An apparatus for measuring an optical property of a fluid. The apparatus may comprise a light source for projecting a beam of optical energy through the fluid and a reflector positioned opposite the fluid from the light source. The apparatus may also comprise receiver optics defining a receiver aperture. The reflector may be selected to under-fill the receiver aperture by a factor of at least 2.5. According to various embodiments, the apparatus may also comprise a reflector purge nozzle positioned at least partially between the reflector and the fluid. In addition to, or instead of the under-fill factor described above, the reflector may be selected to have a diameter less than a diameter of the reflector purge nozzle by a factor of at least 6.
