Laser

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 and 830nm. 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.

CleanLaze®

Normalized Power (dB)

Laser lifetime of 10,000 hours ensures quality data for years to come!
 

Spectrometer

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 3cm can be achieved with our double pass transmission optics. Most Raman applications do not requir esuchtightre solution, 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.
   
Filter

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 175cm from the Rayleigh line. An E-grade filter upgrade is available, allowing the measurement of Raman peaks as close as 65cm-1 from the Rayleigh line.

   
Probe

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, 785nm, or 830nm.

Custom wavelength excitation probes available.

Detector

Cooled Detector for Low-Light Level Detection

Cooling an array detector with a built-in thermoelectric cooler (TEC) is an effective way to reduce dark current and noise to enhance the dynamic range and detection limit. The graphs below show the dark current and noise for an uncooled versus a cooled CCD detector at an integration time of 30 seconds. Operating at room temperature, the dark current nearly saturates the uncooled CCD. When the CCD is cooled to 10˚C, the dark current is reduced by four times. This allows the spectrometer to operate at long integration times and detect weak optical signals.
