Laboratory Raman Fiber Spectrometer: i-Raman EX

The i-Raman^® EX spectrometer is part of B&W Tek’s award-winning range of i-Raman laboratoryRaman systems and features a 1064-nm version of the company’s patented CleanLaze^® excitation laser.

The laboratoryRaman spectrometer uses a high-sensitivity InGaAs array detector with a high dynamic range and deep TE coolingand also features a high-throughput spectrograph design, thus delivering an excellent signal-to-noise ratio without causing autofluorescence. Thanks to these features, users can quantify an array of natural products, colored samplesand biological samples, like cell cultures.

The i-Raman EX spectrometer offers a spectral coverage range between 100 and 2500 cm⁻¹, enabling users to quantify the whole fingerprint area. The spectrometer has a lightweight design, a small footprintand consumes only minimal power, offering research-grade Raman capabilities anywhere.

The i-Raman EX spectrometer is supplied with an XYZ-positioning-stage probe holder and a fiber-optic probe. It can be utilized with many different sampling accessories to enable the measurements of different kinds of samples. The spectrometer can also be used with B&W Tek’s proprietary BWIQ^® multivariate analysis software or with BWID^® identification software.

With the i-Raman EX spectrometer, users can easily achieve a high-precision quantitative and qualitative Raman solution without fluorescence.
