TYPICAL SPECTRAL RESPONSE
COSMETIC SPECIFICATION
Maximum allowed defect levels are indicated below.
Grade 5
devices are also available as electrical samples. These are confirmed to have working outputs and will
nominally provide an image. Not all parameters are guaranteed to be tested or provided and the image quality may
be worse than that of a grade 1.
DEFINITIONS
White spots
A Bright Defect in Darkness is defined as any pixel whose mean response in darkness
exceeds 100 times the specification for the maximum dark signal, at the test temperature.
Black spots
A dark defect at high light level is defined as any pixel whose mean photo response is less
than 90% of the local mean at a signal level of approximately 50% of image full well capacity.
White Column
defects
A Bright Columns in Darkness is defined as 9 or more consecutive pixels in any column,
whose mean response in darkness exceeds 10 times the specification for the maximum dark
signal at the test temperature.
Black Column
defects
A dark column at high light level is defined as any column containing 9 or more (not
necessarily consecutive) dark defects at high light level.
Traps
Pixels where charge is temporarily held. Traps are counted if they have a capacity greater
than 500 e
