High-Resolution Quality Inspection with SPECTRA HR

The high-resolution inspection system SPECTRA HR is used for quality inspection in the pharmaceutical industry. The use of 3CCD cameras provides an outstanding colour separation performance, allowing the inspection of products with difficult colour and contrast conditions. In combination with the largest software package, SPECTRA HR offers unique parameters and functions. Even the inspection of products with minimal differences in colour and shape in the same blister, transforms high resolution blister inspection into high speed. 


Highlights of the High-Resolution Colour Blister Inspection

  • All blister geometries and product / foil combinations can be detected
  • All parameters can be applied simultaneously, the illumination is homogeneous, reproducible and adjustable
  • Best hardware and comprehensive software package based on the QNX® real-time operating system
  • Inspection of different products and shapes possible in the same blister
  • Multi-camera systems for the most demanding inspection tasks
  • Qualified for Post-Seal inspection


Application Areas for High-Resolution Inspection

Examinable objects:
  • Tablets
  • Oblongs
  • Coated tablets
  • Hard and soft gelatine capsules
  • Medical strips
  • Sealed products
  • Special shapes
  • Dialpack etc.
Inspection criteria:
  • Contaminations
  • Colour
  • Presence
  • Size
  • Shape
  • Position
  • Perimeter
  • Fragments
  • Overfilling
  • Surface defects
  • Serial defects
  • Overprint


Numerous Application Possibilities with SPECTRA HR

Japanese Quality

By using several cameras, product control can also be carried out under Japanese quality standards. The colour system recognises 16 million colours even in three-shift operation at high belt speed. For Japan Quality Blister Inspection, a water cooling system is installed to keep the cameras at optimum operating temperature. Thanks to the high resolution and constant camera temperature, even the smallest contamination and defects can be reliably detected.


Hormonal preparations are a particular challenge because the same blister often contains tablets with minimal colour differences or even shapes. The high-resolution blister inspection system even detects colour differences that are nearly invisible to the human eye. No other system offers such accuracy and reliability. The SPECTRA HR software is equipped with improved shape recognition algorithms. By using several cameras, different products in the same blister as well as different shapes with the smallest differences in shape can be reliably detected.

Bulk Inspection

The inspection of bulk products serves to detect foreign products, fragments and foreign particles and their ejection. The bulkware solution can be installed on all common models of tablet counting machines with vibratory feed but also on drum filling machines.


Safety, Variety and High Speed thanks to High-Resolution Colour Blister Inspection

The use of the QNX® real-time operating system enables the fastest signal processing and high reliability.

Safety is increased by full 21 CFR Part 11 compliance - all format versions are stored separately. The image memory works with 10 images, on the basis of which an individual system suggestion for parameter limits is automatically generated. This offers higher security and easier operation compared to standard limits that can be adjusted by the user.

The modular design allows for expansion to meet future, increasing requirements. The system is thus future-proof.

Multi-camera systems are used to increase the resolution. The multiplexer can process up to 15 cameras. For highest colour accuracy a water cooling system is installed.

The controllability of the lighting and the guided learning run make the system adaptable for almost all product-film combinations and blister geometries. Only for special applications is sampling by scanware necessary


Comprehensive Software for optimal Bister Inspection Results

The software enables highest color separation with advanced options. The software works in real-time thanks to the use of QNX®. All functions can be used simultaneously - without loss of speed.

SPECTRA HR offers outstanding software functions, such as:

  • Filling statistics and production documentation
  • Configurable machine stops
  • Diagnosis for colour, pocket, blister and error images
  • Comprehensive Audit Trail
  • Special algorithms such as X-Y measurement, detection of protruding objects -even the most difficult applications are mastered
  • The detection of protruding objects reduces ejection. High standing objects are identified as correct instead of ejecting them as too small

The use of X-Y measurement is useful for various types of products, including medical strips. In the case of capsules with heterogeneous fillings, different positions of the product can be evaluated.

On intermittent machines, the trigger time varies depending on the belt speed and other technical factors. These are compensated by the automatic mask tracking.

Products with different shapes in the same blister can be checked simultaneously. Product-specific tolerances are set for this.


Best Hardware in Highest Quality

The Camera Link interface enables the low-interference data exchange of large data volumes. In addition, it enables significantly longer cable lengths compared to USB and FireWire. Due to the high performance of the evaluation unit, all parameters can be used simultaneously.
