At Wasatch Photonics, we have deployed our extensive expertise in precision optics to the field of Raman spectroscopy. But what actually is it? Find out
Configuring 785 Raman for Your Application
Does your toolbox for 785 Raman have the versatility and sensitivity to take your application into new spaces? See how we bridge the worlds of compact and high-performance Raman with our flexible solutions in this tech note.
Spectroscopy: The Wasatch Advantage
We’ve designed our spectrometers to collect more light, keep more light, and detect more light. This results in much higher sensitivity, faster acquisition rates, and lower limit of detection. See the schematic and learn more.
Extending the Reach of Portable Spectroscopy
Reducing the size of your spectroscopy system doesn’t have to mean reducing its performance. In this tech note, we let our sensitivity, thermal stability, and reproducibility speak through the data. Ready to take the lid off? Read on.
Fluorescence: Lowering the limit of detection
Sensitivity is of paramount importance in a fluorescence measurement, yet how can you compare the relative sensitivity of fluorescence systems from different manufacturers? In this tech tip, we’ll define limit of detection (LOD), explain how to measure it yourself, and show you how the WP VIS spectrometer and cuvette accessory excels with picomolar level detection.

Why Wasatch for NIR
When was the last time you plotted an absorbance curve that was linear below 0.1 AU in the NIR? Learn the secrets behind our surprising performance in the NIR, and see how we can improve your measurements, from more sensitive Raman spectroscopy and absorbance to better thermal stability. See the data.
Why Wasatch for Raman
Too often, a Raman spectrometer’s data sheet doesn’t tell you what you really want to know. Is it sensitive enough? Does it produce clean spectra? Is it robust enough for OEM use? While every application is unique, we can share some benchmark data to show you how we outperform the competition, and why. See the data.
Raman: Wavelength Matters
The right excitation wavelength makes all the difference in Raman spectroscopy. Learn how to choose your Raman excitation wavelength based on Raman excitation efficiency, sample sensitivity, spectral range & resolution, and minimizing fluorescence background. Let’s get started.
Raman: How sample coupling affects data quality
Spectrometer or system? Probe or integrated laser? How you interface with your Raman sample depends not only on whether you value convenience or configurability, but also on the data quality you require. In this tech tip, we’ll show you how to get more out of our many sample coupling & configuration options. See the data, and how our probes outperform the rest.
