11 things about SpectralViewer, spectraView

1. By pressing the plot button, sliding the upper spectral image to the left and right, and entering two points with known wavelengths, you can plot the wavelength scale.

2. Press the graph button to show the light intensity distribution of the spectrum calculated by the camera image.

3. By using iPhone or iPad camera, you can measure a spectral intensity of the light by a spectrum image from a spectrometer.

4. Press camera > photo button to shoot a spectrum image dispersed by the spectrometer.

5. If the R0 wavelength is set as reflected light (0 nm) and the R1 wavelength is set only for the first time, the wavelength scale is plotted only by setting the R0 wavelength after the second time.

6. You can change the plot scale of spectral intensity by ＜＞ button.

7. Adjust the intensity of the input light by, for example, narrowing the slit so that each color does not exceed the maximum value 255.

8. If reflected light is observed, please be the in the area of the dark rectangle on the upper side of the camera screen.

9. For the data to be stored, a filter was applied so as to smoothly connect the intensity curves of the sensitivity wavelength regions of R, G and B colors.

10. You can save the plot with wavelength scale as image.

11. For iPadOS 13, open the Control Center and then tap the "Lock Orientation" button to avoid rotating the spectrum capture area.
