Hamamatsu Photonics Unveils New C11118GA Near-Infrared Spectrometer

Hamamatsu Photonics has added a new long-wavelength spectrometer to its TG series.

The C11118GA near-infrared spectrometer functions in the 0.9-2.55 µm waveband and has a low-noise, high-sensitivity InGaAs image sensor.

C11118GA Spectrometer

The light to be calculated with an inbuilt image sensor is sent to a computer from the USB port for data acquisition purposes. The transmission grating of the spectrometer provides high throughput. The grating is made from quartz material.

The maximum spectral resolution of the C11118GA spectrometer is 20 nm. It has a maximum broadband stray light of -25 dB and a maximum spectral stray light of -30 dB. The C11118GA’s maximum wavelength reproducibility and wavelength temperature dependence are ±0.8 nm and ±0.08 nm/°C, respectively. The spectrometer also includes a number of features such as integration times from 6 to 40,000 µs, an optical numerical aperture of 0.22 and a 16-bit analog-to-digital conversion. The operational temperature of the spectrometer ranges from 5°C to 35°C.

The spectrometer incorporates a palm-size polychromator, which is combined with optical elements. The InGaAs image sensor is supplied using an image sensor driver circuit and is optimized for specific wavelength range. It incorporates a USB 2.0 interface, a power supply connector, the DLL library, and sample software. Data acquisition and PC connection are convenient, and users can set measurement conditions, receive and save data. Users can also generate graphical displays.

The spectrometer is ideal for life sciences, measurement of C-H group absorption, component analysis, water and soil analysis and NIR spectrometry.
