Abstract: A vaginal speculum apparatus includes a portable illumination assembly that is releasably attached to one of the upper blade and lower blade of a disposable vaginal speculum. The portable illumination assembly is defined by a housing that retains at least one LED and a portable power supply. The portable illumination assembly can be energized by an externally accessible member after the illuminator has been attached to the speculum.

Abstract: A system for determining refractive eye aberrations includes an optical arrangement having a first conjugate lens having an effective focal length (EFL) of about 150 millimeters and a second conjugate lens having an EFL of about 88.9 millimeters. The first and second conjugate lens are each positioned in a housing along a return light path and are separated by a distance of about 238.9 millimeters. The arrangement enables a range of measurable diopters of an eye to be between about ?10 diopters to about +10 diopters.

Abstract: A diagnostic instrument includes an illumination system for providing illuminating light and an imaging system for directing the illuminating light to a target and for transmitting light reflected from the target to a viewing location. The imaging system includes an electrically controllable variable focus liquid lens assembly for focusing the light reflected from the target at the viewing location. The liquid lens assembly includes at least one liquid lens including a housing filled with a first liquid, and a drop of a second liquid being in contact with the first liquid in a predetermined form. The lens further includes a first electrode insulated from the second liquid and a second electrode in electrical contact with the first liquid. A variable voltage control selectively applies a voltage to the first and second electrodes to vary the focus of the lens. An electronic imager is provided to capture the reflected target image.

Abstract: A metal halide arc discharge lamp is disclosed having a power input rating of not more than 35 watts. The lamp includes an envelope of light transmissive material, such as fused quartz, including a bulb portion, a pair of transitional neck portions extending from the bulb portion, and a pair of stem portions extending from the transitional neck portions respectively. The bulb portion of the envelope defines an arc chamber therein and has an external surface area of such value as to produce a wall loading not exceeding 35 watts/cm.sup.2. The arc chamber contains a fill of mercury, inert gas and metal halide. The mercury and the metal halide are adapted to substantially vaporize during operation of the lamp. A pair of electrodes extend into the arc chamber from the pair of neck portions respectively. Each electrode has an electrode tip spaced apart from one another by a distance A within the arc chamber. The neck portions of the envelope each have a wall surrounding a segment of one of the electrodes.
