Short-wave infrared cameras in semiconductor inspection applications

Several applications of SWIR (short-wave infrared) cameras in semiconductor inspection applications. Most of these applications rely on the capability of SWIR cameras to see through semiconductor materials such as silicon.

Choosing Dichroic Beamsplitters with Flatness/ RWE Appropriate to the Microscopy Method

Wavefront distortion can degrade image quality by reducing contrast or compromising resolution. In several microscopy applications, reducing wavefront distortion is critical to achieving the microscopy method.

Z-height measurement for scanning electron microscopes - Semiconductor case study

A Scanning Electron Microscope (SEM) is a type of microscope that produces images of a sample by scanning the surface with a focused beam of electrons.

Feel like you’re missing Raman signal – 405 nm can help see more

In recent years, Raman spectroscopy has attracted worldwide attention as an analytical technique applicable for a wide range of markets, from materials and life sciences applications to point of care analysis, industrial screening to pure R&D. Thanks to compact laser sources, high sensitivity cameras and ultra-light compact spectrometers, Raman systems in recent years have been further miniaturized with increased sensitivity while becoming multifunctional. In this application note, we show what performance improvements can be achieved by using a 405 nm laser compared to the longer wavelengths lasers used more conventionally.

Quantum Cascade Laser Spectral Histopathology: Breast Cancer Diagnostics Using High Throughput Chemical Imaging

   

Using a first-generation Spero QCL microscope, researchers at the University of Manchester accurately differentiated between four different malignant and non-malignant histological classes of an independent population set of 207 breast cancer patients. The study established that large tissue microarrays (TMAs) can be spectroscopically imaged within minutes instead of hours while achieving accurate disease segmentation using wide-field QCL imaging. This high-throughput, high-accuracy and label-free histological protocol could revolutionize histopathology by significantly reducing accurate diagnostic times and simplifying the pathology workflow.

Defects and Deformation of Boron Nitride Nanotubes Studied by Joint Nanoscale Mechanical and Infrared Near-Field Microscopy

   

Boron nitride nanotubes (BNNTs) are a one-dimensional material with interesting mechanical and physical properties. Researchers at the University of Toronto and Lehigh University used a Daylight Solutions MIRcat laser for infrared scattering near-field microscopy and nanomaterial characterization to study defects and deformations in the BNNTs and their impact on the mechanical properties.  These studies revealed that the BNNTs have polygonal facets, which implies that these nanotubes should have a range of reactive chemical and hyperbolic optical properties.

Real-time Breath Gas Analysis of CO and CO2 using an EC-QCL

   

Real-time breath analysis is a promising, non-invasive tool in medical diagnostics and has been used to study a variety of health biomarkers.  In this study, researchers at Umea University in Sweden investigated the physiology of CO as a biomarker for respiratory disease and oxidative stress using a Daylight Solutions mode-hop-free tunable laser.  Real-time detection using the laser was confirmed by comparison to expirograms measured by capnography.  It was found that eCO expirograms have a strong dependence on exhalation flow rate and breath-holding times.  This new sensor opens ways to study physiology and toxicology and may provide ways to distinguish between different endogenous and exogenous sources of eCO.

Bullseye® Apodizing Coatings and Filters

Bullseye® Apodizing Coatings and Filters

Wednesday, 24 May 2017

Bullseye® Apodizing filters are customizable density gradient filters that change radially from the center to the outside of the optical component. These filters are used to eliminate undesirable intensity variations in optical systems or to modify the wavefront of an optical source. Bullseye® filters come in two configurations, normal and inverse apodizing.
