BWS003 Comparisons of Other Products i-Spec™ series products are diffuse transmittance/ reflectance spectrophotometers with built-in integrating spheres and other accessory options for bench-top applications. The BWS 003 utilizes a TE cooled CCD array detector with wavelength coverage from 200-1050 nm. Designed for maximize sensitivity and dynamic range the i-Spec™ Q Yield is ideal for either high intensity or long illumination applications. A 16 bit high speed detection systems, enabling fast spectral capturing of 20 to >100 spectra per second thus making it ideal for spectrophotometric studies where high spectrum capture rate is essential. The spectrophotometers come with a USB 1.1/2.0 interface providing plugand-play computer connectivity. Windows based spectrophotometer operating software with OCX interface to major chemometrics software packages is provided. An integration sphere with high spectral reflectivity is an integral part of the sphere based models. The built-in reflectance sample holders and transmittance sample cells in sphere White reflectance reference standards options are available Features 250-1000 nm UV-NIR sphere based model USB 2.0/1.1 plug-and-play interface Built-in PTFE integration sphere No moving parts TE cooled/regulated for long term stability Built-in sample holders Applications Agricultural, pharmaceutical, and petrochemical Surface Studies Material spectral diffuse property characterizations Opaque chemical solution analysis Specifications Principle - Single beam integrating sphere, light source stabilized, NIR transmittance/ absorbance/ reflectance Spectrophotometer with USB interface, operated by personal computer with associated programs installed.
