When the objective lens 50-fold, 3-fold the standard deviation ([sigma]) is less than 0.04 m, when the objective lens 100-fold, 3-fold the standard deviation ([sigma]) of less than 0.02μm
At 50 x objective, the result of 3 times the standard deviation (s) is less than 0.04 m, 100 times the objective, the result of 3 times the standard deviation (s) is less than 0.02 sm
The 3 times standard deviation (σ) of 50 times objective lens is less than 0.04 μ m, and the 3 times standard deviation (σ) of 100 times objective lens is less than 0.02 μ M
