Image Engineering iQ-Defocus
INTRODUCTION
Important information: Read the manual carefully before using this device. Inappropriate utilization may cause damage to the device, to the DUT (device under test), and/or other components of your setup. Keep these instructions in a safe place and pass them on to any future user.
Conformity
We, Image Engineering GmbH & Co. KG, hereby declare that the iQ-Defocus
corresponds to the essential requirements of the following EC directive:
- Electromagnetic Compatibility – 2014/30/EU
Intended use
iQ-Defocus is used to defocus the automatic focusing system of a camera with
high temporal accuracy. A typical use of iQ-Defocus is to measure the camera
release time in conjunction with the LED-Panel.
- Only suitable for indoor use.
Foreseeable misuse
Connect only to LED-Panel and DTS
iQ-Defocus can only be connected to LED-Panel and DTS. Usage with unsupported
devices will cause irreversible damage to the iQ-Defocus.
General safety information
Do not open the device without instructions from the Image Engineering support
team or when connected to a power supply.
GETTING STARTED
Scope of delivery
- iQ-Defocus
- 7.5 m extension cable for iQ-Trigger-T (6.3 mm TRS connector)
Commissioning
The iQ-Defocus comes ready to use. Follow the steps in chapter 3 to set up the measurement environment.
OPERATING INSTRUCTIONS HARDWARE
Setup
The setup of the iQ-Defocus depends on the measurement periphery.
Using iQ-Defocus on an iQ-Mobilemount
The iQ-Defocus is designed for seamless integration into the measurement
workflow with the iQ-Mobilemount.
To attach the iQ-Defocus to the iQ-Mobilemount:
- Remove the top cover of the iQ-Mobilemount (use a thin screwdriver as a lever)
- Make sure the tightening hand screw of the iQ-Defocus is loose
- Slide the iQ-Defocus into the grooves of the iQ-Mobilemount, as shown in Figure 1
- Place the cover back on the iQ-Mobilemount
Using iQ-Defocus on a third-party mount
The iQ-Defocus can be attached to a tripod using the ¼“ thread on the bottom of the device. We recommend using a boom stand when the iQ-Defocus is not mounted to the iQ-Mobilemount.
Adjusting for lens depth
The iQ-Defocus shutter blade can be easily adjusted for different lens depths. Apply pressure to the clip (A) and slide the shutter blade adjustment profile (B) to the desired position.
Using iQ-Defocus with other IE measurement devices
LED-Panel (timing measurement)
Mount iQ-Defocus in front of the device under test and connect the TRS connector (6.5 mm “jack plug”) to the LED-Panel (over an optional extension cable). Please refer to the LED-Panel manual for details on how to measure different timings (shutter lag, autofocus time, etc.) and how to interpret the captured images.
DTS (Dynamic Test Stand)
Mount iQ-Defocus on the device under test and connect the TRS connector (6.5 mm jack plug) to the DTS (over an optional extension cable). Please refer to the DTS manual for details on how to measure global flicker or modulated light mitigation probability.
Care instructions
- Always store the iQ-Defocus in the supplied case
- Avoid contact with water
- Do not use any chemical cleaning agents
- Use compressed air or a dust blower to remove dust
ADDITIONAL INFORMATION
Storage and transport
Ensure that the iQ-Defocus is fixed and the device is wrapped correctly for
transport to avoid damage to the shutter blade. Unplug all cables/devices from
iQ-Defocus before storage/transport.
Disposal instructions
After the service life of iQ-Defocus, it must be disposed of properly.
Electrical and electromechanical components are included in iQ-Defocus.
Observe your national regulations and ensure that third parties cannot use iQ-
Defocus after disposing of it.
Contact Image Engineering if assistance for disposal is required.
