Verbesserung einer Computer-vision Kamera:

"Marcel supported us on a time-sensitive optical system redesign where the challenge was to preserve image brightness and readability at very short exposures while remaining robust to temperature changes and mechanical tolerances. He produced quantitative analysis (DoF, light budgets, focus sensitivity), recommended concrete lens/aperture options, and guided validation tests in our lab. What I appreciated most was that he delivered exactly what he promised—clear, practical outcomes we could implement right away. Highly recommended for complex vision-system work." -- Chahal Neema, Vimaan

Troubleshooting radiometrischer Messungen von nah-infraroten LEDs:

"We needed a person with an academic background. We could not have chosen better than Marcel. His approach to the problem and suggested solutions helped us establish our quality and test structures. Thanks Marcel, and would be happy to work again." -- Tekant Gündoğan, Neuronic
