Go Direct® Emissions Spectrometer

Elevate emissions analysis with the Go Direct Emissions Spectrometer. This device connects via Bluetooth^® wireless technology or USB to a tablet, computer, or LabQuest^®. With the Go Direct Emissions Spectrometer, students can measure spectra of light-emitting samples in the range of 350 to 950 nm. The sensitivity of the linear CCD allows this spectrometer to be used with light bulbs, spectrum tubes, or the sun. 

Display and analyze spectral data on LabQuest 2, LabQuest 3, Logger Pro^®, or Vernier Spectral Analysis^®. For analyzing the emissions of a spectrum tube, an optical fiber is recommended. For measuring spectra of large sources (such as the sun) or comparing types of light bulbs, the optical fiber is not necessary.
