The RF emitter is embedded with a wireless RF emitter
On another note, what I'd really want would be a combined laser pointer with a "burning" laser. I could then get a lock on a small target (a cockroach or a fly sitting still), then activate the burning laser to kill it. Burn the insect when the DVD laser kicks in for some predetermined time.Many invertebrates, including insects, are unable to see red light, and so are not disturbed by a red laser pointer.You know what's funny, my uncles company is working on a laser mosquito killer for Africa!
Even if not as good as a helium-neon laser in the areas of coherence and stability, for many applications, laser diodes are perfectly adequate and their advantages - especially small size, low power, and low cost - far outweigh any faults. In fact, these 'faults' can prove to be advantageous where the laser diode is being used simply as an illumination source as unwanted speckle and interference effects are greatly reduced.
Like their IR cousins, the typical maximum power from these devices is around 3 to 5 mW. Cost is in the $10 to $50 for the basic green laser pointer diode device - more with optics and drive electronics. Higher power types (10s of mW) are also available but expect to spend several hundred dollars for something like a 20 mW module. Very high power diode lasers using arrays of laser diodes or laser diode bars with power output of WATTs or greater may cost 10s of thousands of dollars!
The remote control Red Laser Pointer is composed of a RF remote control and a receiver (a USB interface). The RF emitter is embedded with a wireless RF emitter, when using it; we only need to insert the receiver into the USB interface of the computer case.The remote control laser pointer will work smoothly without installing a drive. Users can manipulate the receiver by clicking the related functional keys on the RF remote control.
As the video demonstrates, a laser of this power (around 250 mW) is not a toy. While you certainly must keep others safe, you the experimenter may have the largest risk. Most laser eye injuries happen to the laser experimenter or user. And it takes only one stray reflection to cause a permanent blind spot.As it should be, pointers figures prominently in the laser pointers, which mainly include red ray pointers and green ray pointers.
