Beam Deviation is the maximum deviation from parallelism, expressed in seconds of arc, of any single return beam from any of the 6 sub-apertures of the retroreflector, when the retroreflector is fully-illuminated.

Exiting Wavefront is the resultant maximum peak-to-valley wavefront deformation from a fully-illuminated retroreflector, where lambda = 633nm.

Certain high accuracy models may be heavier than indicated here. Check with us for actual weight.
