iSPEX calibration instrutions
The iSPEX unit is composed of a backplate, tailored to your phone, and a detachable unit. There are two types of units available: a spectrometer version and a polarizer version. Each unit comes with a barcode for support purposes.
To install, remove any cases from your phone (screen protectors can stay) and ensure the camera is clean, as the iSPEX is an optical add-on. Choose the 1x zoom camera (you can find out by positioning the unit and check the screen if it gets dark.
To use with the iSPEX app, position the unit so the horizontal bar, referred to as the slit, aligns within the top box on your screen, making sure both parts of the spectrum are visible. Adjust the exposure if necessary, keeping in mind that overexposed images cannot be used. Press the capture button to take a measurement. The image will automatically be sent to our server for processing. Results, including graphs and data, will be accessible within seconds by pressing the 'MySPEX' button located in the top right corner.
