The disclosure relates to an eyepiece extender for an ophthalmic microscope, such as a slit lamp microscope. The eyepiece extender comprises certain lens designs and arrangements and provides ergonomic improvement to a user of the ophthalmic microscope and accommodates different magnifications, such as high and low magnifications, while preserving image fidelity for each magnification such that the image is essentially distortion free and color corrected in each magnification instance.

Provided is a snapshot spectral domain optical coherence tomographer comprising a light source providing a plurality of beamlets; a beam splitter, splitting the plurality of beamlets into a reference arm and a sample arm; a first optical system that projects the sample arm onto multiple locations of a sample; a second optical system for collection of a plurality of reflected sample beamlets; a third optical system projecting the reference arm to a reflecting surface and receiving a plurality of reflected reference beamlets; a parallel interferometer that provides a plurality of interferograms from each of the plurality of sample beamlets with each of the plurality of reference beamlets; an optical image mapper configured to spatially separate the plurality of interferograms; a spectrometer configured to disperse each of the interferograms into its respective spectral components and project each interferogram in parallel; and a photodetector providing photon quantification.

Parallel optical coherence tomography apparatuses, systems, and related methods

A reflectometry instrument includes a light source for emitting an illumination beam that illuminates the macula. A portion of the illumination beam is reflected from the macula and forms a detection beam. The detection beam is indicative of macular pigment in the macula. The instrument also includes a first mirror for reflecting the illumination beam toward the macula and for reflecting the detection beam from the macula. The instrument is configured so that the illumination beam and the detection beam remain separated between the macula and the first mirror.

Reflectometry instrument and method for measuring macular pigment

An ocular alignment system for aligning a subject's eye with an optical axis of an ocular imaging device comprising one or more guide light and one or more baffle configured to mask the one or more guide light from view of the subject such that the one or more guide light is only visible to the subject when the eye of the subject is aligned with the optical axis of an ocular imaging system.

Systems and methods for alignment of the eye for ocular imaging

Systems of the present disclosure may include one or more of an optical overlay device, which may include one or more of an imaging optic to receive incoming light from a scene, and project at least a portion of the incoming light onto an imaging sensor; an imaging sensor to transduce into image data the light projected onto it by the imaging optic; a processing engine electrically coupled with a non-transitory computer readable medium having machine readable instructions stored thereon, which, when executed by the processing engine, cause the system to: generate a scaled overlay image based on the image data and a magnification parameter; a display device configured to project the scaled overlay image through a display optic toward a portion of a beam-combiner; a coupling mechanism to enable releasable attachment of the optical overlay device with a primary viewing device.

A combined safety and flashlight includes a frame portion and a housing rotatable with respect to the frame portion. The housing features a plug, a switch, a battery charged via the plug, and a light source powered via the battery and switched on and off via the switch. A compound lens is disposed about the light source and includes a central lens disposed above the light source and configured to collimate light from the light source and an outer lens about the central lens configured to convert light from the light source having a lambertian profile to an isotropic profile.
