***For Trimble users, issues can occur if copper-coated prisms with anti-reflection coating are used with SX Series instruments.

While there is no issue with the copper coating, the anti-reflection coating on the front of the prism is optimised for Leica EDMs which use a wavelength at 0.85µm and 0.66µm, as opposed to the wavelength of the Trimble SX Series EDM, which is at 1.55µm, thus the front reflection is larger. 

Absolute prism constant (Trimble, Topcon, Sokkia etc) -16.9mm.

Leica prism contant +17.5mm.
