Company Description
Wasatch Photonics creates products that redefine the limits of compact spectroscopy. We're fascinated by the many ways light can be used to understand nature and solve the problems that touch our lives each day. Our products expand the boundaries of what diode-array spectrometers can do (not your budget)-delivering 10x more signal, lower limit of detection, and faster measurements in a compact footprint. Every aspect of our spectrometer designs has been optimized to maximize throughput and minimize noise, from low f/# inputs to near diffraction-limited transmissive optics and our own patented broadband, high efficiency gratings. Whether for research, field use, or OEM integration, we can develop a system perfectly tuned to your application.

Major Products/Services
Raman: Clearer, faster spectra at more excitation wavelengths than anywhere else: 405, 532, 638, 785, 830, & 1064 nm.
NIR: Superior sensitivity and SNR for rapid measurements, 900–2500 nm. Superb thermal stability and linear absorbance below 0.1 AU.
Fluorescence: Picomolar limit of detection for benchtop fluorimeter sensitivity in a fraction of the footprint.
VIS-NIR: High efficiency and low stray light from 400–1100 nm, ideal for low light applications, kinetics monitoring, and high-throughput quality control.
Full Configurability: All products offered as fiber coupled/free-space spectrometers or integrated systems; choice of slit size and detector cooling. Custom gratings available upon request for OEMs.

X-ray analytical techniques, spanning X-ray fluorescence (XRF), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), are becoming faster, more portable, and more energy-efficient, with microbeam XRF spot sizes once exclusive to synchrotrons now available on laboratory benchtops.
Jürgen Popp, winner of this year’s Ellis R. Lippincott Award, discusses the regulatory, cost, and workflow hurdles of moving Raman spectroscopy into hospitals.
A recent conversation with Kevin Wilkinson, a professor of environmental chemistry at the Université de Montréal, sheds light on why no single signature can separate engineered nanoparticles from natural ones.
Top articles include the publication of a new terminology guide focused on data processing, machine learning, artificial intelligence (AI), and chemometrics.
This column shows that a Raman plate reader paired with partial least squares regression can simultaneously quantify glucose, fructose, sucrose, and ethanol in yeast fermentation samples, using turbidity-matched calibration standards to correct for yeast-induced turbidity, and offers a rapid, label-free, high-throughput method for tracking sugar consumption and ethanol production in strain screening, media optimization, and process development.
This column, the second installment on highly substituted benzene rings, shows that tri- and tetra-substituted substitution patterns can be distinguished by whether the ring bending peak is present and by the position of the in-phase aryl C-H wagging peak, which shifts according to how many adjacent hydrogens the ring carries.
How do ions and water interact at the atomic level in nanochannels grafted with polymer brushes using all-atom molecular dynamics simulations? Siddhartha Das of the University of Maryland and his team are working on answering this question.
