Illumination color influence
WHITE…
Is the all-purpose version due to widest spectrum
Is most suitable for text or code printed on cardboard boxes
Suits best for presentation camera applications as
most people feel white light is least harmful
BLUE…
Is the perfect choice if maximum optical DOF is
required (f = >11…16)
Offers best performance if the pixel resolution is
challenging (1D code <1.5 ppm & 2D code < 2.0ppm, ppm – pixels per module)
Is not well-suitable for colored text or code printed on
cardboard boxes as the brown background turns black
RED…
Is used if mixed labels with white, yellow and red background
need to be read
Can be used if black text or code is printed on
cardboard boxes
Infra-
Red (IR)…
Suits best when people work close to cameras and shall
not be disturbed by flashing light – IR is invisible
Has highest ambient light resistance due to daylight block
filter usage
Delivers lower text and code resolution (1D <2 ppm & 2D < 3ppm)
Some material and even printed text or code is sometimes invisible to IR light
