An insert for guiding and orienting a surgical laser peripheral into a calibration device for calibrating the laser's output is disclosed. This insert is affixable to the output end of the laser peripheral. It is configured as a rigid body of flat sheet stock shaped at its lower end to permit insertion into the aperture of a laser calibration device. It has at its midsection a shoulder which limits insertion into said aperture to a predetermined depth. It has, at its upper end, one or more manually-engagable tabs for manipulating the insert with the peripheral attached. A calibratable laser peripheral which is made up of the peripheral in combination with such a laser calibration insert is also disclosed.
A fiber optics calibration system (10) incorporated into a laser surgical system (12). A laser light source (14) produces a light beam (16), a portion of which is directed by a first beam splitter (18) into a radiation detector (26) and a further portion of which is directed by a safety detector (28) into a safety detector. A safety shutter (31) is interposed between the radiation detector (26) and the safety detector (28) and controlled by the safety detector (28). During calibration, the light beam is directed through a fiber optic cable (24) and then through a calibration adaptor (34) and calibration receptacle (36) a via a light pipe (38) to the safety detector (28). A calibration switch (40) locks out operation of the safety shutter (31) such that readings of the radiation detector (26) can be compared to those of the safety detector (28) and compensation from an expected standard value be made therefor by a controlling computer (42). In a preferred embodiment, the proximal end of the fiber or delivery device is a signature connector (23) which is uniquely recognized by the output port (22) as the proper fiber for the laser console (12). The calibration adaptor (34) is preferably adapted with appropriate internal and external contours to be complementary to the laser light output tip (33) of the fiber and to the internal contour (35) of the calibration receiver port (36). These features insure the correct fiber is employed with the console for which it was designed and helps prevent reuse of FDA cleared "single use only" fibers and delivery devices.
An alignment cross hair apparatus for partially eclipsing a laser beam includes a laser generator that emits a laser beam. A frame includes a pair of members that cross one another at an intersection within the frame. The frame is attachable to the laser generator in such a manner that the intersection of the members is within the laser beam so that the laser beam is partially eclipsed by the pair of members.
A device for testing the light power output of an optical system comprises a thermochromic element, a body element optionally providing collimation or other means of reproducible positioning, and optionally filters and attenuation. A preferred device fits onto the end of an optical power delivery system, and the thermochromic element changes color if the system output is above a defined threshold. An alternative device provides a flat target with a The device may be adapted to be sterilizable, and may be disposable. Optional means for ensuring that the light delivery system is operational during the measurement are provided.
