what would you like to know about me? i posted a wtb on the wtb/wts forum.. yes im new, been into lasers for a while, i was recommended this site by a friend who is also into lasers. is my member name offensive? i like it as i find it quite hilarious, not meant to offend.
asking for 532nm at that power as i beleive it will be most visible. its needed for a target system we have at a local rifle range that is triggered by light, its got a tiny sensor on it though and the whole system is under a roof/hut sort of thing, so even in broad daylight, it hardly gets triggered. would like a strong laser to activate it at the range. we shoot from 1 mile up to 1.5 to 2miles. if any more info is needed, let me know.
it doesn't need to be a tiny spot. i need to hit a sensor that is around 10 inches x 10 inches in size, so quite a large plate for a sensor, just need enough focused light to hit the plate to trigger it, a nice focused beam would be helpful though im sure
coincidence is that I have a pointer doing that, I can sell it to you, but I need to know what the minimum light intensity that the sensor can operate
Edit: prices of green pointers are not cheap, with power 1w, price is more 200$
And that is for 520 nm using a higher divergence direct to wavelength laser diode, 532 nm DPSS and you will pay a fair amount more and that’s for an unstable ~800 milliwatts, a lot more $ for a stable DPSS at over a watt.
If you don’t mind a fatter beam diameter, I agree, just add an expander if 2.6 mRad using a 6 mm diameter lens is too high, or have one built for you using a larger diameter longer focal length lens and you achieve lower divergence at less loss without adding more glass. Trinh can build one using a 3 inch diameter PCX lens soon. Maybe a NUBM44 7 watt blue with a beam expander on it might be more to your liking?
I hadn't seen that, I don't see them listed now. Do you have a link to what they were, has anyone verified their stated output and checked stability? If I had seen that listing, I would have purchased it, that is a far, far lower price than I've heard of before for that amount of DPSS power.
Since he doesn't have them now, I wonder if they make that model anymore and why the price so low. I've asked Jetlasers if they would find an unusually high output PLE-Pro, but they never came through, I was hoping to find a 1200 mw DPSS 532 nm pointer at the price of a PLE-Pro, have never seen a 2 watt 532 nm pointer anywhere yet, I think there was one manufacturer making a high power DPSS 532 nm pointer which may have approached it though, can't remember the company name, it wasn't cheap..
I just prefer a DPSS due to the smaller beam diameter at a decent amount of divergence compared to an expanded 520 nm pointer, I have two expanded 520 direct to wavelength laser diode pointers, one expanded to 30 mm, the other expanded to 125 mm.
