XL-500 portable BLE spectrometer device is required. Please visit https://nanolambda.myshopify.com/ for more details. XL-500 is an ultra compact Bluetooth Spectroradiometer based on disruptive digital-nano convergence technology. While its size is compact, the features and performance is comparable to conventional industry popular equipment. It is easy and convenient to use as a portable device with smartphone app, as a spectrum recorder with internal memory and rechargeable battery. XL-500 is individually calibrated and provides device-to-device repeatability. This app supports: 1) Emission measurement (SPD, PPFD, LUX, CRI, CCT, CIEXYZ, CIExy, CIEuv ) 2) Periodic measurement (as spectrum recorder) 3) Reflection measurement (relative-SPD, CIEXYZ, CIELab, CIExy, CIEuv) Start the nanoLambda's latest BLE spectrometer adventure now.
