Abstract

A housing for a Time-of-Flight (ToF) range meter includes a wall structure defining a first optical beam path to an emitter of the ToF range meter, and a second optical beam path to a detector of the ToF range meter, and a transmissive optical diffusor configured to cover the beam path to at least one of said emitter and said detector. The housing may be connected to a ToF range meter into a ToF ranging device. Such a ToF ranging device where the ToF ranging device is directed to measure a distance to a reflector member to determine a distance which correlates to the weight of the selectively engaged weights.
