5mw 405nm laser pointer must-have for Christmas
It's a square thing, and this is the legendary high powered laser diode itself, about a tenth of a millimeter on each side (see scale on the 100 magnification map). Its upper and lower surfaces are positive and negative. The upper surface is connected to the large copper plate above by a wire, and the lower surface is directly attached to the copper plate below by conductive adhesive. The luminous layer in the middle of this square thing, we can't see. About 0.0001 mm (100 nanometers) thick. The laser diode is a great invention. It developed rapidly within a year or two after the emergence of gas lasers (1960s). Think about it, when gas lasers are meters-long monsters, the cost is high.

Relatively new wireless devices solve all these problems. I mean the wireless demonstrator. You can buy these products from any electronics store and choose from several brands. Software (plug and play drivers) solves the problem of inconsistent mouse clicks. It has a forward and back button, and on all operating systems, according to the needs and expected responses of these buttons. There's also a built-in laser pointer. Unfortunately, in almost all cases, flashers are red, low-brightness laser Pointers.
