The N Series Cooled NIR Fiber Spectrometer is the core component that adopts an InGaAs linear image sensor, which has high sensitivity and stability in the near-infrared region. It is professional spectroscopy equipment for scientific research-grade near-infrared applications. It has the characteristics of small size, easy operation, and excellent performance.

Features

• Support GPIO

• Cooled InGaAs Detectors

• Batch Consistency Control

• High signal-to-noise ratio, low stray light

• Transmitted Light Paths

Technical Advantages

1. High sensitivity, high dynamic range

The N series spectrometer features Hamamatsu InGaAs linear image sensors, with TEC cooling, up to -20 °C, which makes the detector less noisy, which makes it more suitable for low-light detection; the signal-to-noise ratio and dynamic range can reach 15000:1.

Continuing the high-throughput structure design of HiNa series, F/2 can not only fully couple the input from 0.22NA fiber, but also has design redundancy, which can be compatible with unique fiber with a larger numerical aperture or customized input optical paths.

2. Powerful PC software

The PC software provided with the spectrometer-FLAVOR is powerful software. In addition to the basic spectrum acquisition control functions, it also has functions such as saturation and automatic adjustment of the integration time, recording of the real integration time, and automatic peak finding. At the same time, the software also includes characteristic functions such as wavelet smoothing with patented technology.

SDK supports Windows, Android, and Linux operating systems, and can provide secondary development packages in C#, C++, Java, Python, and other languages.

3. High stability

0~40℃, the spectral resolution remains unchanged, which is the best choice for industrial applications.

4. Simple to use

No configuration, preheating, plug and play

Separate 5V DC power supply

Because of the limited number of pixels in the spectrometer detector, there is a situation where only a few pixels make up a single spectral peak at the high spectral resolution, resulting in an unsmoothed peak, as shown in the figure below.

The figure shows an example of a drift in the peak position due to the temperature drift of the spectrometer at different temperatures for the same spectral peak. The spectral peaks are not symmetrical because the number of pixels that make up the spectral peaks is small, and the highest pixel of the spectral peak is shifted by one pixel from do to right under the effect of temperature drift.

At this point, we have two ways to evaluate the drift of this peak position.

1. Look at the position of the highest pixel point. Obviously, the peak position is shifted by one pixel, which translates to about 0.15 nm.

2. Fit the peaks before and after the drift and find the peak point of the fit, which is between two pixels. The drift of the fitted peak point is about 0.07nm

So which of these two methods is the right one? We believe that the second one is correct and reflects the true drift of the peak position. The reasons are as follows.

1. The high resolution leads to a low sampling rate of the pixels of the spectral peaks, and directly looking at the shape of the pixels together does not reflect the actual shape of the peaks.

2. The spectral peaks are physically closer to the symmetric distribution, and the drift of the peak position does not cause the peak shape to change.

3. By fitting all the pixels that make up the spectral peaks, the peak shape obtained is closer to the physical reality of the peaks.

Therefore, using the fitted peak shape to determine the peak position and evaluate the drift of the spectrometer is the correct method.

In practice, is it all necessary to do so? It depends on the situation.

If 1. The spectral resolution is low, and the sampling rate of the spectral peaks is high, i.e., it takes more pixel points to compose a peak, and these pixel points themselves are connected into a smoother and more symmetrical peak shape, then you can directly find the position of the highest pixel, or between two pixels, and confirm the peak position by visual evaluation.

2. With High spectral resolution and the need to know precisely the peak value, the above fitting method is needed. The fitting can be done by Spline algorithm, or by Gaussian or Lorentzian fitting, and the reader can choose according to the spectral nature of the sample under test. If you don't know how to choose, use Spline.
