Abstract: A vaariable angle reflection accessory for use in reflection spectrometry characterized by a pair of fixed ellipsoidal reflectors positioned over the sample surface and a pair of rotatable plane mirrors positions at opposite sides of the sample surface. The spectrometer beam is brought to a focus at the first plane mirror, from which it is reflected off the first ellipsoidal reflector to a focus at the sample surface. The reflected beam follows a corresponding path back to the spectrometer. Rotating the mirrors in unison causes the beam angle of incidence on the sample surface to vary over a wide range while maintaining optical alignments and continuing to center the radiation on the same sample area.

Abstract: An optical rotor and a method for colorimetrically measuring material having an irregular or multicolored surface wherein an image of the surface is directed onto the rotor as it is rotated at a high speed in order to produce a continuously rotating image which appears to have a uniform color. In one embodiment, the optical rotor includes two pyramid-shaped mirrors which are mounted with their bases mated. The pyramid-shaped mirrors are surrounded by four concave spherical mirrors which define two apertures so that light beams of an image which are directed into one of the apertures strike the sides of one of the pyramidshaped mirrors at an angle which is a function of the angular position of the pyramid-shaped mirrors about an axis which passes through the peaks and bases of both. Thus, the angular position of the image which appears at the other aperture is a function of the angular position of the two pyramid-shaped mirrors and by rotating the two pyramid-shaped mirrors, a rotating image can be produced which appears to have a uniform color. In the other embodiment, two prisms are disposed in a housing defining opposing apertures so that the angle of incidence of the light beams of an image onto a surface of one of the prisms varies as a function of the angular position of the prism so that a rotating image can be produced at the other aperture by rotating the two prisms.

Abstract: A light source for near-infrared transmission and reflection spectroscopy can be constructed from a combination of a high power blue or blue-green light emitting diode (LED) and a phosphor element based on an inorganic material. The phosphor element absorbs the LED light and, in response to the LED excitation, emits luminescence that continuously covers the 700 – 1050 nm range. One possible material that can be used for such a near-infrared emitting phosphor element is a single crystal rod of Ti+3 doped Sapphire. An alternative near-infrared emitting phosphor material is a disk or rectangular shaped composite of Ti+3 doped Sapphire powder embedded in a clear optical epoxy or silicone encapsulant. Such a combination of a blue LED for excitation of a phosphor element that emits in a broad wavelength band has been widely used in white LEDs where the emission is in the 400-700 nm range.
