Approximately 9.6" long overall. Works perfectly. 'Laser Drive' power supply accepts 10 - 14vdc input and can be powered from any 12vdc power supply or battery. Emits a brilliant red beam. With proper collimation using common lenses available anywhere who knows what range you can get. Perhaps several miles.
Bought this from a surplus house to use in a holography project that never got off the ground. Too many things to do and too little time.
What can it be used for? Use your imagination. Light show? Holography? Collimation? Cool on really foggy nights! Blows those wimpy laser pointers away for brightness. Unsure of power output.
Probably somewhere between 2 to 4 milliwatts - I could be wrong but I doubt it'd be more. I'll include complete hookup instructions.
Will trade (shipped) for one of the following:
1. A compatible 1.25" visual back for the ETX-90 + $20
2. Meade #825 RA finder for ETX-90 + $5
3. Meade #932 45° Erecting Prism for ETX-90 + $5
4. Or make a shipping included cash offer
MUST READ THIS WARNING:
This can be a DANGEROUS device if you are not careful. Although it will not catch anything on fire, instant and permanent blindness can occur if your eye is directly exposed to the beam or indirectly exposed to the beam from reflections off shiny surfaces - Especially
after a precise collimation. Your retina can be permanently and irreversibly damaged without any pain whatsoever! I highly recommend proper laser goggles. Also - the power supply produces DANGEROUS voltages on it's outputs even though powered from batteries - it could KILL YOU if you are not careful! At the very least it'll knock you across the room!
I will not and can not be held responsible for it's misuse!
