    摘要: A filter and method for filtering an optical beam are disclosed. One embodiment of the filter is an optical filter for filtering an incident light beam, comprising an optically effective material characterized by: a light transmittance of less than 1% for wavelengths below 420 nm; and a light transmittance for wavelengths complementary and near complementary to wavelengths below 420 nm that, combined with the transmittance for wavelengths below 420 nm, will yield a filtered light beam having a luminosity of about 90% and an excitation purity of 5% or less. The complementary wavelengths can be wavelengths above about 640 nm, wavelengths above about 660 nm, and/or wavelengths from about 540 nm to about 560 nm. Further, in one embodiment the difference between the light transmittance just below 420 nm and the light transmittance just above 420 nm can be greater than 90%. Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined.

The optically effective material can be optical-grade glass, an optical-grade plastic or polymer, a thin-film dielectric coating, or an optical-grade glass or plastic coated with a dielectric coating. The optical filter can be mounted downstream of an illumination source exit aperture, wherein the illumination source produces the incident light beam, and upstream of a site to be illuminated by the filtered light beam. Alternatively, the optical filter can be operably mounted on a set of viewing optics of a surgical microscope to filter a reflected portion of a light beam produced by an illumination source and used to illuminate a site, such as a surgical site.

    摘要: An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patient's eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.

    摘要: A macular pigment reflectometer is handheld, light, and portable. It can be provided as a part of a self-contained system. The self-contained system includes a docking station in which the macular pigment reflectometer is placed between uses. The docking station is used to recharge the battery of the handheld macular pigment reflectometer. The docking station also has one or more types of communication ports, such as one for a wired or wireless internet connection, through which the handheld macular pigment reflectometer can communicate with a computer or an electronic medical records system. The instrument operates in a pulsed operating mode wherein relative instrument-to-eye motion is reduced and, preferably, nearly eliminated. The handheld macular pigment reflectometer contains an on-board spectrometer which is designed to capture spectra in very short intervals of time. A trigger on the instrument allows for a rapid, intuitive, and sequential alignment followed by rapid data gathering.

    摘要: A continuous high resolution fluid level monitoring system is provided by embodiments of the present invention. This continuous high resolution fluid level monitoring system includes a unique fluid level sensor having a point light source, parabolic reflector, sensor array, and detection, processing and control system. The point light source illumines a parabolic reflector wherein the point light source is located at the focus of the parabolic reflector. The parabolic reflector reflects light from the point light source to produce a parallel light curtain. This parallel light curtain is parallel to an axis of symmetry of the parabolic reflector. The parallel light curtain illumines a chamber such as a chamber in an ophthalmic surgical device used to contain surgical fluid. The sensor array coupled to the chamber detects the parallel light curtain illuminating the chamber. The sensor array provides an output to a detection/processing/control system in order to determine the fluid level within the chamber. This optical method of determining the surgical fluid levels may be advantageous in that it prevents physical contamination of the surgical fluids.
