    Abstract: Radiant energy sensor is protected from severe environments with a radiant energy sensor assembly that off-sets the sensor from the environment. The sensor assembly includes a radiant energy sensor, a pair of reflective walls facing one another, one of the walls having a transmissive aperture for receiving radiant energy over a wide angle of incidence, an entry, the other wall having a transmissive aperture for passing energy from behind the wall to the sensor, an exit, with the walls having the reflection characteristics such that the radiant energy entering the entry aperture at any angle is always reflected to the exit aperture. The reflective walls may be paraboloids or Fresnel surfaces in geometry.

    Abstract: There is provided a laser energy measuring unit whose laser energy measuring range is widened. The laser energy measuring unit has a filter provided within an optical path of laser to attenuate energy of the laser, a calculating section for measuring the energy of the laser passing through the filter and a condenser lens provided on one side of the filter for condensing the laser. The filter has a shading portion for blocking a center part of the laser beam from transmitting through the filter at position coincident with the center of the laser. The center part of the laser where its energy is large is cut by the shading portion and the calculating section measures the part where its energy is not so large. Thereby, it is possible to widen the laser energy measuring range.

    Abstract: In one embodiment, apparatus is provided with a light source, an optic element, at least one photosensor, and a control system. The optic element has a reflective material on a surface thereof, and is positioned to receive and reflect light emitted by the light source. The at least one photosensor is mounted to the surface of the optic element on which the reflective material resides, over a portion of the optic element on which the reflective material does not reside. The control system is operably associated with both the photosensor(s) and the light source, to regulate the light source's light output in accordance with measurements received from the photosensor(s).

    Abstract: A light-measuring device for microfilm cameras which is adapted to measure in a point-by-point manner the brightness of an object plane. A small area of an object plane is projected by means of suitable light source via a measuring objective lens onto a measuring photoelectric cell. Light-conducting means are optically aligned with the objective lens and the light source. The photoelectric cell is mounted in the light-conducting means and has an end surface which is coplanar with an end surface of the light-conducting means. The measuring objective lens serves to also project a pattern of light defined by the shape of the end surface of the light-conducting means onto the object plane.
