Eisco Spectroscope

The Eisco Direct-Vision Spectroscope is a rugged, easy-to-use instrument designed for middle school classrooms. Featuring a durable plastic housing and an diffraction grating (≈ 500–600 lines/mm), students can confidently explore and decompose visible light (400–700 nm) and accurately measure spectral lines with ±5 nm precision. With an engraved scale directly on the spectroscope, learners can view and quantify emission lines from gas tubes, flame tests, or common light sources—turning glowing colors into data.

Standards Connections

These resources can be used to support standards-based teaching and learning.  They are not intended to meet the full scope of any given standard.  Only some standards are highlighted; many more standards may be connected!  We encourage you to explore and to let us know if you have any questions!

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling various media. 
HS-PS4-5. Communicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.
