| SPECIAL FEATURES | SLIT LAMP IS A NON-INVASIVE DEVICE THAT IS ABLE TO ILLUMINATION, MAGNIFICATION AND OBSERVATION THE HUMAN EYE; MAGNIFICATION 10X AND 16X; 3 X AA NI-MH BATTERIES. OPHTHALMIC DIAGNOSTIC INSTRUMENTS DESIGNED FOR EXAMINING THE EYE (MOSTLY THE ANTERIOR PART OF THE EYE) USING AN ILLUMINATION SYSTEM COMBINED WITH A BINOCULAR MICROSCOPE. THE INSTRUMENTS USUALLY CONSIST OF ILLUMINATION SOURCES WITH A MECHANISM THAT PROVIDES A SLIT BEAM OF LIGHT INTO THE EYE WITH DIFFERENT TYPES OF ILLUMINATION (E.G., DIRECT OR INDIRECT, FOCAL OR DIFFUSE, BACKGROUND ILLUMINATION), A BINOCULAR MICROSCOPE FOR VIEWING THE MAGNIFIED SLIT IMAGE, AND A CONTROL COMPONENT FOR ADJUSTING THE FOCUS OF THE MICROSCOPE AND THE SLIT (E.G., SLIT ROTATION, SLIT WIDTH); SOME ALSO HAVE REFRACTION MIRRORS TO DIRECT LIGHT TO A CAMERA MOUNTED ABOVE THE MICROSCOPE. SLIT LAMPS PROVIDE A MAGNIFIED VIEW OF EYE STRUCTURES (E.G., EYELID, SCLERA, IRIS, CRYSTALLINE LENS, CORNEA). |
