The UV-2000S rapidly measures the diffuse transmittance of sunscreen samples in the ultraviolet wavelength region from 250 – 450 nm. Labsphere’s Spectralon® integrating sphere incorporates a re-optimized xenon flash lamp to provide exceptional diffuse illumination of the product sample and minimize data integration time. New high performance diode array spectrometers coupled with new, advanced fiber optics are optimized at the system level for low stray light with superior wavelength stability and flash-to-flash repeatability.
Many improvements are incorporated in the UV-2000S to realize a new industry de-facto standard for in-vitro sun care product analysis. System improvements include new spectrometers, Xenon Flash Lamp, optical coupling fibers, optical head positioning mechanism, sample positioning stage and a new, robust software development platform.
The diode array spectrometers feature stable, custom concave diffractive optics for measurement integrity and repeatability, original holographic diffraction gratings, not replicated gratings, peaked for higher efficiency across the wavelength range, and longer pixel arrays for better pixel wavelength resolution.
Illumination is filtered at the integrating sphere to limit total exposure at the sample and to improve stray light performance. A higher flash rate reduces exposure time, minimizing dark current and maximizing dynamic range.
Use of solarization resistant fibers maintains high system throughput over time. Longer fibers filter high order modes to provide cleaner grating illumination improving stray light performance.
A built-in report function generates essential information at the click of a button. Reports include necessary information such as date, time, operator name, sample identification and test parameters. Reports are conveniently viewed on your PC, printed, or exported as text to data processing software for further review and analysis.
Developed with .NET Framework®, the license controlled UV-2000S Software features different in-vitro measurement methods for UVA/UVB protection factors of sunscreen including the COLIPA, Boots Star and FDA methods. By licensing the included software, users are able to receive free upgrades on their software for one year as new methods are released to the industry. This easy-to-use Windows® 7 and 10 compatible software facilitates capture/archival/retrieval and export of all data including bare substrate data that may impact UVA-PF due to surface roughness.
UV-2000S application software includes an integrated Performance Validation Routine that allows for on-site validation and re-validation to ensure optimum instrument performance. A set of calibrated standards, including a wavelength standard that captures six relevant spectral bands, is included with each UV Transmittance Analyzer.
The UV-2000S has replaced Labsphere’s UV-1000S as the industry’s choice for not only laboratory in-vitro SPF/UVA analysis, but also production floor quality control. New software has been released for the UV-2000S per the new ISO 24443 Sunscreen testing standards.
