Abstract

An alignment tool 1 is adapted to inject a laser beam into a spectromet for aligning components therein. Mechanical and electrical interlocks, described below, prevent operation of the laser except when tool 1 is properly inserted into the spectrometer.

Laser Alignment Tool with Interlocks

An alignment tool 1 is adapted to inject a laser beam into a spectromet for aligning components therein. Mechanical and electrical interlocks, described below, prevent operation of the laser except when tool 1 is properly inserted into the spectrometer.

Tool 1 includes a cylindrical housing 2 enclosing a laser to which electrical power is delivered through a power cord 3. A secondary housing 4 encloses a normally open reed switch connected in series in cord 3. A plate 5 mounts housing 4 on housing 2. When tool 1 is placed in a spectrometer, a magnet (not shown) located therein closes the switch. Upon removal of tool 1, and commensurate movement of the reed switch away from the magnet, the switch opens, thereby interrupting any power to the laser.

One end of housing 2 is of a reduced diameter and has a bore 6 through which the laser beam passes. A spring shutter 7 is mounted on housing 2 and has a tip portion 7a provided with a hole therein. Upon insertion of tool 1 into the spectrometer, spring 7 is compressed or moved so that the hole in tip portion 7 is in alignment with the laser beam. The beam thus passes through and is reflected from a surface 8 into the spectrometer. Upon removal of tool 1 from the spectrometer, shutter 7 moves so as to cause the hole to be moved out of the path of the laser beam, thereby mechanically preventing any beam from exiting the tool.
