NIRS: A Quick And Easy Way To Detect Allergens

A University of Illinois study used near-infrared spectroscopy to detect allergens in quinoa flour. The method is highly accurate, and researchers say it will not be difficult to develop low-cost miniature sensors based on their methodology.

SPOTLIGHT ON SPECTROSCOPY

Improving The Future Of Smart Agriculture With Spectroscopy

Climate change and population growth have increased demand for food, but unpredictable weather patterns can cause crop failures, forcing farms to do more with less.

Using SWIR Spectroscopy For Light Investigation And Analysis

NIR fluorescence spectroscopy is a powerful tool for material analysis. It can identify organic matter, fungal biomass, and map nitrous oxide (NO) concentrations in vivo.

How To Integrate OEM/ODM In Spectroscopic Devices

OEM/ODM services are ideal for organizations that require optics, spectroscopy, and/or photonics-related products and subsystems.

Using IR Spectroscopy For Counterfeit Drug Detection

Spectroscopy technology utilizes diamond-turned mirrors, beamsplitters, and other optical components to detect harmful chemical compounds in counterfeit opioids and pharmaceutical drugs.

How Custom Raman Edge Pass And Dichroic Filters Optimize Performance

Different Raman devices have different optical filtration needs as well as competing technical demands.

INDUSTRY INSIGHTS

Improving The Sensitivity Of Multicolor Microscopy Techniques

Single molecule fluorescence (or Förstner) resonance energy transfer (smFRET) is used to measure distances at the 1-10 nanometer scale in single molecules, typically biomolecules.

Space & Spectroscopy: Shedding Light On G&H’s Laser Tuning Capabilities

Space is perhaps no longer "the final frontier," but as an operating environment for optical components, it remains the ultimate test of the technology’s reliability, resilience, and precision.

What Are The Limitations Of My Laser Power Meter’s Damage Threshold, And How Can I Avoid Exceeding It?

Excessive power, average power duration, power density, pulse width, and wavelength absorptivity can all damage laser power meters, requiring careful usage and consideration of these factors.

Narrow Linewidth Lasers For Brillouin Light Scattering Spectroscopy

As magnetic materials gain increased importance for information technology, Brillouin light scattering spectroscopy (BLS) is the perfect technique to investigate the magnetic properties of such materials.
