Vernier Emissions Fiber

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.  Specifications Dimensions: 10.1 cm × 7.0 cm × 4.5 cm Power supply: USB powered Detector: Linear CCD Wavelength range: 350–900 nm Wavelength reporting interval: 1 nm Optical resolution: 3.0 nm (as determined by the full width of half maximum of hydrogen 434 nm peak) Wavelength accuracy: ±2 nm (as determined by hydrogen peaks) Experiments Spectrum of Atomic Hydrogen Planck’s Constant

Increase student engagement in your laboratory and classroom with the Go Direct Visible Spectrophotometer. Its quality optical bench allows for high accuracy and reproducibility, making this spectrometer an ideal option for upper-level courses. In addition, the spectrometer housing is aluminum, which helps alleviate temperature fluctuations during a long kinetics experiment.  The Go Direct Visible Spectrophotometer comprises a lamp with cuvette holder and a detector. These two pieces are held together magnetically, allowing them to be easily separated for high-accuracy emissions experiments with our Vernier Emissions Fiber.  To collect spectral, kinetic, or Beer’s law data, simply connect the Go Direct Visible Spectrophotometer directly to a tablet, laptop, or Chromebook™, via USB or Bluetooth® wireless technology. Data can be collected and analyzed using our LabQuest® 2, LabQuest 3, or free Vernier Spectral Analysis® software, which allows users to spend less time learning different interfaces and more time in the laboratory. The Go Direct Visible Spectrophotometer can be used in a variety spectroscopy experiments: Determine peak wavelength to collect data on solution concentration for studies of Beer’s law or to monitor rates of reaction.  Conduct enzyme kinetics experiments. Engage in equilibrium studies of absorbance vs. time or absorbance vs. concentration. Use the Spectrophotometer Optical Fiber to measure emissions from flame tests or other light sources.  Specifications Wavelength range: 380 nm–950 nm Reported wavelength interval: ~1 nm between reported values Optical resolution (FWHM): 3.0 nm Wavelength accuracy: ± 2.0 nm Absorbance photometric accuracy: ± 0.05 A.U. Typical scan time: ~2 s
