The disadvantage of these methods is that they are not easy to use with tools such as power drills or similar, and usually only allow calibration in one plane, that is, either in the vertical plane or in the horizontal plane, but not both internal calibration

An alignment apparatus for aligning a device, such as a tool or other implement, at a desired angle with respect to a flat surface, comprises a light source for generating a beam of light and means for splitting the beam of light into a plurality of beams for projection onto the surface. The plurality of beams form a pattern of markers or indicators on the surface which changes if the orientation of the apparatus with respect to the surface changes. The apparatus is particularly suitable for aligning a drill or other tool with a wall or other flat fixture.
Description
technical field [0001] The present invention relates to a calibration instrument and more particularly, but not exclusively, to an instrument for calibrating an implement, such as a tool or other instrument, to a desired angle relative to a planar surface. The invention also relates to a method and apparatus for refracting light, in one embodiment of which a single light beam is split into a plurality of beams which define discrete points and / or or a straight line. Background technique [0002] There are many instances where it is desirable to calibrate an object to a predetermined angle relative to a planar surface. An example is the alignment of a hand-held tool such as a drill or similar to a wall or other fixture. Generally, it is desired that the drilled holes for mounting screws or the like are substantially perpendicular to the wall. Miscalibrated drills can make installing these parts more difficult, and can even cause injury if a miscalibrated drill drills into a...
