EQ4000 is a high-resolution spectrometer that uses a high-resolution optical platform, suitable for occasions that require fine spectral resolution.
The EQ4000 high-resolution spectrometer adopts a combination of a focal length of 100 mm and a numerical aperture of 0.11, which enables the spectrometer to achieve the best balance of resolution and sensitivity without increasing its own volume. It can provide an optical resolution of up to 0.10nm for laser characterization. , Gas absorption measurement and plasma analysis provide better spectrum measurement.
The EQ4000 high-resolution spectrometer has high-speed and high-sensitivity technology, which can put users’ products in a technologically leading position and give products stronger bargaining power; it can be matched with low-cost optical fibers, free trial services can be provided, and bulk purchases can be cheaper.
EQ4000 spectrometer resolution:
1. The resolution is inversely proportional to the sensitivity. The smaller the slit, the lower the sensitivity, but the resolution is better.
2. The greater the number of grating lines, the higher the resolution and the smaller the irradiation wavelength range.
[Features]
1. The high-resolution optical platform achieves the best balance of resolution and sensitivity without increasing the volume of the spectrometer itself;
2. Full-spectrum technology, using variable blazed grating, solves the problem of wide-spectrum efficiency balance and high-order interference, and the widest spectrum coverage reaches 300-1100 nm;
3. Ultra-high resolution, providing the highest optical resolution of 0.1nm;
4. High-speed control technology can set a new integration time within 1ms, saving time for spectrometer control;
5. Marking technology, can query the completion status of the spectrometer at any time, interrupt and re-collect at any time, without long waiting;
6. Bottom call technology, support system integration development, facilitating users to develop spectrometer application programs more quickly.
