Digital Holographic Microscopy (DHM®) offers solutions for static and dynamic 3D characterization in material science, MEMS analysis, and life science applications.
Available in Reflection Mode (DHM R) and Transmission Mode (DHM T). DHM cameras available to be attached to the side port of your fluorescence microscope. DHM® is more than a standard optical profilometer as it enables dynamic measurement within vertical ranges from nanometers to hundreds of microns with sub-nanometric vertical resolution.
The DHM® technology and products have been developed by Lyncée Tec, Switzerland and starting with January 2025 Lyncée Tec SA is a Park Systems Company
Reflection DHM® model (DHM R)
Available with up to three laser sources, defined by the number and combination of wavelengths
They are ideal for measuring totally and partially reflecting objects with ability to work with low reflective interfaces (down to less than 1% reflectivity)
The high acquisition rate and ease of use make them ideal instruments for:
- accurate optical topography measurements
- rapid routine inspections
- automated industrial quality control as well as innovative R&D applications
- particularly for dynamic observations
- compatible with the optional Stroboscopic module and the post-analysis software for MEMS analysis and Reflectometry analysis
The DHM® are compatible with a large range of optional motorized stages.
Each DHM® can be delivered with its own structure to hold it, or as a head only, to be mounted on other structures or on production lines.
Possibility to offer you customized OEM systems.

Transmision DHM® model (DHM T)
Available in two configurations: DHM® T-1000 operating with a single laser, and DHM® T-2100 operating with two lasers.
Designed for measuring transparent or semi-transparent samples.
DHM T 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.
Ideal instruments for:
- high content screening
- time lapse measurements
- diagnostic.
- fluorescence measurements for fluorescence module
Compatible with motorized stages and with a large choice of accessories for working with living cells
DHM T 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
- characterization of micro-fluidics devices and 3D- particle flow velocimetry
Compatible with motorized stages, stroboscopic module and the post-analysis software for MEMS analysis

Holographic MEMS analyzer
The holographic MEMS analyzer solution provides time sequences of the successive 3D topographies of a MEMS along its driving signal. In- and out-of-plane displacements and frequency response can be analyzed at any location within the measurement field of view
It is an ideal tool for:
- a non-scanning method for reduced characterization time
- measurement of samples that cannot be characterized with other techniques
Includes a complete characterization environment including:
- Platforms for sample probing
- Vacuum and thermal chambers
- Signal generator for MEMS with excitation up to 25 MHz
- Recording of electrical response
- DHM® T and R series for the 3D topography time sequence acquisition
- Stroboscopic unit for measurement and MEMS excitation synchronization
- MEMSTool software enables efficient analysis of 3D topography time-sequences in term of:
- Out-of-plane displacement from 5 pm to 50 microns
- In-plane displacement from 1 nm (sub-pixel algorithms) to 5 mm
- Bode and Fourier frequency response analysis
- Vibration maps
