Nanolog – Steady State and Lifetime EEM Spectrofluorometer

The Nanolog® series of spectrofluorometers are specifically designed for research in nanotechnology and the frontiers of nanomaterials. A complete spectrum can be scanned as fast as a few milliseconds, and a full excitation emission matrix scan can be taken in just seconds.

Based on the world-wide proven technology of the Fluorolog®, the Nanolog detects fluorescence in the near-IR from 800 to 1700 nm (optional multi-channel detection to 2 µm, single-channel detection to 3 µm), with visible and UV options possible. With the Nanolog comes specially designed software called Nanosizer, ideal for classifying SWNTs, Quantum Dots and performing energy transfer calculations. Saving custom experimental routines and instrument layouts has never been easier.

Nanolog: Modular Multi-channel EEM Spectrofluorometer

…whether single-walled carbon nanotubes, quantum dots, or nanocrystals. Optimised for detecting
nanomaterials near-IR fluorescence, the Nanolog modular EEM spectrofluorometer can help you determine their composition and structure. Based on the proven technology of the world-renowned Fluorolog® from HORIBA, the Nanolog is designed to give you a long life of reliable service and expert assistance.


  • Photomultiplier tubes, both thermoelectrically and liquid N2-cooled for UV through near-IR response out to 1750 nm
  • Solid-state photodiodes, for IR response to 2400 nm
  • CCD arrays for rapid acquisition and fast fluorescence Excitation Emission Matrix (EEM) fingerprinting
  • InGaAs arrays for rapid NIR acquisition and EEM fluorescence


Create your own customized Nanolog from a proven series of components to suit your needs. The Nanolog is a modular instrument, which means that you decide the arrangement of the basic building blocks to create your ideal spectrofluorometer for your experiments.
Choose the source, single- or double-grating excitation monochromator, sample compartment with a host of accessories, iHR320 emission spectrometer and optional second monochromator, and detector. No other company offers such a variety of instrument configurations tailored precisely for your experiment and budget.


The Nanolog is self-calibrating. Wavelengths and slits, accessories and sample turrets are all automatic, so you don’t have to worry about reproducible settings.
Our FluorEssence™ software is a powerful data acquisition package, further enhanced with Nanosizer™. Featuring our patented double-convolution integral algorithm specially designed for determining chirality and diameter of single walled carbon nanotubes, gives you the most advanced
nanomaterials system ever built.


No other company offers the wide variety of multi-channel detectors, sources, monochromators, and software to build an equivalent, powerful instrument. Who else can supply the applications support and service to get the full potential from your Nanolog? HORIBA Scientific has full applications laboratories in the USA, Europe, and Asia, plus affiliates and representatives the world
over. You can rest assured that you have the support you expect only from HORIBA.

Real nanomaterials performance

Single-walled carbon nanotubes come in a huge variety of structures and diameters. With a sample of these nanotubes, the Nanolog can run an excitation-emission matrix scan. With the finished scan, you transfer these parameters to our exclusive Nanosizer software, which automatically determines the chirality and diameter from the spectral landscape.
