Abstract
A self-calibrating optical reflectance probe system having an illuminant light source to illuminate a sample material, optical pickup means to collect reflected light from the sample material, and an articulated white reference reflection standard for illuminant reference to provide a system capable of accurately measuring optical reflectance and automated verification of proper operation. The probe system preferably employs an uncomplicated mount using a single pipe fitting and clamp.
Claims12
A mount for an optical reflectance probe having a probe housing with an exterior surface, the mount comprising a pipe fitting and means for securing the probe housing to the pipe fitting, the pipe fitting having an opening at a first end thereof, the pipe fitting being sized to receive a portion of the probe housing therein through the opening thereof, the securing means being disposed at the first end of the pipe fitting and configured to secure the probe housing to the pipe fitting by engaging the exterior surface of the probe housing while the portion of the probe housing is within the pipe fitting.
A mount for an optical reflectance probe having a probe housing with a threaded exterior surface, the mount comprising:
- a sanitary pipe fitting sized to contain an end portion of the probe housing and having an integral curved viewport window to reduce reflected light from the window surface;
- and
- a clamping assembly coupled with the sanitary pipe fitting for mounting the end portion of the probe housing within the sanitary pipe fitting, the assembly comprising a pipe fitting flange threadably engageable with the threaded exterior surface of the probe housing, and a clamp for securing the pipe fitting flange to the sanitary pipe fitting.
