Barcode
A series of lines of varying width, which are separated by empty spaces and represent
numeric or alphanumeric data in a machine readable form. Basically, a barcode
symbol consists of a quiet area zone at the start, a start character, data or contents
characters, check digit (if used), stop character and a subsequent quiet area zone.
Within this basic structure, all the readable symbologies use their own format.

CDRH (Center for Devices and Radiological Health)
The Center for Devices and Radiological Health (an agency belonging to the
American health authority FDA) is responsible for safety guidelines and radiation limit
values of laser devices. VISOLUX devices meet the requirements stipulated by
CDRH.
CD SQUARE™
CD SQUARE™ provides useful information pertaining to the label position and the
form of the object, which were determined in the read phase of the barcode. This
innovative technology indicates the area which contains the code and measures the
distance of the code to the reader.
