    Abstract: Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving location (2) for receiving a sample (3) for analysis; an illumination arrangement (4) for directing light towards a received sample; a detector (6) for detecting light reflected by a received sample; and collection optics (5) for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer (42) and a half beam block (45a, 45b) which is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from reentering the interferometer. A half beam block (45a) may be disposed in the optical path between the interferometer and the light source (41) for blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam block (45b) may be disposed in the optical path on the opposite side of the interferometer than the light source.

    Abstract: A shutter assembly for use with a spectrometer having at least one source of optical radiation such as at least one laser capable of generating an excitation light beam having an illumination path. The shutter assembly includes a shutter having at least one of (i) at least one calibration material capable of generating a consistent spectrum within wavelengths utilizable by the spectrometer and (ii) a mirror capable of diverting at least one of the illumination path and a collection path relative to a calibration standard capable of generating a consistent spectrum within wavelengths utilizable by the spectrometer. The shutter assembly further includes a mechanism capable of moving the shutter into at least a first position in the path of the light beam and a second position out of the path of the light beam to enable a sample to be analyzed.

    Abstract: A radiation pulse, such as from a solar simulator, is spectrally analyzed over a selected sampling pulse that is shorter in duration than the radiation pulse and is timed to begin after the start of the radiation pulse. A deformable membrane mirror is controlled to function as a high speed shutter in the path of the radiation pulse. When not deformed, the mirror reflects the radiation pulse into an optical instrument, such as a spectroradiometer. A sampling pulse is generated for a selected time after the start of the radiation pulse and is applied to the mirror to ensure total reflection of the radiation pulse only for the duration of the sampling pulse. Controls are provided to adjust the start time and duration of the sampling pulse, and to adjust the sensitivity of sensing the start of the radiation pulse.

    Abstract: A flicker photometer comprises generating means (1, 8, 4) for generating two beams of light of different colours. Both beams are directed to a viewing means (190), and a subject can vary the intensity of light from one beam relative to the other. The colour of the light seen by the subject is caused to alternate by a shutter (18) which is rotated about an axis by a motor, the shutter having a portion which extends non-perpendicularly relative to the axis to facilitate a compact construction of photometer. The performance of the photometer is improved by screens which scatter light before it reaches the subject. A first of the screens reflects light from one beam, whilst a second screen transmits light from the other. If light of wavelengths to which the eye is less sensitive is passed through the second screen, whilst light of a wavelength to which the eye is more sensitive passes through the first screen, the screens help to make it practicable for the generating means to use a single lamp (1) to produce the light for both beams.
