Measure visible light wavelengths directly

Turn color and light into measurable data. The Quantitative Spectroscope lets students move beyond simply seeing spectra to measuring wavelengths and analyzing spectral features with precision. With an integrated wavelength scale and diffraction grating, this handheld spectroscope makes quantitative spectroscopy accessible, reliable, and classroom-friendly.

Designed for student use, it provides clear, repeatable views of emission and absorption spectra from common light sources—making it an essential tool for physics, chemistry, astronomy, and earth science labs where understanding light–matter interactions matters.

Why Teachers Love the Quantitative Spectroscope

Durable and economical for classroom use: A rugged, cost-effective tool that stands up to repeated student handling while delivering reliable results.
Brighter, clearer spectra: Designed using a diffraction grating to produce sharp, visible spectral lines.
Built-in quantitative scale: Measures wavelengths from 400–700 nm with a precision of ±5 nm, enabling true measurement—not just observation.
Connects classroom labs to real science: Students use the same principles astronomers rely on to determine what stars are made of by analyzing spectral lines and absorption features.

What You Can Teach with the Quantitative Spectroscope

Used across middle school, high school, and introductory college courses to support national and state science education standards related to light, energy, and atomic structure.

Discrete energy levels in atoms and molecules: Show that atoms and molecules absorb and emit light only at specific wavelengths corresponding to quantized energy changes.
Element and substance identification: Use characteristic emission and absorption wavelengths to identify different gases and light sources.
Wavelength–color relationships: Measure visible-light wavelengths (400–700 nm) and connect numerical values to perceived color.
How we see color: Explain why objects appear colored based on which wavelengths they absorb, transmit, or reflect.
Emission vs. absorption spectra: Observe bright-line and dark-line spectra and relate them to atomic structure and real-world spectroscopy.
Applications in astronomy and materials science: Model how scientists determine the composition of stars and analyze materials using spectral signatures.
