A universal gonioscope-contact lens system suitable for both diagnostics and / or intraocular laser surgery that consists of a conical gonioscope body with a plurality of mirrors on the inner side of the body and a contact lens that consists of a contact lens portion intended for contact with the patient's eye cornea and a rear main optical portion that may have any arbitrary shape, provided that it has beveled flat surfaces arranged perpendicular to the beams reflected from the gonioscope mirrors. The aforementioned rear main optical portion can be conveniently used for manipulating the contact lens and for arranging optical lens components such as a concave lens and convex lens. The convex lens component may be used for focusing a laser beam, while the flat areas and the concave lens can be used respectively for delivery and diverging of the illumination light. The contact lens portion can be made from a material softer than the main optical portion. The entire assembly can be disposable as a whole or the contact lens portion may have disposable soft inserts attachable to the front end of the contact lens and selectively used to match the curvature of the patient's eye cornea.

A micro flow control capillary electrophoresis liquid core waveguide fluorescence detector includes a liquid core waveguide capillary, a laser light source, a photodetector, a high-voltage power supply, an electrode, a liquid storage container, a sample tube, a pinhole diaphragm, a filter and a shadow shield; the device makes use of a liquid core waveguide phenomenon and uses the same liquid corewaveguide capillary as a capillary electrophoresis separation channel and for fluorescence signal transduction. In the invention, the light given out by the laser light source can be not focused by alens but directly radiates on the liquid core waveguide capillary through the pinhole diaphragm; the fluorescence led out by the outlet port of the liquid core waveguide capillary can not be collectedbythe lens but directly enters into the photodetector through the filter. The liquid core waveguide capillary is taken as a micro flow control capillary electrophoresis separation channel and an optica l conduction channel, so as to furthest reduce optical elements, simplify an optical system, make the structure more compact, so as to provide a feasible technical route for developing miniature microflow control analytical instruments.
