    Abstract: A device for dividing a laser beam, e.g. into parallel equidistant beams includes a glass plate with two opposing planer, parallel surfaces. A transmission grating is arranged on one glass surface. A reflecting layer is applied over the grating, and an opening is arranged in the layer at half the length of the plate, for taking the beam, which is to be divided, to and through the grating. The laser wavelength and the grating line density are selected to give total reflection at the free surface of the glass for a beam diffracted at the opening of the grating. By altering the angle of incidence of the beam, the distance between the subdivided beams can be continuously varied within given limits. The device is also utilizable for combining a plurality of separate beams into a single beam. (FIG. 3).

    Abstract: Apparatus to perform correlation spectroscopy utilizes a zero dispersion monochromator having entrance, intermediate and exit slits. A ruled grating is located in the beam path between entrance and exit slits and is operable to disperse a beam of radiation incident thereon both prior and subsequent to radiation passage through the intermediate slit. A first axis is parallel to the grating rulings, the entrance and exit slits symmetrically disposed at opposite sides of a plane bisecting and normal to a line extending between the entrance and exit slits, the plane also passing through the intermediate slit. That axis is located to have intersection with and to extend at an angle .PSI. relative to a normal to the plane that passes through said intersection thereby to substantially eliminate spectral overlap. Further, an array of sets of slits is provided adjacent the intermediate slit position of the monochromator, the sets of slits in the array being successively movable into the focal plane at the intermediate slit position.

    Abstract: A filter spectrograph unit for use in a micro-Raman spectrometer system or a remote sensing system is formed by combining an infinitely variable spectral line rejection filter (having appropriate entrance optics) functionally and operatively with a dispersing spectrograph. The line rejection filter is a modified form of a zero-dispersing double monochromator having an input light signal including laser light scattered from, for example, minute Raman-active particles. The modified double monochromator includes an acylindrical mirror positioned so that the laser line will exit through an aperture in the mirror and all other spectral lines will be reflected and reformed by the modified double monochromator into an output light signal containing all of the original spectral information, less the rejected laser line. The dispersing spectrograph is integrally coupled to the modified double monochromator and produces from the output light signal a display of the entire Raman spectrum suitable for parallel readout and rapid data analysis.

    Abstract: The present invention provides a spectrometer, comprising: an inlet for the receipt of incident light; an optical path for transmitting the incident light from the inlet to an analysis plane; a focusing element located along the optical path, wherein the spectrometer has an in-focus position in which a focal point of the spectrometer and the analysis plane coincide; and a controller adapted in use, when a removable light disperser is placed along the optical path, to cause the spectrometer to be in the in- focus position by controlling the position of the focusing element relative to the analysis plane. The spectrometer is used in the analysis of light from a light source and, due to the ability of the controller to manage the focus point by way of moving the focusing element, the spectrometer is able to bring itself into an in-focus configuration without the need for a user to intervene.

    Abstract: The invention relates to angle-limiting optical reflectors and optical dispersive devices such as optical spectrum analyzers using the same. The reflector has two reflective surfaces arranged in a two-dimensional corner reflector configuration for reflecting incident light back with a shift, and includes two prisms having a gap therebetween that is tilted to reflect unwanted light and transmit wanted light. A two-pass optical spectrum analyzer utilizes the reflector to block unwanted multi-pass modes that may otherwise exist and degrade the wavelength selectivity of the device.
