Introduction
The OS-8543 Prism Mounting attaches to PASCO’s
Educational Spectrophotometer (OS-8539). Use the
OS-8543 Prism Mount to convert the OS-8539 grating
spectrophotometer to a prism spectrophotometer. A
prism spectrophotometer has two advantages over a
grating spectrophotometer: a) It eliminates overlap of
the orders of spectral lines observed with a grating, and
b) The spectrum is brighter because it does not spread
over several orders or in both directions.
