A Self-Adjusting, Holographic & Tomographic Microscope

Our tomographic holographic 3D microscope is the result of years of work and development. Through a combination of holography and rotational scanning the system detects changes to light as it propagates through the cell, i.e. the 4D distribution of the physical refractive index (RI) within the cell.

The sample is positioned between a high-numerical-aperture air objective beneath the sample and a rotational illumination arm above. Green light (520 nm) from a laser diode is split into sample and reference beams. The sample is illuminated with a laser beam inclined at 45° which rotates around the sample 360°. A series of holograms is recorded on a digital camera by combining the beam that has passed through the sample with the reference beam. 

 

Unibody Concept

The revolutionary intuition we had, at Nanolive, was to reduce structural complexity to one unique basic component – a unibody industrially derived from a single piece of aluminum. Thanks to this simple design, the 3D Cell Explorer is thin, light, simple and stable.

Self-Adjusting

To achieve optimal results for every measurement, the optics of our microscope are completely self-adjusting on sample conditions (e.g. media evaporation).

 

Low Power Laser

Our 3D Cell Explorer uses a low power laser (Laser class 1: 0.2mW/mm2): No goggles required.

 

Fast Acquisition

A full 3D image of your cell will be loaded to your screen within two seconds.

 

 

 

Long Term Observation

The microscope stage is perfectly compatible with classical top stage incubators. You are able to observe your cell’s behavior in their natural environment (5% CO2 & 37°C).
