Add Christmas lights to the outside of your house
This is Christmas lights http://www.buylaserpointer.com/other-categories/p-166.htmlChristmas lights on the outside of your house might look awesome, but they really aren’t that much fun to hang up. This year, we are using something different—lasers.
Yes, you can now add Christmas lights to the outside of your house with laser pointer Mini 5mW Red . The basic idea is to stick a small device in your yard that shoots lasers at your house to make some spots. These spots then look like little bitty lights. When Christmas time is over, just pick up the laser out of the yard. It’s not quite as bright as your traditional lights, but it’s so simple to set up.
The first element of this device is the laser. I’m not going to talk about Green 1mW Laser Pointer pen today (but I will in the future) except to say the following:They mostly just produce one color of light (and thus one wavelength). So, a red laser creates light with a wavelength of something like 650 nm. We call this monochromatic.
The light produced is coherent. This means that the all the light produced is in phase such that you could think of it as just one wave (with one wavelength).TheLaser Sights for Handguns light is collimated—such that it mostly just goes in one direction with very little beam spreading.
Yes, these are just approximately true—but let’s just work with this for now.So, how do you take one 50mw Green Laser and with it make many spots on your house? The answer is a diffraction grating—which is essentially a device with many super tiny lines on it. It turns out that when a wave (like light) passes through an opening, it sort of re-radiates. We call this diffraction. Suppose I have a plane wave coming to an opening, here’s what that would look like.
A very common problem with laser pointers and lasers in general that is easy to fix is dirty lens. I'll briefly explain the two safest and effective methods to clean laser pointer lens.The equipment used in these instructions are A lasers at buylaserpointer.com .
Safety is always an issue with high power lasers so the first thing you do when cleaning them is take the batteries out. A number of people have had unpleasant accidents cleaning lasers because they left the batteries in.
