Display-MeterTM
a novel family of portable instruments for evaluation of the visual performance of emissive, transmissive and reflective displays:


  • luminance, contrast, spectra and chromaticity versus viewing-direction,
  • luminance dynamics (image formation time, flicker, image sticking, etc.) versus viewing-direction,
  • high-resolution directional scanning option (for e.g. BRDF evaluation).

 



Display-Dome TM
a novel concept for fast measurement of the electro-optical properties of reflective displays under a variety of different illumination conditions versus viewing-direction.



LINQ TM
lightsource with adjustable luminance (1:65 000) at extreme spectral stability.



OTR-3 TM
optical transient recorder for measurement of temporal luminance variations, for evaluation of transition times (step or impulse response, flicker, etc.


 

Photo-Spect TM
a range of micro-spectrometers for high-performance color measurement based on reflective and emissive spectra. With electro-magnetic shutter for dark-signal correction and complete photometric calibration.

MultiSpect TM
multichannel spectrometers for simultaneous acquisition of up to 16 input-channels (spectra) combined with fast photometric detectors.


MultiSpect-8 TM
the first multichannel microspectrometer with integrated shutter for measurement of the spectra of emissive and reflective objects.

MultiSpect-8 datasheet

Simultaneous acquisition of up to 9 spectra can be used for measuring the same location on a sample from 9 directions or measuring a sample at 9 loacations at the same time. It can also be used for simultaneous monitoring of the light source(s) during the measurement of reflective samples




Light sources
with incandescent or discharge lamps, LEDs, adjustable and stabilized.



Illumination systems
point-sources, conical and directional sources, "diffuse" sources and special combinations thereof.


New: Reference TickerTM
This device emulates a single line of a matrix-organized electronic visual display with an exactly controlled timing. It is designed for performance checking and calibration of measurement devices for motion-blur analysis and for research of perception of motion by the human visual system.

BSDF-Meter

Based on a novel approach for measurement and evaluation scattering, the BSDF-Meter is now available for simple, fast and effective measurement and evaluation of light scattering in general (bidirectional scattering distribution function, BSDF) and specifically for application to electronic displays (e.g. reflection classes according to ISO 13406-2).


The method is based on the measurement of the lateral distribution of reflected luminance with an imaging photometer. After numerical transformation of the measured luminance distribution the characteristics of the BRDF/BSDF of the sample are obtained with high directional resolution within a limited angular range centered about the specular direction. Due to the absence of moving parts the method exhibits no sensitivity with respect to variations of the geometry parameters and is thus very robust.
