Extending Raman’s Reach

Bridging the gap illustration

Learn how a reduction in spectrometer size need not mean a compromise in performance as compared to traditional benchtop Raman systems, thus expanding the possible applications served by Raman.


Optimizing OCT Spectrometer Performance


Key design factors & buy vs. build performance Ask anyone in optics how a spectrometer works and they can tell you – it separates a beam of light into its constituent colors or wavelengths for qualitative or quantitative analysis of the incoming light’s spectral composition. Spectrometers are widely used for […]

Tech Note: Raman Sample Coupling

Raman spectroscopy involves delivery of a high intensity of laser light to a very small focus, while simultaneously requiring sensitive detection of less than one-millionth the number of scattered photons. How that light is delivered to and collected from the sample has a significant impact in the quality of data […]


LAMOST Telescope, National Astronomical Observatories, China


Mapping the Milky Way and Beyond >> The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) was designed to conduct a 5-year spectroscopic survey of 10 million Milky Way stars, as well as millions of galaxies. It is a quasi-meridian reflecting Schmidt telescope located in Xinglong Station of the National […]

Richard Rallison

During the 70’s, Richard Rallison formed a company called “Electric Umbrella”. He made hologram apothecary jars and hologram glass discs that were used as key, chains, pendants and other forms of jewelry. He was a holography pioneer and successful. Electric Umbrella was a profitable and provided and income for Richard […]

Ultimate Diffraction Grating

Holograms are a novel way to optically manipulate light. In the early 70’s, Richard Rallison developed a process for making holograms using Dichromated gelatin (DCG). From this, he formed a company to produce various holographic images on 2″ glass disks. He was successful at this and became well known as a holography […]

World’s Fastest Spectrometers

80 years of volume phase holographic experience came together to form Wasatch Photonics (WP). From this, we developed “Ultimate Diffraction Gratings”. Spectroscopy was a natural extension of our grating business, so we opened our Durham facility to incorporate our gratings with an optimum optical design. This f 1.3 optical design paired […]

Getting All the Photons

The invention of the laser, in 60’s, made real 3D holograms a reality. Holography was born in an era of science, rock and roll, hippies and art. The scientific development and the extreme 3D Imagery produced was exciting and sometimes intoxicating. Richard Rallison made his first hologram, in his kitchen, […]
