Highly Sensitive, High Resolution Fiber Optic Raman System
The i-Raman® Plus is part of our award winning line of i-Raman portable Raman spectrometers powered by our innovative smart spectrometer technology. Using a high quantum efficiency CCD array detector with deeper cooling and high dynamic range, this portable Raman spectrometer delivers an improved signal to noise ratio for up to 30 minutes, making it possible to measure weak Raman signals. The i-Raman Plus features the unique combination of wide spectral coverage and high resolution with configurations measuring from 65 cm-1 to up to 4200 cm-1, enabling you to measure stretching bands around 3100 cm-1. The system’s small footprint, lightweight design, and low power consumption provide research grade Raman capabilities anywhere. The i-Raman Plus comes standard with a fiber optic probe, and can be used with a cuvette holder, a video microscope, an XYZ positioning stage probe holder and our proprietary BWIQ® multivariate analysis software and BWID® identification software. With the i-Raman Plus, a high precision qualitative and quantitative Raman solution is at your fingertips.

Creating Raman Scatter
In Raman spectroscopy, it is essential to utilize a clean, narrow bandwidth laser due to the fact that the quality of the Raman peaks are directly affected by the sharpness and stability of the delivered light source. The i-Raman® spectrometer system features a patented CleanLaze® technology with a linewidth < 0.3nm when equipped with our 785nm laser. This technology results in the correct center wavelength and avoids the phenomenon of “mode hopping.” In addition, the laser output power can be adjusted in the software from 0 - 100%, allowing you to maximize the signal-to-noise ratio and minimize integration time.
Laser lifetime of 10,000 hours ensures quality data for years to come!
Collects Data within 175cm-1 of the Rayleigh Line
The center wavelength of the laser line is precisely maintained even when the peak power is increased by utilizing a series of high end filters. A laser line filter is used to clean up any side bands and ensure a narrow excitation is delivered to the sample by removing all secondary excitation lines before exciting the sample. The light collected from the sample is then filtered via a notch filter. Finally, an ultra steep long pass filter further removes lingering laser lines to allow accurate measurement of Raman peaks as close as 175 cm-1 from the Rayleigh line. An E-grade filter upgrade is available, allowing the measurement of Raman peaks as close as 65 cm-1 from the Rayleigh line.
Optimized for Raman Spectroscopy
The spectrometer design in the i-Raman is dedicated for Raman applications. You can customize your spectrometer by choosing from a variety of excitation wavelengths. In addition, each configuration can be further customized for your individual detection needs. Choose from wider spectral range or high resolution optimized systems. Research grade spectral resolution of 3 cm-1 can be achieved with our double pass transmission optics. Most Raman applications do not require such tight resolution, so a wider spectral range would be the better choice in that case. The high-throughput optical layout of all i-Raman configurations are ideal for those low-light level Raman applications.
Easy Transition Between Sample Types
The probe allows for measurement of various materials in the form of liquids, gels, powders, or solids under both lab conditions (lab grade) or demanding environmental conditions (industrial grade). Constructed with state-of-the-art telecom packaging techniques, the probe has a flexible fiber coupling encased in a durable protective jacketing material which delivers Rayleigh scatter rejection as high as 10 photons per billion. Wavelength excitation probes come in 532nm and 785nm.
