Introduction Reflectometry is a non-destructive, non-contact way to measure the thickness of films using light. It works on the principal of optical interference between the light rays reflected from each interface in a layered structure. The same phenomenon that gives soap bubbles th
The Abstract: Spectral measurements to 153 nm can be achieved easily and economically with the high-sensitivity Maya2000 Pro with Extra-Deep-UV Option. Nitrogen purging of the spectrometer helps to mitigate water and oxygen absorption in the vacuum ultraviolet.Introduction: A variety
Application material and images provided by dr K. Jalink, the Netherlands Cancer Institute, Amsterdam Microscopic and micro-spectroscopic techniques have become powerful tools to aid fundamental cancer research. We study the basic unit of life: the cell. Until a few decades ago, cells
Plastic tubing is available in a variety of opacities ranging from clear to translucent. The transparency of plastic tubing is varied for a number of reasons including providing contrast for visual monitoring of fluid flow, decreasing exposure to ambient light and making the tubing mo
Reflectance spectroscopy is a versatile technique than can be used to identify and characterize a range of powdered samples including mineral powders, grains in lunar samples, mining samples, natural deposits, soils and sediment core samples. In this application note, reflectance spec
Cutting tools generate heat and friction during the machining process. To improve the speed of machining and reduce tool wear, the cutting tool is bathed with cutting fluids that cool and lubricate the tool and machined part during use. While these cutting fluids are critical to the m
Near Infrared (NIR) spectroscopy is used for a range of applications from determining the quality of agricultural products to studying the composition of newly formed stars in space. When combined with multivariate calibration techniques, NIR is a powerful analytical tool. A single NI
In the 85 years since the Raman effect was first observed, a number of key advances have catapulted Raman spectroscopy to a position as the preferred technique for chemical identification across a broad range of application areas. With no interference from water, little to no sample
Reflectance is the fraction of light reflected from a surface as a function of wavelength. When properly measured, reflectance tells us about the color of an object and its texture — and even hints at the material from which it is made, since the light that is not reflected is e
Abstract Black coatings are applied to a surface to minimize the reflection of light from the surface. In the case of an optical bench, the mechanical housing is painted black to reduce stray light in the spectrometer. With a range of black coatings available with varying reflectivit
