Laser output calibration tab

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.
