***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.
