Purpose

• Ultraviolet viewing detectors DORS 100 series are intended for visual authenticity control of world currencies.
• The detectors can be used for visual authenticity control of identification documents, securities, serially numbered forms, duty stamps and other security printing documents.

Distinguishing features

• Wide viewing area with the measuring scale for the simple control in the white transmitted light
  
• Powerful UV-light source (total capacity12 W).
• Special slot in a rear panel for placement of large documents. Dark colour of the inner part of a detector guarantees absence of light flares in bright room.

Types of control

• Ultraviolet control of absence of background luminescence of banknote paper and presence of luminescent UV-marks, fibers and threads.
• Reflected white light control (for DORS 145) of printing types and methods, printing defects and possible erasures, image fragments made by optically variable inks, latent images, security holograms.
• Transmitted white light control (for DORS 125/135 /145) of watermarks, security threads, microperforation, front-to-back registers.
• Size control (for DORS 125/135/145) of a banknote or dimensions of a missed fragment.

Types of control (by means of external devices)

• Reflected oblique white light control with 10x magnification (with DORS 10, for DORS 135/145) for detailed investigation of printing types and methods, microprinting, microperforation, printing defects and erasures.
• Magnetic control (with DORS 15, for DORS 135/145) of presence of special protective marks, texts and images made by ferromagnetic inks.
• Infrared control (with DORS 15, for DORS 135/145) of presence and allocation of fragments printed with IR metameric ink.
