Sol HT Series 1064 nm Raman Spectrometer

By B&W Tek

Do More with Higher Throughput The Sol HT spectrometer has been optimized to move as many photons to the detector as possible. This means the Sol HT series is perfect for a low-light application such as Raman Spectroscopy. The overall sensitivity allows for more free use of the detector's High Dynamic range modes to achieve better SNR and shorter scan times without sacrificing overall signal intensity. Smooth Operation From a High Quality 512 pixel Detector The Sol HT is field tested in our i-Raman series Laboratory Raman instruments to ensure performance is robust and reliable. The detector has several gain modes to meet dynamic requirements. The High Dynamic Range detector mode will drop the noise and overall gain to improve the short integration time scans, while the High Sensitivity detector mode will improve the signal intensity while sacrificing the noise floor. Thanks to the fluorescence suppressing nature of 1064nm Raman, the Sol HT is equipped to tackle the challenging samples. The Sol HT series uses a high quality extended InGaAs spectrometer for the widest NIR range possible. Improving Cooling for Long Acquisition Times Deep cooling is an integral part of achieving high-quality spectra using InGaAs arrays. The Sol HT is equipped with a multi-stage TE Cooling package to cool down to -15° C which suppresses dark noise and improves overall instrument stability. Long acquisition times can be performed without the worry of overwhelming dark current. FC / PC Fiber Optic Input FC/PC fiber optic connection is the default input method for Sol HT. Unlike SMA905, FC/PC allows for more repeatable fiber insertions. The spectrometer pairs perfectly with the variety of Laboratory Raman probes available from Metrohm Spectro, allowing for flexible sampling to meet the sample anywhere.
