Basic electrical knowledge and skills are required for setup and operation of this device. This product may not be suitable for everyone. Reverse polarity, excessive current and high heat will damage or ruin these.Because the NUBM44 laser diode is a multi-mode diode you will always get a rectangular spot as opposed to a circular dot. This is a characteristic of multi-mode laser diodes.
The closer you can get the lens to the work the smaller that rectangle will become and the finer the detail you can achieve. You want to focus it so you have the cleanest and thinnest line possible.Don't try to make it symmetrical or you will produce a larger and less powerful spot. Be aware that the closer you get it to the work the more likely you are to get smoke and/or soot on the lens. A secondary air assist fan will greatly help reduce that risk. If you do get smoke on the lens the spot will start to look blurry.
It can be cleaned with a very soft lens cloth and some 91% rubbing alcohol. This is a very powerful device and you must never shine it at another person, animal, aircraft or another persons property. This is NOT a toy!
You are solely responsible for it's use. Always wear protective eye-wear that is rated to block the 400-470nm wavelength and NEVER look directly at the beam. You only have one set of eyes! Once your order is placed it will go out right away because I don't want you to have to wait any longer than you have to.
