New TG Series NIR Mini-Spectrometer Module from Hamamatsu

Hamamatsu has introduced a new spectrometer to the already highly popular series of transmission grating (TG) based mini-spectrometers.

All of these modules consist of a palm-top size polychromator integrated with optical elements, a photodiode array optimized for the required wavelength range, together with an image sensor driver circuit.

In addition, these spectrometer modules are supplied with sample software, which allows the user to set measurement conditions, acquire & save data and then display it graphically thus making it quick and easy to start taking basic measurements.

Use of the USB 2.0 interface means that no external power supply is required as the modules can use USB power from the PC and this, together with the compact design, allows for easy assembly into portable equipment.

The new C11482GA is an improved version of Hamamatsu’s existing NIR mini-spectrometer and uses a Hamamatsu InGaAs linear image sensor to cover the spectral region of 900nm to 1700nm.

Unlike Hamamatsu’s other NIR mini-spectrometers, the C11482GA does not use cooling yet still offers excellent low noise characteristics.

With a 7nm resolution, trigger compatibility and USB 2.0 connectivity, the C11482GA is ideal for applications such as water content measurement, component testing in the optical communications sector and film thickness measurements among many others.
