This classroom/lab spectrometer offers a slightly larger 175 mm scale and independent, high-resolution movement for both telescope and table (30″ vernier). The interchangeable clamping unit makes switching between prism and grating work quick and repeatable — perfect for student experiments in wavelength measurement and refractive index determination.
Ordering Information: The prism and diffraction grating are NOT included in this kit. Contact us for the range of available prisms and gratings for use with this spectrometer.
