Raman spectrometer RamSpec

BaySpec's RamSpec series NIR long-wave Raman Systems are designed to meet real-world challenges for best-in-class performance, long-term reliability, compact size and ultra-low fluorescence interference for Raman instrumentation of biological samples such as tissue and skin. Benefiting from experience manufacturing high-volume spectral monitoring devices for the telecommunications industry, BaySpec's NIR spectral devices utilize low-cost field proven components. For the first time in instrumentation history an affordable, accurate and ruggedized Raman spectral engine is a reality.
The RamSpec Series employs a highly efficient Volume Phase Grating (VPG) as the spectral dispersion element and an ultra sensitive InGaAs array detector as the detection element, thereby providing high-speed parallel processing and continuous spectrum measurements. As an input, the device uses a fiber optic bundle or slit optics arrangement based on customer preferences. The signal is spectrally dispersed with the VPG and the diffracted light is focused onto an InGaAs array detector. The control electronics read out the processed digital signal to extract required information. Both the raw data and the processed data are available to the end user.

There are a soft cooled version for 532 nm and 785 nm and a deep cooled version for 785 nm and 1064 nm for exellent signal/noise ratio over wide operating ranges.
