Request InfoLabsphere Inc.The UV-2000S UV transmittance analyzer from Labsphere Inc. provides greater dynamic range and functionality over the predecessor model. Designed to measure the spectral transmittance of sunscreen products, especially those with a sun protective factor (SPF) of 50 and higher, the benchtop instrument measures the diffuse transmittance of a product sample over the 280- to 410-nm- wavelength range. A dual-beam spectrometer with diffuse illumination accurately measures highly scattering samples. No filters are needed. The application software converts measurement data to provide the SPF, UVA to...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 5/17/2022Biomolecular Characterization DeviceThe Apollo biomolecular characterization device from RedShift BioAnalytics Inc. uses microfluidic modulation spectroscopy (MMS) technology to provide sensitive, precise measurements of biomolecule...BioPhotonics Mar/Apr 2024 IssueSpectroscopy ModuletrinamiX in collaboration with LUMILEDS and VIAVI has developed a miniaturized spectroscopy module that can be integrated into a smartphone.
