BaySpec Inc. has released the f/1.8 series SuperGamut near-infrared spectral engines. They feature ultrahigh throughput, have no moving parts and provide rugged performance suitable for applications in process automation technology; petrochemical facilities; pharmaceuticals; food processing; agricultural feed, semiconductor wafer, pulp and paper monitoring; breweries; cosmetics; counterfeit goods detection; water quality; and medical diagnostics. The series employs an efficient volume phase grating (VPG) as the spectral dispersion element, customizable to any wavelength range, and an ultrasensitive InGaAs array detector as the detection element, providing high-speed parallel processing and continuous spectrum measurements. The devices use a fiber optic input or slit optics arrangement, based on customer preference. The signal is spectrally dispersed with the VPG, and the diffracted field is focused onto the InGaAs array detector.
