摘要： An illumination device of the invention is an illumination device 100A including an ellipsoidal reflector 130, an arc tube 120, a sub-mirror 122, and a parallelizing lens 140A, which is characterized in that on a light incident-surface 140Ai of the parallelizing lens 140A is formed a reflection reducing layer 142A optimized to match with a light, which is, of the lights emitted from a luminescent center P of the arc tube 120, a light that is emitted toward the ellipsoidal reflector at any angle of 60° to 80° with respect to an illumination optical axis 100Ax and goes incident on the light incident-surface 140Ai of the parallelizing lens 140A after the light is reflected on the ellipsoidal reflector 130. The illumination device of the invention is thus able to further improve efficiency of light utilization as well as further reduce unwanted stray lights by further reducing overall reflectance of the light incident-surface or the light exiting-surface of the parallelizing lens. A projector of the invention, by including the illumination device capable of further improving efficiency of light utilization as well as further reducing unwanted stray lights, serves as a high-intensity, high-quality projector.

摘要： The invention provides an illumination optical system and a projector that can efficiently utilize light from a light source by causing light from the light source reflected by an elliptic reflector to pass through the corresponding cell lenses of first and second lens arrays. The illumination optical system causes at least light beams in a center portion around a light-source optical axis, of reflected light reflected by an elliptic reflector, to pass on the optical paths extending slightly outward relative to the optical path parallel to the light-source optical axis, like the light beams, so that the light beams pass through the corresponding cell lenses of a first lens array and a second lens array.

Furthermore, there is provided a quasi-signal WDM which wavelength-division-multiplexes the first and second quasi-signal lights having a wavelength shorter than the wavelength band of the WDM light and a wavelength longer than that with the WDM light and which puts the light in the optical amplifier. On the output side of the optical amplifier, an wavelength division multiplexer is arranged, and a first amplified quasi-signal light and a second amplified quasi-signal light are taken out of the amplified signal light respectively, and optical output levels thereof are detected, and the attenuation amount of a variable attenuator is controlled so that the levels of both may be approximately the same, and the gain of the optical amplification imposed on the optical amplifier is controlled. The optical amplification can be performed in the state where the degradation of the gain flatness of the optical amplifier itself caused by the change of the ambient temperature or the like is prevented and the gain uniformity between each signal light of the WDM light is kept.

摘要： Disclosed is an apparatus for measuring particles or particulates in a fluid in a measuring cell provided with a measuring window through which a laser beam is projected or through which light scattered from the particles passes. The surface of the measuring window is spherical with a radius of curvature whose center is at a point on which the laser beam converges for measurement. With this arrangement, light focused on the convergence point or light coming from the point always passes through the interface between the window and the fluid in the cell at an angle that is normal thereto. Thus no reflection of the light passing through the window occurs at the interface with the result that fluctuations of the refractive index of the fluid in the cell do not effect the focusing point of the light.

摘要： An apparatus for detecting ophthalmic diseases such as an inflammation in a patient's eye which includes means for focusing a laser beam at a selected spot in the eye. The light scattered from the eye is photoelectrically detected and converted into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection in the patient's eye. The laser beam is deflected vertically and horizontally. The electrical signal derived from the vertical scanning is compared with the other electrical signals from the horizontally shifted scanning of the laser beam to remove noises from the electrical signal.
