UV-NIR fiber optic spectrometer

1: The instrument works stably

The instrument is stable in USB communication, and anti-interference chips are added to the USB communication between the data acquisition card and the computer. The USB can still work normally in strong electromagnetic environments. Even if it is affected by external interference, the built-in USB restorer on the data acquisition card can bring the USB communication back to normal without the need to plug or unplug USB interface cables, greatly improving the stability of operation and ensuring long-term continuous operation of the instrument.

2: Baseline stability

The data conversion chip of the instrument data acquisition card abandons the traditional simple AD conversion chip and uses a CCD dedicated sampling chip, which can maintain baseline stability in the event of power supply interference and fluctuations, making the collected data stable, reliable, consistent, and repeatable.

Measurement software SpectraPro (customizable according to requirements)

The SpectraAnalysis software has functions such as displaying multiple spectral lines, processing multiple spectra, taking screenshots, caching spectra, peak/valley searching, half width measurement, coordinate conversion, and recording spectra. It mainly consists of a console window, a spectrum window, and a spectral line list window. The console window mainly sets the parameters for USB data collection; The spectrum window displays real-time spectra or file spectra collected from USB, and can also open spectral recording files; The spectrum setting window mainly determines the display mode of spectral lines.

The text annotations included in the spectrogram, the right mouse button dragging of spectral lines, the indicator bar, mouse pointing, and other functions make the operation of the spectrogram quite smooth, making it convenient to obtain any information about the spectral lines At the same time, it can be combined with Microsoft Office software to provide the function of exporting spectral data as Excel and Word documents. The software saves the spectrum as a file in *. ssp format, which can be opened by double clicking or dragging the file into the window.

Color measurement:

This function uses the internationally authoritative full spectrum method (without V (λ) correction error) to measure the spectral power distribution, chromaticity coordinates, correlated color temperature, color deviation, color tolerance, peak wavelength, and color rendering index (Ra) of LEDs, energy-saving light sources, phosphors, etc. The measurement band range is 380nm~780nm. The corresponding electrical equipment can measure the voltage, current, power, power factor, etc. of the light source. The measurement and control of the product are all completed by computer software, which is easy to operate and has powerful functions for light source testing and data analysis and processing. The measurement data can be exported to various file formats such as Excel, txt, and ssp (spectral file), making it very convenient for analysts to calculate and analyze.
