The frequency calibration of HeNe
laser interferometers commonly gives the average frequency with uncertainty calculated as standard deviation, whereas the calibration procedure at Laboratory for Production Measurements is upgraded with a computer program that also calculates Allan deviation, providing additional information regarding the time-varying of the frequency.
If the Pier Head skyline con-sisted of a rang e of concrete and glass space-age buildings, then t hene
w ventur e could be applauded, but to impose this sad fairground ride of a building on the other three, is really rather unf ortunate.
With the optional HeNe
laser, APC can also be detected.
Based on a frequency-stabilized Class II HeNe
laser, the ML10 Gold Standard system has axis range of 40m and works in temperatures from 0-40[degrees]C, with an environmental compensation unit that "normalizes" all temperature, pressure and humidity factors.

Operating with low-voltage DC, this cutting-edge technology eliminates the high-voltage supply required for HeNe
gas lasers, yet provides more power.
