    en.wikipedia.org/wiki/Slit_lamp

    Eye examination with the aid of a slit lamp. Side view of a slit lamp machine. Cataract in human eye: magnified view seen on examination with the slit lamp. In ophthalmology and optometry, a slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye.

  5. Instrument myopia - Wikipedia

    en.wikipedia.org/wiki/Instrument_myopia

    When someone looks into an optical instrument, such as a microscope, vision is far from ordinary. A microscope might force the person to use only one eye, it presents the person with a limited field of view, it presents a magnified view, and it allows the person to adjust the focus of the instrument for any viewing distance. Ideally, the person ...

    en.wikipedia.org/wiki/Human_eye

    The eyes sit in bony cavities called the orbits, in the skull. There are six extraocular muscles that control eye movements. The front visible part of the eye is made up of the whitish sclera, a coloured iris, and the pupil. A thin layer called the conjunctiva sits on top of this. The front part is also called the anterior segment of the eye.

    en.wikipedia.org/wiki/Traveling_microscope

    A traveling microscope. E—eyepiece, O—objective, K—knob for focusing, V—vernier, R—rails, S—screw for fine position adjustment. A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm.

    Under ideal conditions, this produces an "hourglass" shape of this point source in the third (axial) dimension. This shape is called the point spread function (PSF) of the microscope imaging system. Since any fluorescence image is made up of a large number of such small fluorescent light sources, the image is said to be "convolved by the point ...

  9. Pupil function - Wikipedia

    en.wikipedia.org/wiki/Pupil_function

    The pupil function or aperture function describes how a light wave is affected upon transmission through an optical imaging system such as a camera, microscope, or the human eye. More specifically, it is a complex function of the position in the pupil [ 1 ] or aperture (often an iris ) that indicates the relative change in amplitude and phase ...
