MATERIALS, COATINGS WHITE PAPERS
Raman SpectroscopyTo achieve accurate and precise Raman measurements, optical filters play a crucial role in enhancing signal-to-noise ratio, and reducing background interference. This white paper explores the fundamentals of optical filters, their types, and their indispensable role in Raman spectroscopy applications. It will also discuss the importance of selecting appropriate optical filters to optimize Raman spectroscopy experiments and enhance the overall analytical performance.
Multiband Optical Filters Are Telecom Networks' MultitaskersThe ability to combine more than one spectral band into a single optical filter can enable flexibility of system design and reduce the number of components and the costs needed to achieve a desired functionality in fiber optic telecom components....

Surface Characterization of Tribological Coatings: Wear Properties, Thickness and RoughnessWith the S mart 3D profilometer, it is possible to more precisely measure the volume loss of the wear tracks after the friction and wear tests, since it measures the real shape of the wear track. There are many parameters that are important to study...
Applying Durable Optical Coatings to Flexible SubstratesGone are the days of designing a system exclusively around traditional, flat, and rigid optical shapes. Advances in optical coatings and coating processes enable optical design engineers to test the limits of coated, curved, and unusual shapes...
Measuring Absorptance and Refractive Index of Thin Films with UV/Vis/NIRAn optical coating consists of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties for an optical system. In this paper we will show how the absorptance, refractive index, and film...
Are You Facing any Problems Securing Optical Parts?You need just a couple of pieces for trial. You need to achieve an exact specification. You need to keep the same quality in every order. You cannot find the best fit material for your design. You always need the material certificate. You need to...
