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 […]

Saffron Quality: The price of authenticity

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 […]

Authentication of Pisco

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 […]

VPH Gratings: Flexibility in Design

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.

Tech Note: Long-range imaging – 800 nm OCT goes ultra-deep

  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 […]

Authentication of Turmeric with UV-VIS

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 […]
