Wireless Spectrometer

Overview

• Spectral scans from 390 to 950 nm
• Fluorescence excitation at 405 nm and 500 nm
• Intuitive, software-based operation
• Built-in tools for routine analyses
• One-click light and dark calibrations
• Clear marking to indicate proper cuvette positioning

How It Works

Light from the LED-boosted tungsten light source passes through the solution and a high-quality diffraction grating. The CCD array detects the light and analyzes it. When used with the optional Fiber Optic Cable, the Wireless Spectrometer can perform emission spectroscopy experiments. Simply insert the Fiber Optic Cable into the cuvette holder and point the end of the cable at the light source to collect data.

Important Note: Solutions used within this spectrometer should be compatible with polystyrene (cuvette material) and ABS (spectrometer housing material). Use a glass cuvette or 12mm test tube for solutions with strong organic solvents like acetone, which will damage the plastic cuvettes.

The PASCO Visible Spectrometer is fully integrated with our user-friendly Spectrometry Software.
This free software is compatible with most student devices, enabling lab groups to quickly share and review their data with ease. Also available as a free, fully functional app, PASCO’s cross-platform Spectrometry Software improves the efficiency of analyses with features such as:

• Easy-to-use navigation
• One-click light and dark calibrations
• Automatic display and storage of sample data
• Onboard scan averaging and data smoothing
• Intuitive run renaming for improved data tracking
• Spectral graph correlates visible wavelengths with color
• Built-in Beer-Lambert law with linear fits for determining concentrations
• Print spectrum and results snapshots
• Export data as a .csv file or .png screenshot for further analysis in Excel, SPARKvue, or PASCO Capstone

Spectrometry Software includes four preprogrammed displays:

• Analyze Solutions: Wavelength vs. Absorbance
• Compare Concentration: Concentration vs. Absorbance (Beer’s Law)
• Change Over Time: Time vs. Absorbance (Kinetics)
• Analyze Exterior Light Sources: Wavelength vs. Intensity
