Instead of looking for a 200mW green laser pointer, I bought this one. I accidentally dropped it on the concrete floor a few times and the effect was very noticeable. I don't recommend intentionally careless use of the high power laser pointer, but don't worry if you happen to drop it. I realize there's a world of difference between laser pointers and how much light you can get out of them, but I'd prefer to have a regulated circuit device. I like the fact that it has strike dials on the front and back. It's nice to have it at hand. You can use a laser to engrave letters. You can engrave letters at high temperatures from a laser. The light output of the high-power blue laser pointer is divided into 4 stages, 1. The light is weak when pressed. 2. Press Strong light twice. 3. Press and hold for a while to make it glow. Four. Press it again to turn it off. The tail cap has a safety lock.
A laser pointer is used to drive away crows
Laser pointers can also be used to repel crows. It's easy to use and no crows come. Since it is a standard product, I can use it with confidence. I've been using it for 3 years and it works fine. Countermeasures against crows Lasers drive crows, for green laser pointers, DPSS (diode-pumped solid-state laser) products have become cheaper and more popular, but due to the large number of parts as optical devices and the complexity of electronic circuits. In general, it tends to be more expensive than a pen laser pointer. Depending on the product grade (price range), there are differences in output stability and shock resistance when dropped.
The laser pointer has a good presentation effect
I decided to do a demo in-house and thought it would be nice to have a blue laser pointer. It's not just a laser pointer, it's just a PowerPoint, but it's nice that pages can be advanced and, most importantly, rechargeable via USB (annoying when the battery dies). I don't know how long the battery will last, but I think you'll be happy with the price. 50000mw laser pointer is super strong: the working principle and application of a powerful laser pointer: the laser pointer emits a laser is a device that can be ejected. According to the different working medium, it is divided into four types: gas laser, solid-state laser, semiconductor laser and dye laser.
