MODULE Mini-spectrometer TG series C9404MC, C9405MC Integrating optical system, image sensor and circuit HAMAMATSU TG series mini-spectrometers are polychromators integrated with optical elements and an image sensor. Light to be measured is guided into the entrance port of TG series through an optical fiber and the spectrum measured with the built-in image sensor is output from the USB port to a PC for data acquisition. C9404MC and C9405MC are palmtop-size units and operate on USB bus power. Two models are available to cover different spectral ranges: C9404MC (TG-UV-MOS) and C9405MC (TG-SWNIR-MOS). The TG series comes with sample software, device driver and DLL that let you easily set measurement conditions and acquire, save and graphically display the spectrum data. Features Applications C9404MC (TG-UV-MOS) l High throughput due to transmission grating made of quartz l Highly accurate optical characteristics l Fluorescence measurement l Tooth decay analysis l No external power supply required: Uses USB bus power l UV light source testing l Compact design for easy assembly C9405MC (TG-SWNIR-MOS) l Wavelength conversion factor *1 is recorded in internal l Detection of saccharic acids in foods memory l Taste analyzers l LED testing *1: A conversion factor for converting the image sensor pixel number into a wavelength is recorded in the module.

FOCUSING LENS TRANSMISSION GRATING ■ Connection example (transmission light measurement) Light to be measured is guided into the entrance port of TG series through an optical fiber and the spectrum measured with the built-in image sensor is output through the USB port to a PC for data acquisition. There are no moving parts inside the unit so stable measurements are obtained at all times. An optical fiber that guides light input from external sources allows a flexible measurement setup.
