10. Appendix
10.1. Precautions
Personnel not trained in dealing with similar electronic devices should not service this camera.
The camera contains components sensitive to electrostatic discharge. The handling of these
devices should follow the requirements of electrostatic sensitive components.
Do not attempt to disassemble this camera.
Do not expose this camera to rain or moisture.
Do not face this camera towards the sun, extreme bright light or light reflecting objects.
When this camera is not in use, put the supplied lens cap on the lens mount.
Handle this camera with the maximum care.
Operate this camera only from the type of power source indicated on the camera.
Power off the camera during any modification such as changes of jumper and switch setting.
10.2. Typical CCD Characteristics
The following effects may be observed on the video monitor screen. They do not indicate any
fault of the CCD camera, but do associate with typical CCD characteristics.
V. Smear
Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical
smear may be visible on the video monitor screen. This phenomenon is related to the
characteristics of the Interline Transfer System employed in the CCD.
V. Aliasing
When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on
the monitor may appear.
Blemishes
Some pixel defects can occur, but this does not have en effect on the practical operation.
Patterned Noise
When the CCD camera captures a dark object at high temperature or is used for long time
integration, fixed pattern noise (shown as white dots) may appear on the video monitor screen.
Disclaimer
Increased dark current (white spots) over time in ExView sensors.
It is known that radiation damage increases the dark current of a CCD sensor. This is also true
for radiation arising from natural sources, also known as background radiation. These sources
include:
1. Terrestrial radiation from naturally occurring radioactive isotopes in the soil.
2. Cosmic radiation originating in outer space.
3. Naturally occurring radioactive isotopes in the body.
The ExView series of CCD sensors have greatly improved responsivity, especially in the Near IR
part of the spectrum. This greatly improved performance comes at the price of accelerated
degradation (increased dark current) due to natural background radiation. This degradation
effect is approximately 4 times as fast as in standard sensors, such as Hyper HAD sensors.
The degradation effect will manifest itself as in increasing non-uniformity of pixels when viewed
in the dark (white spots). This is a natural effect, and is not eligible for warranty
replacement/repair of the CCD camera.
