Abstract
A ranging apparatus works to measure a distance to an object and includes an emitter, a receiver, a housing, an optical window, a heater, an outlet hole formed in the housing, a power conductor, and a guide. The housing has the emitter and the receiver disposed therein and also has the optical window formed therein. The heater supplies heat to the optical window. The power conductor connects with the heater and extends outside the housing through the outlet hole. The guide is disposed in the housing and works to guide movement of the power conductor toward the outlet hole. The guide is equipped with a cover which covers at least a portion of the power conductor and is less able to reflect light emitted from the emitter and light reflected from the object than the power conductor.
