"Every high school in the country should have one of these!" ~ Paul Hewitt, Author Conceptual Physics

Teach spectroscopy with live video! Digitally capture an individual spectrum, and then compare it to a series of known spectra. The included camera and software make this an easy and inexpensive alternative for studying quantitative spectral analysis using a standard spectroscope.

The RSpec Explorer allows multiple users to experience the benefits of quantitative spectroscopy at the same time, and in meaningful ways. Until now, it’s been nearly impossible to teach about light and color using traditional tools like diffraction gratings because you can’t determine if all your students are even seeing the same results of their experiments. But with the RSpec Explorer’s camera and software system, you will be confident knowing that every student is seeing the same thing. The result is that they’re spending less time wondering what they’re looking at and more time on impactful tasks like: learning how to measure the wavelength of visible light, understanding the different line spectra from ionized gas tubes, or studying the diffraction of light.

The RSpec Explorer’s powerful and intuitive software allows students to graph and displays the results, helping them interpret what they’re seeing. Students can also export experimental data to Excel, record their experiments, and leverage the built-in library of gas spectrum lines to compare one ionized gas to another.

Simply position the RSpec Explorer on a stable surface, one or two meters from the light source. There’s no fine-tuning or adjustment necessary. The internal video camera includes a built-in diffraction grating and it auto-focuses and adjusts for current light conditions. The system works with any XP or more recent Windows operating system and Macs. You can set up the camera and capture a spectrum in about 90 seconds!

Notice: The RSpec Explorer is not compatible with Chromebooks.
