Wireless Spectrometer (Vis) - PS-2600A
Measures intensity, absorbance, and transmittance across the visible spectrum. Includes fluorescent excitation at 405nm and 500nm.
Product Summary
The award-winning PASCO Wireless Spectrometer is specifically designed for introductory chemistry, biology, and physics labs. It pairs effortlessly with student devices (Mac®/Windows®, Chromebook™, iPad® and Android™ tablets) via Low Energy Bluetooth® (BLE) or USB and includes free PASCO Spectrometry Software for easy operation. Scan times are fast, ranging from milliseconds to minutes depending on the experimental settings. This enables students to quickly gather absorbance spectra across the visible spectrum. After specifying a target wavelength, students can select a display to compare absorption to concentrations (Beer’s Law), track rates of reactions (kinetics), or investigate emission spectra using the optional Fiber Optic Cable accessory.

How Does it Work?
Light from the LED-boosted tungsten light source passes through the solution and into a slit sending light through a high-quality diffraction grating. Colors separate across a sensor and an image of the slit illuminate over 1000 sensors in the array on the other side of the spectrometer. The CCD array detects the brightness of each color of light so you can further analyze the brightness of each particular wavelength. When used with the optional Fiber Optic Cable, the Wireless Spectrometer can analyze light from 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: Solvents used within this spectrometer should be compatible with polystyrene (cuvette material) and ABS polymer (spectrometer housing material). Use either a glass cuvette or 12mm test tube for solutions with strong organic solvents like acetone, which will damage the plastic cuvettes and the interior of the spectrometer if spilled.
