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 […]

Wound healing & OCT

Wound Healing & OCT

Wound healing & OCT

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 […]

Plastics recycling

Rapid Plastic ID with Extended Range Raman

Plastics recycling

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 […]

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 […]

Gout detection with POCRS - composite image

Diagnosing Gout at Point-of-Care with Raman Spectroscopy

Gout detection with POCRS - composite image

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 […]

Tech Note: Extending the Reach of Portable Spectroscopy

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 […]
