Partnership yields portable, long-wavelength Raman spectroscopy for biomedical apps

NOVEMBER 5, 2008 -- Biomedical and analytical instruments has long had need for long-wavelength excitation Raman spectroscopic capabilities for lab, hospital bedside, and portable field work. Now BaySpec Inc. (Fremont, CA) and Andor Technology (Belfast, Northern Ireland) say their collaboration has yielded a solution to meet this need.

The partners say their new technology enables up to three times greater collection efficiency than standard Czerny-Turner spectrographs. Excitation wavelengths beyond the typical 785 nm or 810 nm in dispersive technology-based Raman instruments have been unavailable; the Andor-BaySpec collaboration has generated 1064 nm capability.

The resulting instrument, the Nunavut NIR 1064nm Long-wavelength Dispersive Spectrograph, promises flourescent-free spectral measurements. BaySpec CEO William Yang says it will have particular application across the biomedical market. "The price-performance of this system has generated great interest," he adds

Based on Andor's iDus InGaAs detector array camera and BaySpec's high throughput Volume Phase Gratings (VPG) spectrograph, the instrument boasts thermo-electric (TE) detector cooling down to -85ºC, USB2.0 plug and play connectivity, F/1.8 aperture and spectral resolution of 8 cm-1 alongside with 3000 cm-1 spectral coverage.

Antoine Varagnat, Market Development Manager within Andor Technology, said, the offering will "make 1064nm Raman even more powerful and accessible to the research community and the industry."

BaySpec will demonstrate the unit at Pittcon 2009 (March 8-13, Chicago).
