Optics

Practitioners of Raman spectroscopy have struggled​​ with the elusive nature of Raman scattered “signal” photons from within the Rayleigh scattered source background. To extract this Raman signal from the background, highly wavelength-selective optical filters from​​ Iridian​​ are necessary to provide more signal with less background to the detectors to enable the visibility of molecularly unique Raman fingerprint characteristics.

An article reviews optical inspection and sensing systems, known as beam splitter microscope imaging systems, where the illumination is a laser source that is focused by the same objective used for imaging the surface.​​ The paper summarizes​​ the way diffractive beam splitters and beam shapers​​ are used in such systems and how to specify and integrate them in such setups.

Holo/Or is often approached by customers with such a setup requiring support in integrating diffractive beam splitters or beam shapers into the imaging system. This short article reviews the best way to do this for most typical cases.

Nd:YAG laser technology has become increasingly popular in a wide range of industries due to its remarkable capabilities and advantages.​​ An​​ article​​ from CRYSTECH​​ delves into the various benefits of Nd:YAG laser technology and how​​ it contributes to advancements​​ in electronic components, particularly in the realm of electronic materials and components, as well as piezoelectric crystal materials. From its superior laser properties to its versatility, Nd:YAG lasers offer significant advantages that make them indispensable in numerous applications.

Electronic components play a vital role in various industries, from telecommunications to consumer electronics. One of the key challenges faced by engineers and manufacturers is the generation of high​​ frequency signals. To overcome this hurdle, the use of neodymium-doped yttrium orthovanadate (Nd:YVO) has gained significant attention. An​​ article from CRYSTECH​​ explores how Nd:YVO4 enables high-frequency signal generation in electronic components and its impact on the industry.

Spectroscopy

A research team found that laser-induced breakdown spectroscopy (LIBS) is a promising technique for in situ measurement of hydrogen concentration in steel surfaces. The study compared LIBS to carrier gas hot extraction (CGHE).

The set-up used an Echelle spectrometer (Aryelle 200) from LTB Lasertechnik Berlin GmbH, which provided high spectral resolution (20-80 pm) simultaneously with a broad spectral range (200-800 nm).

Superlum announces that they have extended their 670-nm superluminescent diode (SLD) portfolio by adding one new part number to the list: S670.15.1. These SLDs have been developed specifically for applications where SLD spectrum width is more important than output power. Given a spectrum width of 15 nm, their coherence length (FWHM of coherence function) is estimated as less than 20 microns in the air. SLD modules​​ S670.15.1​​ are currently available in stock, ready for rapid, one-week shipment.
