Digital holographic microscopy (DHM) is an interferometry-based variant of quantitative phase imaging (QPI) that typically uses a laser as a coherent light source and provides QPI by detecting specimen-induced optical path length changes against the surrounding environment. DHM can be modularly integrated into common optical microscopes which allows its integration as a label-free imaging modality in research laboratories.
There are essentially 5 types of solid state laser technology which meet the need for long coherence length in order to write holograms or HOE´s. All offering unique wavelengths, either fixed or tunable and output powers from 10´s mW up to multiple watts.
Through the well-known Swedish laser manufacturer Cobolt AB, a proven supplier of high performance lasers of more than 15 years, HÜBNER Photonics division offers one of the industry’s broadest ranges of compact single-frequency CW lasers, diode lasers, multi-line lasers and Q-switched lasers across the full UV-Visible-NIR spectrum.
