    Abstract: A handheld device for infrared reflectance measurements of samples for identification of the sample materials is a self-contained portable unit built into a handheld housing. The housing includes a window and optics on a bench adjacent the window, so that the optics will be aligned with the sample when the device is placed directly against the sample. The optics include a broad-band IR light source (ordinary lamp) shining onto an acousto-optic tunable filter (AOTF), which passes narrow-band IR light with a swept frequency; a lens focussing the IR through the window onto the sample; and a reflectance detector aligned with the window of the housing to pick up reflected light. A computer, which may be mounted in the housing, compares the detected reflectance spectrum with stored sample data spectra, and identifies the material or the components of the material and their proportions. Inclusion of all the parts inside the housing allows the device to be portable; this is made possible by the alignment of the lamp, AOTF filter, lens, window, and detector, which has high optical efficiency, and by elimination of optical fibers.

    Abstract: A method and apparatus for use in the recycling of post consumer or post industrial waste carpet or Polyamide-6 and/or Polyamide-66 containing non-carpet waste utilizes a hand-held portable device utilizing spectroscopic principles to accurately and quickly identify the material of the waste (carpet). The spectrometer envisioned for this task includes an infrared radiation source for illuminating the waste (carpet) sample, a selector for selecting a predetermined number of discrete wavelengths and a detection system to detect reflected radiation within the discrete wavelengths. The selector can be either a plate with a plurality of slots which positionally correspond to locations in a dispersed light beam according to the predetermined discrete wavelengths or a plurality of filters selected to pass the discrete wavelengths. The selection of the discrete wavelengths can either take place before the carpet sample is irradiated or can take place by selecting the discrete wavelengths from reflected radiation.

    Abstract: There is described within a portable, battery-powered multiple filter infrared spectrometer consisting of a highly efficient optical system employing an infrared source with a chopper, from which IR energy passes through compound parabolic concentrators (CPC's) and is directed by a beamsplitter to the external sample, where the beam intersects with the sample via reflection and is returned through the CPC and beamsplitter to a stationary filter assembly and discrete detector array where the energy is converted to an A.C. (alternating current) signal. This current energizes an LED bar graph display for spectral identification. This method and apparatus is used to determine IR spectra of solids, liquids on a mirror, and gases in a container with a mirror to reflect light.

    Abstract: A dental plaque disclosing light for use in conjunction with a fluorescent dye plaque disclosing solution contained in a periodontal area of an individual's mouth is disclosed. A parabolic reflector supports a light source providing only light which causes the fluorescent dye to fluoresce. The light source is located in conjunction with the parabolic reflector to cause the parabolic reflector to project a solid, converging cone of light. Preferably, the light source is located forward of the focus of the parabolic reflector. A power supply is selectively connected to the light source for illuminating the light source. The power supply may be one or more batteries, and if the batteries are of the rechargeable type, a means for selectively recharging the batteries is connected to the batteries. A lens is supported adjacent the light source for projecting a solid, diverging cone of light having an axis concentric with the axis of the converging cone of light. A casing which supports the parabolic reflector also supports a reflecting surface adjacent the parabolic reflector such that, when the converging cone of light and diverging cone of light are directed toward the individual's mouth, the light reflected by the fluorescent dye is reflected by the reflecting surface and directed toward the individual's eyes. The light source may be a lamp and a filter means covering the lamp for filtering and passing therethrough only light which cuases the fluorescent dye to fluoresce.
