LDM-9810

Precision luminance detector head 

For the measurement of spot luminance, Gigahertz-Optik GmbH offers the LDM-9810 viewfinder optics that can be combined with the PD-16VL01 photometer detector. 

Adjustable measurement field angles 

The luminance detector head has 3 adjustable measurement field angles with 20 minutes, 1 degree and 6 degrees which can be setup at the same measurement distance. 

High-quality focusable lens with viewfinder 

The LDM-9810 viewfinder has a high-quality, chromatically corrected lens. The measurement distance ranges from 0.33m to infinity. Measurement field targeting and focusing can be done using the viewfinder. 

Close-up lenses for measurement spots up to 0.1mm 

The optional LDM-98Z-NL close-up lens enables 1:1 to 2:1 mappings. Measurement field sizes starting from the 0.1mm range make it possible to perform luminance measurements over very tiny illuminated surfaces. 

Photometric DIN 532 T7 quality class A 

The matching of the photometric responsivity of the PD-16VL01 detector combined with the LDM-9810 viewfinder corresponds to the DIN 5032 quality class A. 

Extensive selection of optometers 

The LDM-9810 luminance measurement head with the PD-16VL01 can be combined with all optometers from Gigahertz-Optik. 

Traceable calibration 

Calibration of the luminance responsivity in A/(cd/m²) is performed by Gigahertz-Optik‘s calibration laboratory for optical measurands. The details provided in the calibration certificate are as stipulated by the ISO 17025 specifications.
