About us

Holtra AB was founded in 2020, based on cutting-edge research at Chalmers and Gothenburg Universities, Sweden. The origin was an adaptation of a holographic microscope to selectively detect submicrometer gas bubbles in water and differentiate them from solid particles in the same sample. It was soon realized that the method is in general an extremely powerful tool for characterization of dispersed particles in the submicron size range.
