Abstract: A variable filter spectrophotometer, for use with sample and reference; has a main member, a filter unit, a drive, a detector, a light distribution system, and a clamping circuit. The main member defines first and second beam paths, which are intersected by the filter unit. The filter unit has filtering and opaque portions. The filter unit is continuously movable relative to the beam paths in a repeating cycle from a first filtering relation in which the filtering portion is interposed in the first beam path and the opaque portion completely blocks the second beam path, to a first dark relation in which both beam paths are blocked, to a second filtering relation in which the filtering portion is interposed in the second beam path and the first beam path is completely blocked, and to a second dark relation in which both beam paths are completely blocked. The filtering portion is variably transmissive along a direction of movement of the filter unit. The drive continuously moves the filter unit relative to the beam paths. The detector produces a signal responsive to light received. The light distribution system directs light separately to and from the sample and reference, to and from the beam paths, and to the detector. The clamping circuit clamps the signal produced by the detector during the filtering relations to the signal produced by the detector during the dark relations.

Abstract: A spectrum analyzing system measures or analyzes the colorimetric properties of a test sample at a preselected wavelength or range of wavelengths within the ultraviolet, visible, and near infrared regions. The system includes a spectrophotometer provided with a wideband light source, optical devices providing a sample light path and a reference light path, a chopper wheel allowing light to be directed alternately along the sample and reference paths interspersed with dark periods during which no light travels along either path, a dispersion grating for dispersing the light from both paths, a series of neutral density filters for limiting to various degrees the amount of light traversing each path, and a linear array of photodiodes for detecting the dispersed light at different wavelengths. The system also includes an electronic control section including a programmable power supply for controlling the intensity of light from the light source whereby the combination of the use of the neutral density filters in conjunction with controlling the intensity of light from the light source can be used to operate the photodiode array to prevent operation thereof near the saturated and dark current levels, and means for scanning the photodiode array at high speeds during rotation of the chopper wheel to provide a high speed spectral readout.

Abstract: An electrostatic device includes a fixed electrode to which is attached an end edge of a coiled or curved variable resilient sheet electrode. An insulative layer separates the two electrodes, being either bonded to the fixed electrode or being bonded to the resilient electrode. The resilient variable electrode is caused to unroll upon the application of an electric potential between the two electrodes. The device is particularly adaptable for use as a light gate. It is capable of being actuated by an electrical potential either in a light transmission mode or in a variable reflectivity mode.
