Abstract: Optical radiation generated by an auroral event is gathered by a fish-eye optical objective (12, 21, 22) and focussed by a telecentric lens (23) to a focal region where a two-passband filter (24) is located. The filter (24) passes two narrow bands of optical radiation, each band of which is centered on a specified wavelength. Rays in the two specified wavelengths are passed by a condenser lens (25) and a collimator lens (26) through an aperture stop in which a blocking filter (27) is located. The blocking filter (27) comprises two side-by-side half-size filters, each of which transmits a corresponding one and suppresses the other of the two specified wavelengths. A prism (28) diffracts rays each of the specified wavelengths by a different amount so that separated images in the two specified wavelengths are formed. A reimaging lens (29) relays the separate images to correspondingly different portions of a detector (30).

Abstract: A method and apparatus for measuring the absorption characteristics of complex lenses to light from a selected band of wavelengths, preferably wavelengths in the ultraviolet range, is disclosed. Light from an incandescent light source is passed through a tunable interference filter, which passes light having only wavelengths from the selected band of wavelengths, and is directed toward a first side of a lens to be tested. An integrating light detector, preferably a selenium solar cell is placed in close proximity to the second side of the lens to be tested, and senses substantially the total amount of light flux passing through the lens, regardless of the lens' complexity and light diverging characteristics. The output of the detector is fed through amplifier circuitry to a suitable indicating meter. A light impervious housing structure may be provided to prevent ambient light from impinging on the detector. The device utilizes inexpensive elements, is very accurate, may be hand held, and is simple to use.

Abstract: A filter assembly includes an incident medium, a spacer, at least one dielectric filter and an exit medium. The spacer is arranged between the incident medium and the at least one dielectric filter such that the incident medium and the at least one dielectric filter are spaced apart by a working distance and thereby enclose a medium of lower index of refraction than the incident medium. The at least one dielectric filter is arranged on the exit medium.

Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.
