The software boasts itself as a fast and convenient spectral data collection tool when paired with the LinkSquare spectrometer.

Built to create custom databases, the software helps you collect and view the spectral data of whatever matters to you.

You can convert the collected data to the format of your choice and export it to third party software for analysis. Of course, you can maintain data ownership.


Making your own applets can’t be easier! Once you have collected spectral data from your samples to create a database, you can upload the database to our machine learning server.

Our machine learning server provides a DIY applet creation tool by analyzing the samples of each item, distinguishing spectral features, defining spectral identity, creating a database, and making an applet that can be downloaded and viewed as an applet in the LinkSquare app.

Literally, the only limit is your imagination.
