Over the years, dispersive Raman spectroscopy has increasingly been implemented for material identification thanks to its portability and sampling flexibility. When choosing a Raman instrument, one of the primary concerns is the wavelength of the laser that is integrated into the Raman spectrometer system. Even though the Raman shift of any material is only related to the material’s specific chemical structure and is independent of the excitation wavelength, different wavelengths have ...
Optotune’s focus tunable lens is suitable for 3D laser processing. In combination with galvo scanners or x-y tables, large scan volumes and small spot sizes can be achieved.
Flexible and fast focusing solutions with electrically tuneable lenses are highly beneficial for machine vision applications, such as quality control, packet sorting and barcode reading.
The purpose of this paper from Pacer is to give a brief overview of colorimetry. Colorimetry is the science of measuring colour and colour appearance. The main focus of colorimetry has been the development of methods for predicting perceptual matches on the basis of physical measurements. This topic is much too broad to be covered by one document, so a general coverage of the subject will be introduced.
Handheld Raman instruments such as the NanoRam from B&W Tek are well suited for pharmaceutical applications such as the testing of raw materials.
