Astronomical Spectrographs

Wasatch Photonics VPH Gratings Look to the Stars Nightly, all over the world, observatories open their domes to collect light from the far reaches of the universe. The telescopes within diligently condense these precious photons for careful analysis by instruments like spectrographs, which further break down that light into its […]

Advantages of UV Raman

Exciting options for fluorescence suppression The trade off between signal strength and fluorescence background often dominates the choice of excitation wavelength for Raman spectroscopy. But what if fluorescence background could be eliminated entirely? UV Raman allows just that. In this application note, we’ll explore its advantages, the technical challenges it […]

OCTA Tutorial: How does OCT Angiography work?

Mouse ear, Cobra 800 OCT image

In this tutorial, we give a quick overview of OCT angiography – its emergence, advantages, and the technology. We also explore different methods employed in OCTA, as well as choice of scan pattern. OCT angiography (OCTA) refers to a class of medical imaging techniques that allows visualization of blood vessels […]

Implantable SERS Biosensors

Finding the right matrix for pH SERS-active sensing assays in conjunction with the availability of highly sensitive compact Raman spectrometers offer great promise for implantable biosensors. In this application note, we explore the potential of SERS to outshine fluorescence-based biosensors, looking at one research group’s innovative sensor design as they […]

NIR Grain Identification

Separating the wheat from the chaff with SIMCA Near-infrared (NIR) spectroscopy is routinely used to analyze grain identity and grain quality in agricultural production, and at various stages of processing. To work in these environments it must be rapid, consistent, capable of delivering robust answers, and preferably compact. To demonstrate […]

OCT in Ophthalmology

Expedition into the Eye >> Learn how OCT is transforming our understanding of the eye, from tear film to photoreceptors.   The eye is a delicate yet intricate structure, making it challenging territory to explore. With the emergence of optical coherence tomography (OCT) over the past 25 years, researchers and […]
