Small round dot laser

[Ron N]

Does any one know where I can get a small round dot laser ?
I have a project that I need to project a very small dot across a
distance of about 10 feet. This device I am working on needs is used
to measure Alinement so accuracy is important.That is the reason for the
small dot. Most lasers I have sean so far all produce a small angle line that they call a dot. Cost is also important Size of the laser device needs to be very small also I will be attaching it to my system so the pen lasers will not
work.

Your best option for alignment lasers are HeNe lasers. You can often find them on ebay cheaply. They produce a small perfectly round dot.
