Abstract: Lens fogging or frosting on inside surfaces of an instrument lens may be reduced or prevented by sealing the instrument housing. Damage or rupture of the sealed housing due to an increase or decrease in pressure within the housing may be avoided while reducing introduction of moisture into the housing by venting the housing through a tube to a location having a relatively lower humidity.
