About us

The company Czibula & Grundmann was founded in the year 2000. After our activity for many decades in the area of photometry  and radiometry it was our aim to realize an own enterprise for the development and production of highly precise, high-quality and complex measuring systems.

On these pages we would like to introduce ourselves and our product range. Please understand that the contents of our website cannot cover all our products and services due to the multiplicity.



During the last 6 years we have developed numerous standard devices, whereby the modular usability of these devices was in the center of our attention.

This allowed in parallel to develop a multiplicity of customized measuring systems.

Our customers are considerable manufacturers of lamps and luminaires as well as institutions in the range of the light and application of radiation.

By the successful combination of our abilities in the areas fine mechanics, optics, electronics and software as well as our commitment we convinced our customers.



Our laboratory is equipped with a high-end spectroradiometer for the measurement of spectral and spatial radiation sensitivity.

This gives us the possibility to produce precise sensors for a multiplicity of spectral  functions; in particular naturally the V(λ) function.

The calibration of our sensors and measuring instruments on photometric quantities is done by standards which are traceable to our national institute of standards (PTB).



Motivated by the past success of our products and services we look forward to further challenges given by special measurement and automation tasks of our customers.
