[Laser] And furthermore

Sat, 27 Dec 2003 23:51:56 -0600

With the laser pens that I got in the kit, all you need to do is unscrew the "bullet" style cap (silver on mine).  Under that you will see an adjustable lens that is made for a large flat screwdriver.  Try screwing that in and out--it will adjust the distance between the lens and the diode to give you a tighter spot.  Make sure you don't use too small of a screwdriver lest you scratch the lens.
