Imaging colour measuring technique
Contact persons: Dipl.-Ing. Tobias Porsch; Dr.-Ing. Udo Krüger
The imaging analysis of light sources and illuminated scenes is getting more and more important.
The LMK 98-4 color / HighRes color camera is equipped with a filter wheel adapted to the color matching functions of the 2° CIE standard observer (CIE 1931) for color measurement. Thus, luminances and color coordinates can be measured in a spatially resolved way.
The filter wheel has 6 filter positions, with 4 filters being required for color measurement. Furthermore, the measuring system can be equipped with additional filters for the scotopic luminance V'(%u03BB), the circadian principal function C(%u03BB), with an IR filter (measurements in the NIR range %u03BB=780-1000 nm), the filter for blue light hazard (BLH) or a clear glass filter.

Imaging luminance measuring technique
Contact persons: Dipl.-Ing. Tobias Porsch; Dr.-Ing. Udo Krüger
The imaging analysis of light sources and illuminated scenes is getting more and more important. The complex evaluation of those scenes requires to know the luminance distribution. Solving the necessary measuring tasks by means of measuring devices working point by point either takes an enormous amount of time or is possible only within a coarse raster grid or is not possible at all. Thus, the development of CCD matrix cameras, has enabled the user to solve measuring problems such as measurements for glare evaluation according to the UGR method, the analysis of visibility conditions in the road traffic at night, immission evaluations of glare sources, the determination of contrasts in illumination situations (workplace) or directly on light sources (e.g. lamps/luminaires, displays, night design, indicators).
- measuring of luminous and illuminated surfaces
- determination of luminous and background-lit symbols
- data for simulations in the development of lamps, luminaires and headlamps
- photographing of complex illumination and light distribution situations
Advantages:
- complex evaluation of luminous and illuminated scenes by means of the photograph of an imaging luminance distribution
- simultaneous recording of a big number of connected geometrical data
Resulting data
- luminance distributions in measuring images L(x,y)
- derived lighting-engineering parameters such as illuminance distribution E(x,y) and luminous intensity distribution I(x,y)
- compatible statistical data (e.g. EXCEL®, MatLAB®, LabVIEW®)

Process PhotometersPUV3402 and PIR3502 ...
The Next Generation of On-Line Process Photometers.
Multiwave™ Process Photometers are designed to provide on-line measurements of gas or liquid components, in simple or complex process streams, for process control, product quality assurance, safety, catalyst protection and area monitoring.
The Multiwave™ is a fixed filter photometer that utilizes optical filters to make continuous measurements. The single beam, dual wavelength concept used in the Multiwave™ compensates for source and detector aging and the obstruction of cell windows, while allowing the sample cell to be isolated from the electronics.
The Multiwave™ design takes the single beam, dual wavelength concept one important step further, by adding up to eight filters to the filter wheel. This improved method provides more measurement solutions than a conventional single component process photometer. The use of multiple wavelengths enables the Multiwave™ to compensate for numerous interferences and perform multiple component applications.
The new Multiwave™ Process Photometers offer even more performance,
operating efficiency and versatility to the user. The Multiwave™ line features two basic models, each offering a wide range of applications capability.
PIR3502 Multiwave™ Photometers can be applied to Infrared and Near
Infrared measurements.
PUV3402 Multiwave™ Photometers are designed for the Ultraviolet and
Visible spectral regions.

The full determination of the data of luminaires and lamps becomes more and more important:
- Primary prerequisite of a correct illumination planning
- Simulation, development of luminaires and lamps
- Cataloging and presentation
The goniophotometer type RIGO801 utilizes imaging CCD measuring technique for determining ray data and luminous intensity distributions.
The correct determination of the luminous intensity distributions (Lid) of lamps and luminaires is performed far within their photometric limiting distance on the basis of image-resolved measurements of luminous intensity distributions. A CCD-camera is moved by a goniometer around the measuring object at rest on a spherical surface, with the radius of this sphere being fixed only by the field angle of the camera. Thus, the goniometer can also be installed in small laboratories.
Advantages:
- Full description of the light emission by ray data
- Small dimensions of the set-up
- Measuring in normal position
Resulting data:
- Luminous intensity distributions (LID)
- Ray data available in various formats (e.g. ASAP, SPEOS, LucidShape, LightTools, Zemax, SimuLux)
- Processing and archiving of the LVK data in a photometric database (LumCAT)
