- n. A polariscope; more specifically, an instrument for measuring the amount of polarized light in the light received from a given source, or for measuring the angular rotation of the plane of polarization. See photo-pola-rimeter, polaristrobometer, and saccharimeter.

And the only difference between the two drugs as far as detection goes is that, when viewed through an optical rotatory device called a polarimeter, dextromethorphan rotates light to the right, and levomethorphan rotates light to the left.
_ -- For this purpose a special instrument, known as a polarimeter, is required, details of the construction and use of which would be out of place here.
When that is done I place the extract into the polarimeter, which looks very much like a telescope.
The labs in my building did not have a polarimeter or any way to test for levomethorphan.
The name originates from a prior study by Biot and Persoz who used the polarimeter designed by the former and established that the solution of cane sugar which rotates the polarization plane of light to the right, rotates it to the left on the addition of a dilute acid.
So they used a polarimeter to mimic the possible effect of a supposed "sunstone" crystal, but the article doesn't detail exactly what sort of crystal that might be.
Further research will test whether the actual crystals from Scandinavia and Iceland work as well as the sensitive polarimeter. feldspar, which when viewed from certain directions exhibits a gemstone.
Further research will test whether the actual crystals from Scandinavia and Iceland work as well as the sensitive polarimeter.
For a "sunstone" they used a polarimeter, a device that measures polarization.
Using a polarimeter, he measured the polarised light bouncing off these models and showed that the stronger those reflections, the more flies became stuck to them.
