From the very first scarry time I fumbled my way through a beam setting, right up to date, I hate the scorch method of beam alignment. I have continuously been looking for a viable alternative, although along the way I have lived with and developed simple logical methods to employ the scorch method. I have had 8 separate attempts at using a red diode beam as dynamic way to ease beam setting. I have also thoroughly investigated beam combiners as an alternative . All these methods are "nearly" but all require the scorch method to set final perfection. They ALL suffer one common practical weakness, it is almost impossible to perfectly match the axis of the laser beam as it exits the tube.........and that has been the achilles heel of this fruitless quest. There are certain valuable uses for such pointers but beam setting and through-the-lens red dotting are not in that list. Instant resetting of a single mirror and demonstrating machine issues , as in this video are great uses for this tool. HOWEVER, because the red beam will never match the laser beam axis, you cannot trust everything that you observe. This video attempts to demonstrate that there is a valuable fault finding use for the tool but that you must not trust the final detail. Exploit its strengths but understand and beware of its weaknesses.
NOTE If you are a real hardened advocate of the coincident beam idea, why not consider the only solution that really works
