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 […]
Raman spectroscopy beyond the fingerprint region proves ideal for polymer identification in high throughput sorting of plastics, discriminating within families & signaling the presence of additives.
UV-VIS absorbance guarantees freshness, flavor Saffron is the most expensive spice in the world, commanding $20 for a single gram of premium grade Kashmiri or Spanish saffron, and easily $5000/kg in bulk. These precious deep red threads lend dishes a subtle but luxurious fragrance, flavor, and bright golden color. The […]
From origin to alcohol content with Raman spectroscopy Validating authenticity, purity, alcohol content, and safety are common problems in the lucrative alcoholic beverage market, particularly when pricing is dependent on origin, variety, or alcohol content. The industry relies heavily on expert tasters and time-consuming analytical laboratory testing to combat substitution […]
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 […]
Spices such as turmeric are one of the most commonly adulterated foods. Their high value makes even a small dilution with fillers financially worthwhile, and when sold in ground form, easy to disguise. Spectroscopy offers the potential to provide testing of spices in the field at reasonable cost, reducing the […]
A new portable 785 Raman instrument puts accurate, objective testing for the crystals causing specific arthritic conditions like gout within reach for more clinics, with less sample prep.
