Request InfoLabsphere Inc.The UV-2000S manufactured by Labsphere Inc. is a UV transmittance analyzer designed to provide rapid measurement of the spectral transmittance of sunscreen products, particularly those with a sun protection factor (SPF) of 50 or higher. The benchtop instrument measures over a wavelength range of 280 to 410 nm. A dual-beam spectrometer with diffuse illumination produces accurate measurement of highly scattering samples, and filters are not needed to prevent sample overexposure. The software converts measurement data to provide the SPF, UVA to UVB ratio, critical wavelength, Boot’s star rating...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueDual-Comb SpectrometerThe IRis-C spectrometer from IRsweep utilizes dual-comb spectroscopy and quantum cascade laser frequency combs to offer a combination of high speed, high signal to noise ratio per time, as well as...Photonics Spectra September 2023 IssueHandheld NIR SpectrometerThe trinamiX PAL Two by trinamiX is a handheld NIR spectrometer designed for versatility, robustness, and convenience.
