Lyncée Tec's Transmission DHM® measures the optical path difference of a beam travelling through samples .

For measurements of micro-optical components, microfluidic devices, and defects or particles inside transparent samples, Transmission DHM® systems are usually the optimal choice.

In biological imaging the pioneer users of DHM® have demonstrated through seminal publications the interpretation of DHM® measurements in terms of underlying biological processes. Transmission DHM® systems are the best choice for such cellular applications.

The Transmission DHM®-Series are designed for measuring transparent or semi-transparent samples. There are available in two configurations : DHM® T-1000 operating with a single laser, and DHM® T-2100 operating with two lasers.

In life sciences

DHM®-T provides precise Quantitative Phase Measurements (QPM) of living cell cultures up to confluence, without the use of any contrast agent and with very low illumination power. The DHM®-T is an ideal instruments for high content screening, time lapse measurements and diagnostic. Used in conjunction with the optional fluorescence module, it enables simultaneous DHM® and fluorescence measurements. It is  compatible with motorized stages. and with a large choice of accessories for working with living cells.

In material sciences

DHM®-T measures specimen shape and surface, as well as material optical parameters, internal structure and defects. It is an ideal tool for characterization of micro optics, providing shape, refractive index and optical transfer function. Refractive index liquids can be used for characterization of steep slope samples like micro-corner cubes and Fresnel lenses among other. Other major applications are characterization of micro-fluidics devices and 3D- particle flow velocimetry. Systems are compatible with motorized stagesstroboscopic module and the post-analysis software for MEMS analysis.

Lyncée Tec has developed the DHM® technology from its invention to its maturity as a product and has the competence and flexibility to offer you customized and OEM systems.
