•
LED light sources are relatively inexpensive, provide a uniform field, and longer life
span compared to other light sources. However, they also require a camera with
excellent sensitivity, such as the Spyder3 GEV camera.
•
Halogen light sources generally provide very little blue relative to infrared light (IR).
•
Fiber-optic light distribution systems generally transmit very little blue relative to IR.
•
Some light sources age; over their life span they produce less light. This aging may
not be uniform—a light source may produce progressively less light in some areas of
the spectrum but not others.
Filters
CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent
infrared from distorting the images you scan, use a “hot mirror” or IR cutoff filter that
transmits visible wavelengths but does not transmit wavelengths over 750nm. Examples
are the Schneider Optics™ B+W 489, which includes a mounting ring, the CORION™ LS-
750, which does not include a mounting ring, and the CORION™ HR-750 series hot
mirror.
2.4 Electrical Interface
The Spyder3 GEV cameras have been designed for EMC compliance. The test setup has
been verified to the following EMC standards:
•
CISPR-11:2004
•
EN 55011:2003
•
EN 61326:2002
To achieve EMC compliance, follow these specific guidelines:
•
Ensure that all cable shields have 360
°
electrical connection to the connector.
•
Fasten and secure all connectors.
The EMC compliance is achieved with the use of shielded CAT5e or CAT6 Ethernet
cables
