- Page 5 Figure I.1. The optical design is patent protected (U.S. Patent #5,122,127). The InPhotonics RPB also incorporates a manual shutter with calibration standard (see Section III.A). The shutter is in the “open” position when the red label is exposed.
- Page 6 Figure I.1. Schematic diagram of the RamanProbe; optics are not to scale. The InPhotonics RPB is coupled to the excitation source and the spectrograph via two optical fibers to allow remote measurements of samples. Each fiber optic subunit is provided in a protective polyurethane jacket.
- Page 7 Initial Setup and Operation CAUTION The use of controls and adjustments, or performance of procedures other than those specified herein may result in hazardous laser radiation exposure. When attached to a laser source, the RamanProbe provides a focused output of laser radiation with the laser class designated by the laser source.
- Page 8 III. Measuring Spectra with the Probe The RPB fiber optic probe has a tight focus spot that is several millimeters away from the final lens (usually 7.5 mm). The focused spot enables the user to pinpoint the measurement spot fairly precisely on the sample. The coaxial design also ensures the collection and excitation spots overlap as much as possible for highest Raman signal.
- Page 9 C can cause serious, damage to the optics. Do not heat the probe beyond 80 InPhotonics manufactures probes for immersion, high temperature, and high pressure use. An additional manual or description sheet should be attached to state the different mechanical and optical specifications and operational procedures.
- Page 10 IV. Laser Safety A. Sample Calculation of Nominal Hazard Distances of the RPB The following example shows how the nominal hazard distance of the RPB is calculated using the formulas described in the “American National Standard for the Safe Use of Lasers” (ANSI Z136.1-2000).
