uses the internal storage space to record
and playback slow motion video with up to 500 frames per second.
This version can be used stand alone.
•SSM Mode (Super Slow Motion 4x): This mode does not use the
internal storage but streams with 240 FPS via four HD SDI (4x
1080p60) outputs This version is intended to be used with external
storage / video server solutions (like EVS).
The operation mode can be switched by the user with the switch_mode
command. To trigger this command from the ProVideo GUI go to the Info tab
and click on the “Switch to Trigger Mode”or “Switch to SSM Mode”button
and wait until the device has rebooted.
The following chapters give an overview on the functionality of the camera, for
further details, please refer to the Reference Manual.
7.1 Trigger Mode
In this variant the ATOM one SSM500 works as a stand alone camera with
internal recording.
It can record up to 500 frames per second with a memory depth of 30.000
frames. This will give you a recording time of 1 minute at 500 FPS. By lowering
the frame rate the recording time can be extended accordingly.
It is possible to split the 30.000 frames in up to 4 smaller buffers on demand.
The recording frame rate is independent of the video output format.
The slow motion ratio is defined by:
Slow Motion Ratio = Recording Frame Rate / Output Frame Rate
Examples:
Record 500 FPS / 1080p50 = 10x
Operation modes
20
Record 500 FPS / 1080p25 = 20x
In addition to that, the playback speed can be slowed down to further increase
the ratio.
In trigger mode the camera has 2 independent output channels:
•Live
oAlways shows the live stream
oThe live frame rate is independent of the recording frame rate
oIs shown on SDI outputs 1 & 2
•Playback
oCan show the recorded slow motion video.
oThe slow motion factor is recording FPS / play back FPS
oOptional it can show the live image if no playback is running
(auto live)
oIs shown on SDI outputs 3 & 4
SDI 5 is always showing a live image. This can be used by the camera
operator as a local monitor.
Both output groups have independent image processing pipelines for best
flexibility for color grading and post processing.
Refer to chapter 7.1.2 for workflows details.
7.1.1 Production Preparation
For any production the camera needs some settings to meet the project
requirements.
The following order is recommended:
1. Define lens system / lens control (motors, RCP, etc.)
2. Select the video output format, e.g. 1080i50
3. Select the recording frame rate / slow motion ratio, e.g. 300 FPS = 6x
4. Select number of buffers e.g. 3 x 10.000 fames (~33 seconds @ 300
FPS per buffer)
