High Absorbance Scanning with the PerkinElmer LAMBDA 850 UV/Vis and LAMBDA 950/1050 UV/Vis/NIR Spectrophotometers
15 Dec 2014In materials research there is sometimes a need to scan high absorbance samples such as laser protection lenses, optical filters, and polarization materials. Such sample types often need to be measured across the whole UV, Vis, and NIR ranges of the electromagnetic spectrum. This application note describes the procedure for high absorbance scanning with the reference grade PerkinElmer LAMBDA™ 850 UV/Vis and LAMBDA 950/1050 UV/Vis/NIR double monochromator spectrophotometers.

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.
