Color measurement of foils, films and plastic plates

Is a film clear or milky, translucent, transparent or cloudy? The appearance of a film differs depending on the raw material, composition and intended use. Spectrophotometers can precisely determine the amount of light that is transmitted, absorbed or scattered. With measurement technology from HunterLab, deviations are detected quickly and costs are minimized. In stationary haze/color measuring devices, samples of (technical) foils, films or plates are subjected to standard-compliant quality control, while foils on rolls are tested in real time using online/inline measuring devices.

Our solutions for your products:

Vista

Standard-compliant testing of color and turbidity
  • Color & Haze

    Simultaneous measurement of color in transmission and haze.
  • Enough space for samples

    Large transmission shaft for many sizes and types of cuvettes, vials and foils.
  • Integrated QC software

    The EasyMatch QC Essentials quality control software is integrated into the device and provides all the required color indices, color numbers and metrics.
Aeros

    Illumination range of 400-700 nm and long-life LED combination module
  • Smart user interface

    Your measurement results can be easily transferred to existing LIMS or SPC systems.
  • Uncomplicated & precise

    Simple "one touch" measurement reduces training time, optimizes the workflow and increases your productivity.

UltraScan VIS

Color measurement of opaque and translucent samples
  • Reflection

    Measuring apertures with 25.4 mm and 9.35 mm provide the prerequisite for precise measurement results in reflection.
  • Transmission

    Large transmission compartment with 100 mm depth for measurements in total and regular transmission to determine color/opacity.
  • Construction & function

    The device complies with the internationally recognized color measurement standards of ASTM, DIN and ISO.

UltraScan VIS
  • 10 nm resolution

    With a true optical resolution of 10 nm, the UltraScan VIS offers high accuracy for measurements on liquids and solutions.
  • CIE-recommended measuring range

    The UltraScan VIS covers the wavelength range from 360 nm to 780 nm recommended by the CIE.
  • Robust

    Solid construction with optical bench and protected transmission range thanks to sliding cover.

  • Contactless

    The sensor detects the sample directly on the surface, without contact, perfect for products of different heights.
  • Versatile

    The SpectraTrend is able to measure the color of granules, slabs, baked goods, fiber cement and much more.
  • Software evaluation

    Evaluation and process control can be carried out in the appropriate colorWorkbench software.
SpectraTrend HT
  • Precise sensor

    Monitoring with 5 measurements per second for color and height fluctuations.
  • Connectivity

    Measurement results are easily transferred to a PC, network and/or PLC and further processed in QA software.
  • Resistant

    Robust industrial design in NEMA4/IP66 approved housing with optional stainless steel housing for use in the food industry.

Application example:

Color measurement of clear films with the Vista spectrophotometer

Today, a variety of films are produced for the packaging and coating industry, as well as for medical technology and building materials, e.g. thermoplastic polyurethane films (TPU films). The exact determination of the color and the examination of the turbidity in the form of the Haz measurement according to ASTM D1003 is very important in development and quality management. Instrumental color measurement in transmission is now the standard procedure for transparent films. Until now, however, haze measurement usually had to be carried out using a second device. HunterLab’s color measurement offers the perfect solution for determining exact color values and the haze value of film at...

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
