digital micrometer least count calculation
The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm

pitch /no of divisions of micrometer barrel
in this the one half of the polarimeter is made of glass and other half of the polarimeter is made of quartz
The importance of least count ( the highest degree of accuracy of measurement) helps calculate the margin of errors when doing measurements.
i need a laboratory experiments on polarimeter
biquartz polarimeter
to calculate the least count of travelling microscope first see the no. of division on the main scale say between 12 and 13 there are 20 divisions and the no.of division on vernier scale is 50 then 1 msd = 20 division 1 division = 1/20 msd=0.05 1vsd = 50 division least count = msd/vsd =0.05/50=0.001 so least count is 0.001 cm
well a polarimeter is an instrument for measuring the polarization of light. But Ive never heard of a half shade polarimeter and nor has Google :D
