Spotlight On Raman Spectroscopy
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.

Raman Spectroscopy Enhanced By A Back-Illuminated sCMOS Camera

Operating in a climate-controlled lab or on the Martian surface, back-illuminated sCMOS detectors provide high sensitivity, high dynamic range, and low noise, even in in low-light conditions.

Improving The Future Of Smart Agriculture With Spectroscopy

Climate change and population expansion have a direct impact on agriculture, which has led to an increased number of people needing to be fed. However, due to changing weather patterns causing complete crops to fail, farms are forced to produce more with less.

Breeze — A Safer and Faster Way For Illicit Drug Detection

Everywhere first responders operate, they risk exposure to substances such as fentanyl and synthetic cannabinoids to phosphorous and other chemicals. BaySpec’s Breeze Smart Palm Spectrometer provides first responders a viable handheld solution to quickly identify unknown substances.

Advanced Mask Printability Analysis Using TINT Virtual Stepper System

In this case study, Zygo Advanced Imaging Group's TINT Virtual Stepper Defect Analysis System's ability to predict CD printability of various known features on photomasks is tested. The validation of this tool will help keep both mask makers and wafer makers on schedule.

Essential Laser Beam Parameters To Know About Your Laser System

The essential laser beam parameters include beam profile such as Gaussian, flat-top or irregular, beam size, wavelength, and laser type.

Pockels Cells Application Note

G&H manufactures a comprehensive range of Pockels cells for applications in wavelengths from the UV to the IR. Pockels cells are used in a variety of applications benefitting from rapid/dynamic polarization control, Q-switching, light intensity control, intensity, modulation, dynamic waveplate, and more. 

Optical Filters For Raman Analysis: Finding The Needle In The Haystack

Most Raman microscopy applications seek to maximize access to the Raman fingerprint of the molecule of interest, requiring filters that provide “more signal with less background.” This article discusses optical filters for Raman analysis, addressing filters for both bench-top and portable Raman applications.

Precision Optics For Military Applications

This application note reviews a number of precision optics suitable for military applications, including corner cube retro-reflectors, integrator rods, mirrors, windows, and cube beamsplitters, as well as a wide variety of prisms.
