Abstract: An inventive optical cell measurement apparatus comprises a light source (S) which emits light having a predetermined wavelength range, a first mirror (M1) which reflects the light emitted from the light source (S), a long light path gas cell (1) to which the light reflected on the first mirror (M1) is introduced, a second mirror (M2) which reflects light outputted from the long light path gas cell (1), a sensor (D) which detects the light reflected on the second mirror (M2), and optical elements (21,22) disposed in a light path extending from the light source (S) to the sensor (D) and each having a bifocal property with different focal lengths as measured in two directions (X,Y) perpendicular to the light path. With this arrangement, the aberration of spherical mirrors (6,7) disposed in the gas cell (1) is corrected, thereby preventing reduction of the transmittance of the gas cell (1).

Abstract: An optical system for determining an optical constant by measuring the absolute reflectance and the absolute transmittance of a substance by using an incoming side beam switching mirror for selectively switching the direction of a light from a light source to first or second converged light reflecting units. The first and second converged light reflecting units project the light from the beam switching mirror so as to be converged in an intersecting manner at the position of a sample holder that can be positioned to present a sample fitting hole or a through hole for measuring the reflectance/transmittance by providing the light to an exit side beam switching mirror and detector.

Abstract: An optical transmission spectrometer for transmission measurements of absorbing and scattering samples includes light sources mounted parallel to each other in a holder. The beams of light eminating from the light sources are directed through a beam-combiner. The beam-combiner includes a first refractive surface at an angle of incidence of 45.degree.. The first refractive surface refracts light toward a common axis. The beam-combiner includes a second refractive surface parallel to the first refractive surface for refracting the beam of light along a common axis parallel to the original direction of the beam of light. The beam-combiner can include additional refractive surfaces for other beams of light to combine the beams of light into a primary beam. The includes a collimating tube extending along the common axis for baffling stray light and directing the primary beam through a sample. A second collimating tube is provided on the side of the sample opposite the first collimating tube for baffling stray light passing through the sample. The second collimating tube directs the primary beam to a detector package mounted in a holder, where the detector viewing area of the sample is limited to that of the primary beam.

The probe includes a housing having a probe portion positionable proximate the sample, and an integrating chamber disposed within the probe housing and having a radiation input port, a sample port for passing diffused radiation to the sample and returning reflected radiation from the sample, a reference port, and an exit port to receive radiation reflected from the sample through the sample port. The probe further includes a guide for directing radiation to the radiation input port from a radiation source, and an element, responsive to the exit port and the reference port, for selectively conveying reflected radiation from the sample and the wall of the integrating chamber in the probe to the remote spectrophotometer.

Abstract: A spectrmeter radiation transmission system is disclosed which permits concurrent availability of numerous alternative accessory devices by conserving radiation throughput. Parabolic reflectors are used to provide alternating collimated and confocal segments of radiation, thereby largely eliminating the problem of vignetting (i.e., loss of radiation throughput due to beam size expansion). Modular enclosure elements are provided, inside which the radiation path travels between the parabolic reflectors.

Abstract: The advantage of sustained wavelength accuracy and mechanical simplicity of a spectrophotometer using a photodiode array as photometric detector and a fixed diffraction grating as dispersion means may be limited to a relatively short wavelength range by problems of stray light, second order errors and overloading of the detector at portions of the wavelength range. By utilizing repeat scanning of the array, each scan being modified by using a different source lamp and correction filters, freedom from the cited problems over part of each scanned wavelength range can be effected. A computer controls the scan sequence and combines the usable portion of each scan to produce error free operation over an extended range.

Abstract: A spectrophotometer optical section is presented which employs a fine positioning beam director which corrects for any deflections of the output beam path and accurately positions the optical beam on the detector slit of the spectrograph. The detector slit is chosen to have a size slightly smaller than the size of the optical beam at the detector slit to have high slit throughput without introducing spurious absorption. The sample cells need not be rigidly mounted thereby enabling use of a sample cell and cell holder which allows quick, easy interchange of cells.
