Abstract: In a calibration system for optical instruments of the type which make measurements at incrementally spaced wavelengths throughout a spectrum, a plurality of standard samples are measured by a master instrument and a field instrument. The measurement data obtained from each instrument are then statistically correlated to determine a calibration file which is stored with the field instrument. The calibration file includes identification on the field instrument of index locations at which the field instrument will respond to the same wavelength as corresponding index points on the master and includes correction coefficients for each of the index locations. The calibration file is stored in a computer connected to the field instrument and the computer is provided with a program to correct the measurements made by the field instrument in accordance with the stored calibration file.

Abstract: A system for rapid-scan spectral analysis comprising a concave holographic diffraction grating continuously rotated at a substantially constant angular velocity to provide a rapid scanning monochromator (a monochromator is used to transfer nominal regions of wavelengths out of the continuous light source). The unique sampling circuitry uses an optical shaft encoder. The angular velocity and angular acceleration of the grating are calculated from time measurements, just before the first wavelength of interest falls on the detector. This information is used to control the Analog to Digital converter sampling rate across the region of interest. The samples as a function of time are stored in a memory buffer so that each data point corresponds to a wavelength.

Abstract: A slow scan, frequency limited spectrometer having a screw mechanism for driving a rotatable grating is improved by incorporating and interlinking the following new constituent members with the screw mechanism: a cylindrical cam member with a groove and a constraint to attain a predetermined pitch, so that rapid scanning of a preselected wavelength range is achieved with the grating; a high torque, variable speed, direct current electric motor, so that the rapid scanning may be varied in speed; and, a liner potentiometer with a sliding contact, so that a remote wavelength readout of the variable rapid scanning can be obtained. Cylinder cam members of various pitches are also disclosed for use in scanning different wavelength ranges. At a low cost for improvements, the resulting spectrometer provides a variable fast scan, and is frequency selective.

Abstract: A wavelength reading apparatus for a monochromator comprises a monochromator utilizing a dispersion element for dispersing light in accordance with its wavelengths, a dispersion element driver unit for rotating the dispersion element to effect the tuning wavelength scanning operation of the monochromator and a wavelength counter for adding or subtracting a pulse, which is produced each time when the tuning wavelength of the monochromator changes by a predetermined wavelength increment, depending on whether the wavelength increases or decreases. The wavelength counter is set to a predetermined counting value, in response to a wavelength calibrating pulse produced when the tuning wavelength of the monochromator reaches a predetermined value, so that any counting value of the wavelength counter correctly represents the instant value of the tuning wavelength of the monochromator.
