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.
