Abstract: An optical connector with memory function comprises memory function for storing respective identification information in order to readily and exactly perform separate control of respective control steps and further to obtain convenient handling of connectors. The optical connector with memory function 3 of the present invention is characterized by a memory function capable of untouchably performing, from outside thereof, writing-in and reading-out of necessary information. The memory function has a structure mounted on or mountable on the outer construction of a housing accommodating therein the optical connection portion of an optical connector plug in the optical connector with memory function.

Abstract: A non-lock detector switch is provided on or near an adapter to be switched by a connector plug when the connector plug with memory function unit is coupled to the adapter having an antenna for accessing to the memory function unit. Accordingly, connection state of each connector can be directly and simultaneously detected by the switching operation of the detector switch at a time preceding a little from a time when the antenna detects the memory function unit just having closed to a position opposed to the antenna. This is useful for exactly and detecting without delay the complete coupling state of each one of a number of adapters in distinction from the incomplete coupling state of any one of adapters.

Abstract: A laser treatment apparatus for performing treatment by irradiating a part to be treated by a laser beam for treatment is disclosed. This apparatus includes a laser source which emits the treatment laser beam; a multi-articulated arm for delivering the treatment laser beam emitted from the laser source, the arm including a plurality of light delivery pipes at least one of which is axially extensible, a joint part for jointing the light delivery pipes, the joint part being rotatable with respect to at least one of the pipes jointed by the joint part, a reflection mirror disposed in the joint part; and a hand-piece connected to an end of the arm and used for irradiating the treatment laser beam delivered therein through the arm to the treatment part.

Abstract: A laser treatment apparatus providing a slit-lamp microscope with which an eye of a patient is observed, a box unit which is provided with an optical system to deliver a laser beam inside an observing visual field of the slit-lamp microscope, an attachable device which mounts the box unit on the slit-lamp microscope, and an optical fiber through which a laser beam for ophthalmic treatment is delivered to the box unit, wherein the box unit is provided with a dichroic mirror having characteristics of reflecting the laser beam for treatment to the patient's eye while absorbing a therapeutic surgery laser beam being incident to the dichroic mirror.

Abstract: A laser apparatus for ophthalmological operation which can be readily handled and moved extremely easily. This apparatus comprises: a laser light source; a microscope unit with an observation optical system for observing an eye to be operated; a laser light guiding optical system for guiding treatment light emitted from the laser light source toward the affected part of the eye to be operated within an observation visual field of the microscope unit; a power source housing for containing a source for supplying electrical power to the microscope unit and the laser light source; conductor cables for connecting the microscope unit and the laser light source to the power source; a base with a friction plate which can be attached to the top surface of the power source housing; and a slide device which includes a joy stick and slides the microscope unit with respect to the base by operating the joy stick.

Abstract: An optical ophthalmic treatment apparatus comprises: a slit illuminating light beam projecting optical system having a reflecting member for reflecting a narrow illuminating light beam toward a patient's eye to illuminate the patient's eye; a stereomicroscopic observation optical system for observing the patient's eye; a first therapeutic light beam projecting optical system for introducing a first therapeutic light beam through a position on the side of an operator with respect to the reflecting member into the stereomicroscopic observation optical system; a light path deflecting optical element capable of being inserted in and retracted from a plane including the light paths of the stereomicroscopic observation optical system, of transmitting at least part of the narrow illuminating light beam and of reflecting a second therapeutic light beam; and a second therapeutic light beam projecting optical system for projecting the second therapeutic light beam which is reflected toward the patient's eye by the ligh

Abstract: An ophthalmic laser apparatus has a proper exit angle from a probe to prevent a sclera from being damaged when the probe is used to treat an eye of a patient. A laser beam emitted from a laser oscillator is directed to a light cable receptacle connector by an optical system. The laser beam is directed to a delivery optical system or a probe by a light cable having a connecting part at one end thereof to be connected to the light cable receptacle connector. The probe is bent near an end thereof and the end of the probe is generally spherically shaped.
