Raman Spectrometer Integration
LabVIEW was used to integrate a microscope camera, an automated stage, four Thorlab's motors, a Lakeshore temperature controller and a Horiba Raman Spectrometer.
For integration, an efficient user interface was designed, a script engine developed, and a database using a MySQL server developed. To complement data analysis, a special GUI was developed in Igor PRO software to extract past experimental data from the MySQL server.
The following papers were published using this software integration:
- Benshalom N, Reuveni G, Korobko R, Yaffe O, and Hellman O. Dielectric response of rock-salt crystals at finite temperatures from first principles. Phys. Rev. Mat. 03/2022

Photo Multiplier Tube integration with a two-photon LSM 880 NLO Zeiss Microscope
The PL collected by the objective was deviated using a dichroic mirror and directed to a Si PhotoMultiplier Tube (PMT) sensitive to 750-900 nm light. The electrical signal was directed to an amplifier and passed to a NI 6343 card as well as the microscope pixel and line clocks. The three digitalized signals were then passed to a computer and elaborated by an in-house LabVIEW program that rebuilt the confocal microscopy image.
The following paper stemmed from this software-hardware integration:
Self-Healing and Light-Soaking in MAPbI3: The Effect of H2O Ceratti D. R., Tenne R., Bartezzaghi, Cremonesi L., Segev L., Kalchenko V., Oron D., Potenza M.A.C, Hodes G., Cahen D. (2022) Advanced materials (Weinheim)

Microfluidic and a Nikon Microscope Integration
A micromanager code controlling a microfluidic system was integrated with a Nikon microscope for imaging while operating the microfluidic device.
This integration has led to a Nature Biotechnology paper:
Fedyuk, V., Erez, N., Furth, N. et al. Multiplexed, single-molecule, epigenetic analysis of plasma-isolated nucleosomes for cancer diagnostics. Nat Biotechnol (2022).
