Technical Specifications
| Specification | Value |
|---|---|
| Collimator | Achromatic lens, adjustable slit |
| Telescope | Ramsden eyepiece with cross-wires |
| Scale | Circular, dual vernier readouts |
| Prism table | Height-adjustable, levelling screws, clamps |

How It Is Used
After levelling and focusing the collimator and telescope, a prism or grating is set on the table and light from a spectral lamp is passed through the slit. The telescope is turned to each spectral line and the angle read on both verniers, giving the angle of minimum deviation, refractive index, dispersive power or wavelength.
Frequently Asked Questions
What can be measured with the Spectrometer?
Angle of minimum deviation, refractive index, dispersive power and wavelengths of spectral lines.
How are angles read on the Spectrometer?
The circular scale is read through two vernier readouts, one on each side of the table.
