Hamamatsu Photonics introduces the new InGaAs linear image sensor consisting of 512 pixels with a 25 µm pixel pitch. The G12230-512WB employs two InGaAs chips of different cut-off wavelengths, giving it a spectral response range of 950 to 2150 nm.
As each pixel from the InGaAs photodiode array is read in charge integration mode from the CMOS chip, this allows for high sensitivity and stable operation within a wide spectral response range.
The package is hermetically sealed providing excellent reliability. The device has two external conversion efficiency types which can be selected for your application from the signal processing circuit on the CMOS chip.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.

Measurements can be conducted using a Fourier-transform near infrared (FT-NIR) spectrometer, while there are also UV-Vis- NIR spectrophotometers that measure a broader spectrum of wavelengths.
