This is a 1mW green laser pointer for use in a smaller room for presentations. The 5mW can be a bit overpowering in a conference room setting. It is actually a 5mW unit that has been adjusted down so that it stays below 1 mW in power. It is still brighter then even our best 635 nm red pointer.
This pointer has a negative feedback circuit (APC = Automatic Power Control) that insures that the output power will not exceed 1mW. This makes them more suitable for indoor use.
It has a small green LED placed just above the "ON" button to show when the pointer is radiating.
This is not a toy - not for children.
All metal construction.
Metal gift box. 2AAA batteries included.
A glass collimating lens causes the "dot" to be sharply defined.
This pointer is NOT MADE IN CHINA. It's made in TAIWAN!
The APC pointers have a negative feedback circuit (APC = Automatic Power Control) that insures that the output power will not exceed 1mW. This makes them more suitable for indoor use. It has a small green LED placed just above the "ON" button to show when the pointer is radiating. You need to start with a unit that has a nominal output of say 10-15mW and incorporate a sensor after the MCA and send a voltage back to the driver circuit that will establish a "setpoint" that represents a certain output level. The driver circuit then adjusts the current to the pump diode to achieve that level. This is in addition to the photodiode that is in the pump diode assembly itself which is used to keep the pump diode from going crazy (chaotic non-linier device that it is). An additional benefit feedback with headroom has is that the device is no longer subject to the "cool-down" rule and may be kept on continuously
