Contact persons:
Dipl.-Ing. Tobias Porsch; Dr.-Ing. Udo Krüger

The centrepiece of the whole LMK family is the luminance measuring videophotometer LMK 98. The current basic type LMK 98-4 is also on offer as LMK HighRes with a bigger imaging resolution.
Also with this version comes the stable and robust CameraLink interface (industrial standard). This Interface is available for the usage with a Standard-PC and with a Notebook-PC.

The camera type LMK 98 is an advanced digital CCD camera system including a very precise analogue electronic system for signal generation.

Each camera has its own full filter specially calculated and manufactured for your CCD matrix, allowing a high-quality V(λ) adaptation for determining the luminances.
