340-1050nm Spectrometer Experiment Set DIY Blue-ray/Full-spectrum/Laser/Absorption Spectrum Testing for Windows System

Description:
- The observable wavelength range is about 340-1050nm, with a software resolution of 1nm. It can distinguish between light sources of 1-2nm, and the two spectral lines of 577nm and 579nm in mercury lamps can be absolutely distinguished; better resolution than the handheld spectrometer; The accuracy of measurement can rival that of commercial handheld spectrometers, as detailed in Bilibili's video.
- It can be used to measure the relative intensity and wavelength of blue light in LED lamps, as well as whether it is a full spectrum LED lamp, an eye protection desk lamp, and so on.
- It can be used to measure wavelength, fluorescence spectrum, absorption spectrum, filter band, distinguish laser diode wavelength, and reverse the light source through spectrum, etc.
- Using for Theremino_Spectrometer software (currently only applicable to Windows systems, but not to Windows systems installed on hardware for Apple, which may run unstable), and there is also software that I have modified the algorithm by myself. Please leave a note for your email if you need it and I will send the software and usage information together.
- It is very easy to use, just plug it directly into the USB port.

Application:
- Teaching demonstrations and students conducting optical experiments.
- Explain light source knowledge to children.
- Measuring the spectrum of LED lights can determine whether it is full spectrum.
- Measure the spectrum of the photon beauty instrument.
- Measure the wavelength of the feeding light meter.
- Check the blue light wavelength of computer monitors and mobile phone monitors.
- Some related companies provide employee onboarding training due to its simple structure and clear principles.
- Measure the passband of various filters (it is recommended to use a halogen lamp as the background light source), such as the protective band of astronomical filters and laser protective glasses.
- For reverse engineering, it can determine the light source used in certain detection equipment, as well as the wavelength.
- Because the wavelength is very accurate, after setting up the environment, it can be used to select the wavelength of the laser diode. For example, distinguishing between 522nm and 524nm models in the same batch of laser diodes can also be done using the secondary main pole, which is 1044nm and 1048nm, which is equivalent to amplifying the error.
- The software has an integration function, which can measure the spectrum of brief light sources, such as the spectrum of a remote control or flash.
- It is possible to simply measure the alcohol concentration, as shown in the figure below. The intensity change is still significant between 900-1000nm, and the environment that needs to be built is: halogen lamp + colorimetric dish + infrared filter (in fact, the measurement is the concentration change of water, just because the water concentration + alcohol concentration = 1).
- Used to demonstrate the absorption spectrum of chlorophyll.

Compared to Handheld Spectrometer:
- The waveform and peak wavelength are basically consistent, with little difference in relative intensity;
- The spectrum of a handheld spectrometer may experience some compression in the X-axis direction and some stretching in the Y-axis direction due to the small screen size.
- The eye protection mode of a mobile phone does not change the wavelength of blue light, but only lowers the blue light and increases the red light, so the screen will turn yellow.

Key points of chlorophyll absorption kit experiment:
1. The concentration of chlorophyll solution does not need to be very high, but it should be clear.
2. When verifying the Lambert-Beer law using the absorbance method, the concentration should not be too high.
3. You must first master the basic operation of the spectrometer before conducting this experiment. Don't worry, this experiment is actually very simple.
4. Halogen lamps are extremely hot, do not touch them directly with your hands.
5. The shell of this kit is 3D printed, with layer patterns and defects unique to 3D printed parts.
6. The turning on time of halogen lamps should not exceed 15 minutes to prevent the shell from softening.
