Plastic waste is a growing issue in this enclosed ecosystem we call Earth. As landfills grow, we must forgo our single-use mentality and embrace recycling to create a more responsible plastic economy. Identification of plastic types for separation is key to effective recycling, and Raman spectroscopy offers the speed and […]
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 […]
Up to 3% of the population in both Europe and North America suffer from gout, a common form of inflammatory arthritis that results in intensely painful bouts of joint swelling, warmth, and redness. Caused by buildup of monosodium urate crystals in the joint space, a gout attack can last for […]
Spectroscopy has come into its own over the last decade, making the leap from lab to industry and the field with handheld and field-portable analysis systems. As with many technologies, however, the reduction in size has often meant a compromise in performance as compared to traditional benchtop Raman systems. At […]
The greatest challenge in compact NIR spectroscopy is collecting enough signal to achieve adequate SNR (signal to noise ratio). With many spectrometers on the market, it’s hard to know which has the performance needed. Here, we benchmark the superior sensitivity, data quality, and reliability of our NIR spectrometers. InGaAs […]
How spectra came to probe the depths – the origin of OCT 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 […]
