In an observation device including a display device, paired ocular optical systems each include a resin lens having a shape defined by an arch and a chord, and provided with a molding gate in an outer peripheral portion of the arc shape, and is appropriately set in: a difference RC between the radius of the resin lens and the length of a line connecting the midpoint of the chord and the point on the optical axis; the diameter D of the resin lens; an angle θ between a direction connecting a midpoint of a long side of the display surface and the point on the optical axis and a direction connecting the molding gate and the point on the optical axis; and an acute angle α between directions connecting the point on the optical axis and the respective molding gates of the resin lenses in the paired ocular optical systems.

A computer-implemented method for displaying augmented reality (AR) content within an AR device coupled to one or more loupe lenses comprising: obtaining calibration parameters defining a magnified display portion within a display of the AR device, wherein the magnified display portion corresponds to boundaries encompassing the one or more loupe lenses; receiving the AR content for display within the AR device; and rendering the AR content within the display, wherein the rendering the AR content comprises: identifying a magnified portion of the AR content to be displayed within the magnified display portion, and rendering the magnified portion of the AR content within the magnified display portion.

The present invention is an optical assembly featuring an architecture which allows adjustment of both objective lenses and the electronic sensing assemblies in the optical assembly. Electrical connections in the housings of the various subassemblies allow focusing adjustment by rotational and/or translational movement for increased adjustability.

A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

Motorized loupes enable the user to automatically increase or decrease the magnification on demand, without touching the loupes. Each loupe has a micromotor attached to it which moves a lens in the loupe to change the magnification. The motor is battery powered and the batteries are carried in a small housing worn by the user. The housing also contains electronic circuitry that at least reads the position encoders, drives the motors, receives the user's magnification commands and charges the battery when plugged in. A cord runs from each loupe to the housing to carry power and signals. The motors are controlled wirelessly by a foot pedal or by voice so that the user does not have to touch the loupes to change the magnification. In the preferred embodiment of surgical loupes, a TTL loupe is attached to each lens in a user's eyeglasses for binocular vision.

A surgical microscope employs a pentaprism beam splitter as a branching unit to branch each beam passed through variable power optical systems into a first beam and a second beam, the first beam being horizontally reflected for an eyepiece unit, the second beam being vertically transmitted for an imaging device. The pentaprism alone is capable of simultaneously conducting reflection to provide an erect image and transmission to provide a photographing image, thereby reducing the number of optical parts in a microscope body of the surgical microscope.

A binocular device for visualizing optical radiation comprises a support structure, a left camera, and a right camera coupled to the support structure. The left camera comprising left optics and a left image sensor, the right camera comprising right optics and a right image sensor, the left image sensor and the right image sensor being configured to create left and right video signals from detected optical radiation received from the corresponding left and right input optics about a same field of view along respective left and right input optical axes. A specular reflection is detected.

The present invention provides a digital loupe device and its automatic view stabilizing method. The digital loupe device is worn or head-mounted on the operator's head via a wearable frame that is connected to a plural of axial rotation modules. A pair of lighting capture modules set on the axial rotation module is used to illuminate the target view and capture the image of the target view in order to send feedback signal. Both the lighting capture modules and axial rotation modules are electronically connected to at least one control unit. The control unit, base on the feedback signal received, moves the lighting capture modules via the axial rotation modules till the desired image of the target view is obtained. The display module connected to the wearable frame can show the captured image and information provided by the control unit.

Lenses are adapted to be attached to existing eyewear or provided as a separate pair of loupes. In an embodiment, different types of lenses are adapted to have zoom features. In an embodiment, prisms are provided that are non-symmetrical Schmidt roof prisms adapted to increase the deflection degree.
