Handheld Spectrometer by Sudan Instruments

Our patented optical head is just a few millimeters in size, providing sensitivity and accuracy comparable to top bench spectrometers. With low power consumption and zero warm-up time, it performs hundreds of scans on a small rechargeable battery. Handheld Raman spectrometers combine the long-established principles of Raman spectroscopy with miniaturized components, enabling users to take and use these handy devices anywhere. Like any Raman spectrometer, they use laser light to illuminate a sample, generating Raman photons that are used to. This present review article considers the rapid development of miniaturized handheld near-infrared spectrometers over the last decade and provides an ove...
