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 […]
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 […]
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 […]
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 […]
High speed UHR-OCT reaches the cellular level by Cicely Rathmell Recent increases in the speed and resolution of ultrahigh resolution OCT are opening up new possibilities for in-vivo, non-contact imaging of the cellular structure of biological tissue at image acquisition rates high enough to suppress significantly image artifacts arising from […]
Raman shows its strengths for process monitoring in biotechnology as we use PLS and PCA to follow the fermentation of glucose by yeast to generate ethanol with a probe-based 785 Raman system.
Our toolbox for Raman spectroscopy gives you the flexibility to optimize your application without compromising on performance or size. Explore the many options!
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 […]
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 […]
OCT as Optical Biopsy in Dermatology Skin is the largest organ of the body, possessing an amazing ability to heal itself even after considerable damage. As our primary barrier against microbes and the elements, it is key that we understand the dermal repair process and how to speed it. OCT […]
