Labsphere UV-2000F Fabric UPF Spectrophotometer

The UV-2000F provides literally instantaneous measurements. To those of you more used to old fashioned scanning monochromator-based instruments, prepare to be amazed! At its heart, the UV-2000F is a dedicated UV transmittance spectrophotometer that measures the diffuse transmittance (250-450nm) of a fabric sample. The Spectralon integrating sphere incorporates an optimised xenon flashlamp to provide diffuse illumination of the sample and minimise measurement integration time. New, high-performance diode array spectrometers coupled by advanced fibre optics are optimised at the system level for low stray light with superior wavelength stability and flash-to-flash repeatability. The use of a xenon flashlamp both minimises sample heating effects and promotes a greatly extended lamp life compared to instruments which employ a continuous xenon lamp. In addition, the UV-2000F emits no unpleasant ozone, unlike instruments which burn a xenon lamp continuously.

New & Improved

Many improvements are incorporated in to the UV-2000F to realise a new industry defacto standard for testing sun protective fabrics. System improvements include new spectrometers, a xenon flash lamp, improved optical coupling fibres, a new optical head positioning mechanism, a sample positioning stage and a new, robust software development platform. The new diode array spectrometers feature stable, concave diffractive optics for measurement integrity and repeatability, original holographic diffraction gratings (rather than replicated gratings) which are peaked for higher efficiency across the 280-400nm UV wavelength range, and longer pixel arrays for better pixel wavelength resolution. Illumination is now filtered at the integrating sphere to limit total exposure at the sample and to improve stray light performance. A higher flash rate reduces exposure times, minimising dark current and maximising dynamic range. Use of solarisation resistant fibres maintains high system throughput over time. Longer fibres filter higher order modes to provide cleaner grating illumination which in turn improves stray light performance.

Accurate UPF Results Even with Highly Absorbing Materials

The UV-2000F provides a minimum absorbance sensitivity of 2.7A at all wavelengths between 280 and 400nm. This helps to ensure that the UV-2000F can be relied upon to give accurate UPF results even with high protection factor materials.

Powerful Application Software

The UV-2000F software was developed within the Microsoft .NET Framework. The software includes modular architecture and supports the latest UI elements. The software supports the all current international test methods and is expandable to include new

industry or regional standards as they are published. The UV-2000F 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-2000F UV Transmittance Analyser.

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.

Education, Education, Education!

Never underestimate the importance that expert training will have on your ability to get the most out of your investment in a UV-2000F. Pro-Lite provides on-site installation and operator training in both the use of the UV-2000F and its software, available at additional cost.
