Schematic view of a rigid borescope Borescope in use, showing typical view through the device. A borescope (occasionally called a boroscope, though this spelling is nonstandard) is an optical instrument designed to assist visual inspection of narrow, difficult-to-reach cavities, consisting of a rigid or flexible tube with an eyepiece or display on one end, an objective lens or camera on the ...
Because light passes only through the center of the eye's lens, defects in the shape of the lens (errors of refraction) have no effect while the occluder is used. In this way, the ophthalmologist, orthoptist or optometrist can estimate the maximum improvement in a patient's vision that can be attained by lenses to correct errors of refraction. [2]
fine sharp-tipped untoothed forceps for doing a continuous curvilinear incision and removal of the anterior capsule of the lens ("continuous curvilinear capsulorhexis - ccc") •MacPherson's forceps: fine sharp-tipped untoothed forceps with an angulation for holding parts of the lens, the intraocular lens, 10-0 (very fine) sutures, etc.
The profile projector is widely used for complex-shape stampings, gears, cams, threads and comparing the measured contour model.The profile projector is hence widely used in precision machinery manufacturing, including aviation, aerospace industry, watches and clocks, electronics, instrumentation industry, research institutes and detection metering stations at all levels, etc.
Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used in the ...
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
Visual inspection is a common method of quality control, data acquisition, and data analysis.Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of raw human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment.
The hole is then fitted with a cylindrical lens. The lamina is grown in the patients' cheek for a period of months and then is implanted upon the eye. The procedure was pioneered by the Italian ophthalmic surgeon Professor Benedetto Strampelli in the early 1960s.
