LUMI-LAB Series

The devices of the LUMI-LAB series are primarily used with granulate samples and powder samples with a very high marker content. The tau value of the samples to be examined is determined in individual wavelength sections (TAU spectrometer).
The following wavelength ranges are available as sources of excitation light: UVA, blue, red, NIR. Depending on the marker type, the secondary emission is located in the visible wavelength range or in the NIR range:

UVA excitation → VIS
Blue excitation → NIR
Red excitation → NIR
NIR excitation → NIR

LUMI-TAU Series

The LUMI-TAU-LAB series is used to detect phosphorescent (luminescent) markers added to the respective plastic granulate. The quality of the marked plastic granulate can be checked in a timely fashion when taking pellet samples during production.
Different light sources are available to excite the respective marker: UVA, blue, green, red, NIR. Depending on the marker type, the secondary emission is located in the visible wavelength range or in the NIR range:

UVA excitation → VIS
Blue excitation → NIR
Green excitation → NIR
Red excitation → NIR
NIR excitation → NIR

MULTI-RANGE-LAB Series:

SINGLE-RANGE-LAB Series (single-channel sensors)
With the help of the single-channel sensors of the SINGLE-RANGE-LAB series, the fluorescence of pellet samples can already be determined during production (fluorescent markers are added to the plastic granulate). Moreover, this device series is also suitable for determining the phosphorescence of the phosphorescent markers added to the plastic granulate by determining the cut-off frequency of the optical low-pass filter. Pellets produced from marked recyclates can also be examined in terms of fluorescence and phosphorescence.
The following wavelength ranges are available as excitation light sources for activating the respective markers used: UVA, blue, green, red. The secondary response (fluorescence or phosphorescence) takes place in the visible wavelength range and the NIR range:

UVA excitation → VIS + NIR detector
Blue excitation → VIS (from yellow) + NIR detector
Green excitation → VIS (from red) + NIR detector
Red excitation → NIR- detector

DOUBLE-RANGE-LAB Series (two-channel sensors)
The two-channel sensors of the DOUBLE-RANGE-LAB series each have two sources of excitation light and two detection ranges. Two different markers can be detected consecutively in the respective samples, if they are present. Both the fluorescent markers added to the plastic granulate and the phosphorescent (luminescent) markers can be measured. Quality control can already be carried out during the production of the pellets by taking a pellet sample.
The following wavelength ranges are available as excitation light sources to activate the markers used: UVA, blue, green, red. The respective secondary response takes place in both the visible wavelength range and the NIR range (depending on the marker type):

UVA/blue excitation → VIS + NIR/VIS (from yellow) + NIR
UVA/red excitation → VIS + NIR/NIR
Blue/red excitation → VIS (from yellow) + NIR/NIR

TRIPLE-RANGE-LAB Series (three range sensors)
The three range sensors of the TRIPLE-RANGE-LAB series can be excited with a light source. A RGB detector (red/green/blue) divides the visible range into three areas. The fluorescent markers added to the plastic granulate can be monitored during production via pellet sampling.
The following wavelength ranges are available as excitation light sources to activate the fluorescent markers used: UVA, blue. The respective secondary response takes place in both the visible wavelength range and the upper visible wavelength range (depending on the marker type).

UVA excitation → VIS
Blue excitation → VIS (from yellow)

Imaging systems

LUMI-STAR-INLINE Series
The devices of the LUMI-STAR-INLINE series are imaging systems. Fluorescent marker particles introduced into the object to be examined are excited in the UVA range or in the blue wavelength range and reproduced in the recorded video image. The particle distribution is purely random and therefore unique for each object. This particle distribution in the image is stored in the system in coded form (cloud-based system) and stored as a reference (UUID code).
Light sources in the following wavelength ranges are available as sources of excitation light: UVA, blue, red. The secondary emission follows (depending on the marker) in the VIS or in the NIR range:

UVA excitation → VIS response
Blue excitation → VIS (from yellow) or NIR
Red excitation → NIR

LUMI-STAR-MOBILE series

The devices of the LUMI-STAR-MOBILE series are mobile imaging systems. The fluorescent marker particles introduced into a product are captured on an image in the excited state. After recording and subsequent coding, the comparison is made with the references stored in the cloud. The corresponding UUID code will be issued following a match. This enables a product to be clearly distinguished from a multitude of products even of exactly the same shape and color.
Light sources in the following wavelength ranges are available as sources of excitation light: UVA, blue, green. The secondary emission is issued (depending on the marker) in the VIS and the upper VIS range (from yellow).

UVA excitation → VIS response
Blue excitation → VIS (from yellow)Green excitation → VIS (from red)

Inline detectors

Inline detectors for automated checking of product markers during the production process

LUMI-TAU-INLINE Series
The systems of the LUMI-TAU-INLINE series are used to monitor the uniform addition of product markers into the base material. Both switching signals and an analog signal are available at the output.
The LUMI-TAU-INLINE series can be used to detect phosphorescent (luminescent) markers. The following wavelength ranges are available as sources of excitation light: UVA, blue, green, red, NIR. The secondary emission then follows (depending on the marker) in the VIS or in the NIR spectrum:

UVA excitation → VIS response
Blue excitation → NIR response
Green excitation → NIR response
Red excitation → NIR response
NIR excitation → NIR response

LUMI-TAU-MOBILE series

The devices of the LUMI-TAU-MOBILE series were designed for mobile use. The majority of types within this product group are equipped with both a battery integrated in the hand-held device and a Bluetooth® interface. The most powerful XL series also has a WiFi interface. These devices enable detection of the lowest phosphorescent marker concentrations. The fiber optic versions (FIO types) are very well suited for the detection of selective markings.
Light sources in the following wavelength ranges are available as sources of excitation light: UVA, blue, green, red, NIR. The secondary emission follows (depending on the marker) in the VIS or in the NIR range.

UUVA excitation → VIS response
Blue excitation → NIR response
Green excitation → NIR response
Red excitation → NIR response
NIR excitation → NIR response

Taggant Technology TAGTEC

TAGTEC is a groundbreaking, market-ready technology, that gives plastics a distinctive signature identity similar to a fingerprint.

Markers (taggant particles) added to the masterbatch create an intelligent plastic that can be used in a variety of applications. It carries the added information like DNA. Which information, you define.

The TAGTEC advantages:
Product safety
Material detection
Single part detection

The markers, which can be activated by sensor technology and are added during the production of plastics, enable the secure transmission of product- or material-specific information. Just as if the product could tell where and how it was made, what it contains or whether it is an original or an imitation.

TAGTEC uses the principles of encryption (coding) and decryption (decoding). The marker-bound, encrypted information can be decoded using patented technology via special sensor technology - reliable and forgery-proof.

In order to decode the embedded information, two methods are available:

STAR, in which the reading takes place on a defined area, for example in a bottle cap. A sensor connected to a cloud illuminates the previously defined area, reads out the product information stored there and transmits it to the cloud.
TAU is the name of the system in which information can be read at any point on the product. The response signal depends on the mixture of taggant particles.

Solutions tailored and optimised to …
Necessary product safety
Product-specific applications
Combined functionalities

The worldwide economic damage caused by counterfeit products is immense. This problem was the starting point and incentive for the development of TAGTEC.

Protect your products with TAGTEC technology! The method is based on the combination of security markers and sensors. By selecting the marker-sensor pairings, you determine the level of security you require.
