Qwiic Visible Spectrum Emitter - 455-720nm - SparkFun SPX-21316

Index: SPF-23479

Qwiic Visible Spectrum Emitter is a visible light emitter developed by SparkFun, which contains as many as 9 discrete LEDs covering the spectrum from 455 nm to 720 nm . Each diode placed on the board emits light with a narrow peak wavelength, the only exception is the green LED. The module has a very broad spectrum of operation and can be used to implement spectroscopic projects, as well as scenarios in the field of photography or photochemistry .
