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 […]
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 […]
Wasatch Photonics VPH gratings offer optical and instrument designers a tremendous amount of flexibility to optimize performance for a specific application. In this tech note, we’ll discuss the benefits of the various standard and patented grating design technologies at our disposal, and the general grating parameters we can control to meet your specific needs.
OCT imaging has traditionally required the use of longer wavelengths to probe depths greater than a few millimeters in a single scan, bringing with it the higher cost associated with NIR detectors. Not to be deterred, we have developed a patent-pending optical spectrometer design that allows us to achieve […]
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 […]
