Sequoia Scientific LISST-Holo2

• Submersible in-line holography
• New: Up to 20Hz continuous hologram capture
• New: Internal 237 GB data storage
• New: Internal rechargeable battery, (or external power for lab use)
• New: Faster processing, faster than the competition per unit volume imaged.
• New: An algorithm that ranks holograms by the richness of imagery in them
• Large volume viewed each image
• Programmable data collection

Automated Batch or Detail hologram processingThe LISST-Holo2 advances the technology that was built into the original LISST-Holo. It can capture holograms 100X faster which makes it the fastest. A 237 GB internal memory stores upto 118,000 holograms. The high speed hologram capture permits study of phenomena such as thin layers. Users often wonder how to make a quick assessment of these 10’s of thousands of holograms. Sequoia has pioneered a ranking algorithm. You can now see your holograms ranked by the richness of imagery in them.

Unlike other submersible holography systems, we have now incorporated a powerful rechargeable NiMH battery within the same original housing. This instrument is self-contained, ready to be programmed and used.

The LISST-Holo2 views the largest volume per image of competing systems. Processing speed per unit volume imaged is faster than the competing system.

Data processing software is included. Holo-Batch processes a selected group of holograms, whereas Holo-Detail permits detailed manual study of individual holograms. Processed holograms produce crisp in-focus images on a plane. Computed size distribution of particles is also output.

The large open path of the LISST-Holo2 allows particles to freely pass through the sample volume with minimal disruption.
