1000:1 ultra-high signal-to-noise ratio/back illuminated low-noise cooling CCD/95% high quantization efficiency

SE Pro Refrigeration Fiber Spectrometer is a fiber spectrometer with thermoelectric internal cooling technology. It adopts a high-resolution optical platform and has the ability of high resolution and low noise. It is particularly suitable for low light detection occasions that require long-term exposure (such as fluorescence signal detection and Raman signal detection).

Typical application areas:

Fluorescence/Raman spectroscopy fluorescence intensity is usually one order of magnitude weaker than excitation light, belonging to weak light signals. In order to detect fluorescence spectra, high-sensitivity fiber optic spectrometers are generally required; In contrast, Raman signals are even weaker and generally require fiber optic spectrometers with the ability to expose for long periods of time.

The difference in intensity between the target light and the reference light in the absorption spectrum can reach up to three orders of magnitude, which requires a signal-to-noise ratio of over 1000:1 for the fiber optic spectrometer.

Microscopic spectroscopy requires the collection of spectral signals in the micrometer scale region, which requires fiber optic spectrometers to have the ability to detect weak optical signals.

In the angular resolution spectroscopy system, the optical signal is decomposed into various angles and collected one by one, which requires the spectrometer to have the ability of weak light detection and high-speed acquisition.

The application of SE Pro refrigerated fiber optic spectrometer in the above fields benefits from the following characteristics:

1. The SE Pro cooled fiber optic spectrometer with a signal-to-noise ratio of up to 1000:1 adopts a Hamamatsu thermoelectric internal cooling detector with excellent electronic design, which can lower the working temperature to 40 ℃ below the environment, suppress dark current noise, and improve the signal-to-noise ratio;

2. The detector of the SE Pro refrigerated fiber optic spectrometer with a peak quantization efficiency of 95% adopts a special back thinning technology, which introduces light into the PN node from the back and improves the quantum conversion efficiency, especially in the ultraviolet band;

3. In addition, the SE Pro refrigerated fiber optic spectrometer has undergone complex engineering design, integrating multiple advantages such as spectroscopy, electronics, and structural design, and has strong product strength.

4. Based on traditional CT optical path design, with a focal length of 60mm; Using NA.0.1 numerical aperture with high resolution, the optimal range is up to 0.2nm;

5. Platform based design, capable of configuring various specifications of gratings ranging from 300g/l to 2400g/l;

6 SMA905 optical interface;

7. High performance AD quantization sampling circuit, CCD quantization background noise ≤ 3RMS (10ms integration time);

8. Configure multiple communication interfaces such as USB and serial port, and set up an 8-pin external trigger interface.
