Camera photometer

The luca'lux system extension expands the luca system with a quick and easy measurement of illuminance or illuminance distributions.
The luminaire or optical system is directed onto a diffusely scattering measuring surface. Both the reflection and transmission measurement surface is available. With the help of a convenient software wizard (Calibration Wizard), the system is calibrated against a traceable transfer standard.
The complete measurement of the illuminance distribution of a luminaire or e.g. a car headlight is then carried out in just a few seconds.

luca'lux

Spatially resolved measurement of illuminance and luminous intensity distributions

The software and hardware enhancement luca'lux enables the fast and easy measurement of illuminance and luminous intensity distributions respectively.
The measurement is spatially taken in one shot against a reflecting or transmitting screen. The entire measurement of the illuminance distribution of a luminaire or an optical system is carried out within seconds. The software provides a comfortable assistant (calibration wizard) calibrating the system with respect to a traceable transfer standard.

Predefined evaluation masks compare the measuring results with the desired standards, such as ECE, SAE, etc. in lightning speed. The self-explanatory background coloring immediately reveals whether all test points lie within the prescribed area. Efficiency degrees are specified by integrating arbitrary areas of the measurement to define the luminous flux. The system stands out for significant evaluations and very short measuring times and is most suitable for production control of photometric data and quick development verifications.

The system can be used in measuring distances from 0.5 m up to 25 m. A conversion of smaller measuring distances to the 25 m distance is easily possible.

For the measurement of tail lights, the measurement is transformed from spatial to angular space so that the luminous intensities can be evaluated directly as a function of the emission angle. A fast evaluation against the corresponding standards is of course possible.
For the determination of efficiencies, any areas of the measurement can be integrated to determine the useful luminous flux.

Any areas of the measurement can be integrated to determine the luminous flux and thus enable the determination of efficiencies.
The photometer system convinces with meaningful evaluations and very short measuring times. The luca'lux photometer is ideal for production control of photometric data and fast development verifications.
