Slit Lamp Microscope

  LDX20 Slit Lamp MicroscopeSlit lamp microscope is an ophthalmologic optical instrument used to check preocular and intraocular based on the principle of optical magnification. Making use of the tidy optical slice projected from the slit lamp, the instrument can be used to make accurate examination on the pathological changes, such as cornea, eyelid, front chambers, sclera, iris, crystalline lens and retina. It finds wide applications when fitted with other accessories.

  LDX20A LDX20A slit lamp microscope is modified on the basis of LDX20. It provides more steps of magnification change. Beamsplitter, demonstrator and TV adapter are added between observation unit and magnification changer, which provides the possibility of taking video, teaching and demonstration. Thus, the functions of the slit lamp microscope are extended.Main Specification:
