Characterizing Microplastics with Raman Spectroscopy
As the need to manage plastic waste increases, researchers are using Raman spectroscopy to characterize the toxicity of polymers and identify their sources. Several technologies exist for characterizing microplastics, including pyrolysis gas chromatography/mass spectrometry, Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy.

MIR Laser Spectrum Analyzer
The 772B-MIR Laser Spectrum Analyzer from Bristol Instruments combines proven Michelson interferometer technology with fast Fourier transform analysis to characterize the spectral properties of lasers that operate from 1 to 12 μm. It is the ideal solution for scientists and engineers who need to know the spectral properties of their pulsed mid-IR lasers.

Lidar: A Technology at Use in Daily Life
Lidars provide point cloud distribution — to represent the 3D environment — using the backscattering of a laser beam from the target surface. They have long been used for purposes of mapping and atmospheric sensing. Lidar is no longer a technology to consider for the future; it is becoming part of our daily lives.

IR Metrology with Visible Light
A new approach to IR metrology uses common optical components for the visible range. The technique is based on nonlinear interference of correlated photons, in which information about the photon in the IR range is inferred from the measurement of its correlated photon in the visible range.

Artificial Intelligence in Particle Image Velocimetry
The first article to use the term “particle image velocimetry” (PIV) was published in 1984. Since then, PIV has become a standard method for flow measurements. Continuous lasers or special double-pulse lasers, also known as PIV lasers, are used to generate laser light sheets with special optics.
