Lyncee Tec's (Lausanne, Switzerland) digital holographic microscopes capture 3-D optical images in real time at up to 50,000 frames per second (fps), thus eliminating the need for expensive and bulky isolation equipment. Two major advantages over interferometric instruments are real time data capture (including movies of biological processes, for instance), and vertical range.
The instrument is available in reflective mode (DHM R1000) and transmission mode (DHM T1000) models, with lateral resolution down to 300 nm and vertical temporal resolution of 0.2 nm in air. The field of view is objective limited with a maximum of 4.40 mm on a sample size up to 200 mm x 123 mm. Both models come with software that enables extensive 2-D and 3-D analysis of the captured images.
According to George C. McMurtry, CEO of NanoAndMore USA, Inc. (which distributes the instruments in the US), the DHM R1000 has some unique characteristics--among them a stroboscopic mode operating at 25MHz, which allows stop-action in the nanosecond range. This can map movement and show the influence of changing variables in real-time, and can generate movies showing changes as the variables are modified.

For Life- and Material Science applications
This instrument is unique in that it captures 3-D optical images in real time at up to 50,000 fps. This quick capture eliminates the need for expensive and bulky isolation equipment and allows the instrument to work on a noisy manufacturing floor without concern for vibration as well as a quiet research laboratory. Two major advantages over interferometric instruments are the real time data capture (including such as movies of MEMS movement and biological materials), and the vertical range. Resolution is 300 nm lateral and 0.2 nm vertical.
There are two models, one for reflective mode (DHM R1000) and one for transmission mode (DHM T1000) with lateral resolution down to 300 nm and vertical temporal resolution of 0.2 nm in air. The field of view is objective limited with a maximum of 4.40 mm on a sample size up to 200 mm x 123 mm. Both models come with Koala software that includes extensive 2-D and 3-D analysis of the captured images. The flexibility of this approach and simplicity of operation allows the instruments to work as well for life science as they do for materials science.
