IndiGo NIR

Grating based spectral sensors covering 720 to 1050 nm with 2 nm resolution (FWHM).

Trinamix

Scanspectrum

The ScanSpectrum is a handheld and mobile phone operated grating spectrometer that covers the wavelength range 400-1000 nm. It can be used for both reflectance and transmittance spectroscopy. An android operated smartphone is connected using a usb-cable and used for edge computing and graphical user interface.
