WebHow does an Optical Spectrometer work? The goal of any optical spectrometer is to measure the interaction (absorption, reflection, scattering) of electromagnetic radiation with a sample or the emission (fluorescence, phosphorescence, electroluminescence) of electromagnetic radiation from a sample. WebOver a short period of time, the spectrometer automatically scans all the component wavelengths in the manner described. The ultraviolet (UV) region scanned is normally …

WebFor UV-VIS and NIR range spectroscopic applications, xenon is a popular light source choice, but most spectrometers use a halogen lamp. Xenon offers smooth emission for UV-VIS spectrums ranging from 750-1000 nm, but halogen lamps are more affordable. When a continuous UV spectrum is required, a deuterium arc lamp is the optimal light source. WebThe Cary 60 UV-Vis spectrophotometer has a wavelength range of 190–1100 nm that can be scanned in under three seconds. Our versatile UV-Vis spectrophotometer can be fitted with long pathlength cuvettes and solid sample transmission or reflectance accessories, and is ideal for remote UV-Vis absorbance analysis, when fitted with fiber optic probes.

WebFor UV-Vis detection, chromatographers can choose between three types of detectors: a variable wavelength detector (VWD), diode array detector (DAD), or multiple wavelength detector (MWD). In variable wavelength detection, a single chosen wavelength from the UV-Vis spectrum illuminates the sample.
