I have a 5mW red laser pointer with a little blue LED mounted on a pen. I had not used it much but for school presentations, but now that in Physics class we are going over light, reflections, and refractions, I've been using it everyday for a week and it has inherently been jostled around a lot more than it is used to. My school, for some strange reason, does not have laser pointers.
I will be the first to admit that I don't know as much as most when it comes to lasers and their hardware, so if you could please bear with me. This is also my first post here, and I don't want to be going against the grain on anything.
Up until this afternoon, the laser pointer was just that: a pointer. Now, it is more of a laser look-in-this-general-vicinity-and-maybe-if-you're-lucky-you'll-see-what-I'm-trying-to-show-you. The projection is still a sharp circle with the brighter stripe in the middle as it always has been, but now it take up a good 16 square inches on a wall 30 feet away.
I might think it would be the hardware, but as previously stated, this is not my cup of tea (not that I don't want it to be. I just don't have the funds or knowhow). I'm not sure if this is a common problem with an easy fix or not. It's a good pointer and has been good to me, and I would prefer not to have to turn it into some illegal YouTube-enlightened experiment (not yet, anyway).
If someone out there could please give me some advice, that would be great.
I'm glad I found this place. I have wanted to learn more about (read: play around with a purpose) with lasers when I had the time, and I should this summer, so I'm sure this forum will be a great resource for me in the future.
