Abstract: An improved illuminator with an adjustable beam pattern to be worn by medical and dental professionals includes a housing, a light-emitting diode (LED) disposed in the housing outputting light through a distal opening in the housing, an achromatic doublet lens mounted in the opening in the housing, and a singlet lens disposed between the LED and the achromatic lens. The distance between the singlet lens and the doublet lens may be adjustable, and/or distance between the LED and the singlet lens may be adjustable, through a threaded connections, for example.

Abstract: A head-mounted light source particularly suited to medical and dental applications includes a base unit with a source of illumination directed through a distal opening in the base unit, and a plurality of interchangeable beam-forming units, each separately attachable to the distal opening of the base unit to produce a different light spot size at a given distance. The preferred embodiment includes a wide-field beam-forming unit, an intermediate beam-forming unit and a high-intensity beam-forming unit, such that the diameter of the spot size progressively decreases from the wide-field to the intermediate to the high-intensity unit. The interchangeable beam-forming units are attached to the base unit through a threaded connection. Each interchangeable beam-forming unit may itself include a distal threaded connection for attachment of a UV or other filter. In the preferred embodiment, the base unit includes a clip adapted for attachment to an ocular mounting assembly.

Abstract: In an ocular support assembly material present in the forward-looking cross-section of the outwardly extending support arms is removed, thereby reducing visual obscuration and enhancing peripheral vision. In the preferred embodiment, the top of each outwardly extending support arm is at or below the middle of the height of the housing, thereby resulting in a low-profile design. At the same time, the support arms are received by the housing with sliding engagement on all sides, thereby eliminating the need for ball bearings or spacers to counteract twisting. The result is a lightweight yet highly stable ocular mounting assembly.

Abstract: A medical/dental loupe assembly provides through-the-lens oculars with an inconspicuous interpupillary distance adjustment capability. The system includes a pair of lenses, each lens having a telemicroscopic ocular cemented therethrough, and an upper portion, one on each side of a wearer's nose. A generally horizontal slot is formed in the upper portion of one of the lenses, and a bridge member connects the upper portions of the two lenses. The bridge member has two ends, one end of which is coupled to the slot through a fastener that may be loosened and tightened, thereby allowing the distance between the oculars to be adjusted and locked into position in accordance with the interpupillary requirements of a user.

Abstract: A compact Keplerian optical system includes a telescope having an image-rotator (Pechan roof prism pair), and an eyepiece and objective lens operative to form an intermediate image plane within the image-rotator, thereby decreasing the overall length. The objective lens optionally forms part of a replaceable cap, and plurality of replaceable caps may be provided, each with a different focal length to adjust for working distance. In the preferred embodiments, the eyepiece includes a singlet and a doublet lens to minimize eyestrain, and the objective lens includes a doublet and singlet field lens operative to increase depth of field and field of view. A practical implementation includes a pair of the telescopes, one for each eye of a user. Such a configuration may take the form of loupes mounted relative to eyeglass frames for surgical, medical or dental viewing applications.

Abstract: An improvement upon telemicroscopic loupes of the type which are adjustably mounted to an eyeglass frame, headmount or through-lens designs. The preferred embodiment includes a cap including an optical element to adjust for the working distance of a loupe. The cap may be frictionally fit onto the loupe or threadably attached to the loupe body. According to an alternative embodiment, one or more eyepiece components may be used alone or in combination with the end cap for adjusting prescription and/or working distance.

Abstract: The entire front portion of eyeglass frames for medical, surgical or dental applications are constructed from a solid piece of machined metal, preferably titanium. This results in no welding of the nose bridge, resulting in a one-piece frame that is substantially more stable than existing designs. In a preferred embodiment, the basic shape is cast or stamped from plate stock from titanium, then machined down, if necessary, to a desired finished product. Holes are provided on the bridge portion for the mounting of medical, surgical or dental optics or other accessories.

Abstract: A heat-dissipating headlamp assembly comprises a housing including a light source such as a light-emitting diode (LED) disposed therein, and a detachable heat shroud covering the rearward portion of the housing. In the preferred embodiment the housing includes a pair of opposing detents, and the detachable heat shroud includes a pair of opposing protrusions that cooperate with the detents to hold the shroud in position. The assembly further includes a mounting bracket extending downwardly from the rearward portion for attachment to a headband, spectacle frames, or other head-worn item, and the heat shroud includes an upper rearward notch to accommodate the electrical cable connected to the light source and a lower rearward notch to accommodate the mounting bracket. The heat shroud is generally cylindrical in shape, and so, too, is the housing, at least where the heat shroud attaches thereto.

Abstract: An ocular mounting assembly for adjustably mounting a pair of ocular devices, such as telemicroscopic loupes, to an eyeglass frame or head mount with linear and rotational adjustments, but with view angle being permanently preset in accordance with working distance. The ocular mounting assembly includes an adjustable ocular support assembly and an adjustable clamp assembly rotatably attached to the ocular support assembly. The ocular mounting assembly includes a housing and two slidable mounting arms to which the ocular devices are attached, the transverse cross-sectional shape of the housing interior and mounting arms being such that substantially all of the volume of the housing interior is consumed apart from close tolerances to facilitate the sliding motion, thus resulting in a structure which cooperates to assist in providing a substantially rigid assembly.

Abstract: Viewing apparatus, for medical and surgical practitioners incorporating one or more optical filters, each exhibiting a reverse photopic response, such that green light is at least partially attenuated, whereas red and blue light are both substantially transmitted. The invention includes means for supporting one or more optical filters in the practitioner's field of view, such as a pair of eyeglass frames or endoscope mounting for use, for example, in conjunction with laparoscopic surgery. Various technologies may be employed to realize a desired reverse photopic response, including absorptive dyes, dielectric layers, and/or holograms.

Abstract: A formable nose pad distributes the weight of eyeglasses and accessories supported by the eyeglass frames over a large area of the wearer's nose. The nose pad has two inner tabs that can be formed to fit the wearer's nose, outer tabs that can be formed to fit the undersides of the eyeglass lenses and a flange through which the nose pad is attached to the eyeglass bridge. Slotted screw holes on the flange allow for height adjustment to fit the height of the wearer's nose.
