Abstract: Antireflection multilayer coatings with only three or four layers are proposed for the production of laser resistant optical components with minimal residual reflection and high transparency for UV light in a wavelength range approx. 150 nm to approx. 250 nm at large angles of incidence in the range of approx. 70° to approx. 80°, particularly in the range between approx. 72° and approx. 76°. For incident p-polarized UV light three-layer systems can be used, in which a layer of low refractive material, in particular magnesium fluoride is arranged between two layers of high refractive material and, in the case of the specified wavelength, of minimally absorbent material, in particular of hafnium oxide or aluminum oxide. For example, this allows a residual reflection of perceptibly less than 1% to be achieved in the case of a wavelength of 248 nm at angles of incidence in the range between approx. 72° and approx. 76°.

Abstract: A vehicle photosensing system includes a photosensor array that is disposed within the interior cabin of the vehicle and having a field of view forward through the windshield of the vehicle. The photosensing system further providing a control for either controlling operation of a vehicle headlight or monitoring a surface condition of the windshield of the vehicle. If controlling the vehicle headlight, preferably the control transitions the headlight from a first beam mode to a second beam mode in response to detection of a headlight and/or a taillight by the photosensor array within its forward field of view. If monitoring a surface condition of the windshield of the vehicle, the photosensing system operates the vehicle's windshield wiper system in response to a signal generated by the control.

Abstract: An optical apparatus for producing chromatic dispersion. The apparatus includes a virtually imaged phased array (VIPA) generator, a mirror and a lens. The VIPA generator receives an input light at a respective wavelength and produces a corresponding collimated output light traveling from the VIPA generator in a direction determined by the wavelength of the input light, the output light thereby being spatially distinguishable from an output light produced for an input light at a different wavelength. The mirror has a cone shape, or a modified cone shape. The lens focuses the output light traveling from the VIPA generator onto the mirror so that the mirror reflects the output light. The reflected light is directed by the lens back to the VIPA generator. In this manner, the apparatus provides chromatic dispersion to the input light.

The pin-hole stop has a pin-hole, provided on an optical axis, for transmitting only strong light beams from a central portion of the light source among the illumination light beams condensed by the condenser lens. The pin-hole stop also has a light reducing/illumination area, disposed around the pin-hole in symmetry with respect to the optical axis, for illuminating the periphery of an on-specimen portion illuminated with the light beams passing through the pin-hole with a quantity of light exhibiting a predetermined ratio to a quantity of the light passing through the pin-hole. The same apparatus also comprises an objective lens for converging the illumination light beams passing through this pin-hole stop on a specimen. The pin-hole stop is located in a position substantially conjugate to a pupil plane of the objective lens.
