Cat. No. L4021 STUDENT'S SPECTROMETER. This instrument is in every respect similar to our L4020, but some of the higher finish has been omitted. All the essentials are carefully constructed and the optical parts are of the best quality. The circle is protected but only one vernier reading to 30 sec. is fitted to the instrument. The magnifying glass is omitted.
| Price, including prism | $60.00 |
