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.

Optical spectroscopy in the visible light spectrum is a commonly used tool in different fields such as health, manufacturing, art, and forensic research. OSpectrometer implements basic spectrometer functions using the built-in camera and screen without requiring external devices or programs. - Visible light spectrum is transformed and mapped to a function that generates RGB (Red Green Blue) color values - A specific light wavelength can be selected and used to illuminate a desired target (i.e., close to the screen) - The whole spectrum or a specific part of the spectrum can be selected and scanned - Front camera is used to sense the reflection from the target object - Consistent and repeatable reflection/absorption amplitude with respect to the color spectrum - The result can be saved and shared - Works offline, no need to connect to any network or internet Privacy-policy: https://software.nanorescenter.com/osprectrometer-privacy-policy Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is in-app purchases: NSP32 nanoLambda Spectrometer at none against OSpectrometer's 2. NSP32 nanoLambda Spectrometer also leads on iOS requirement (13.0 vs 15.1). OSpectrometer's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.
