I just got my RPL-325 replaced, and upgraded to this higher power model. Thanks Jack for the major hookup, and on time!!
After initial tests, this laser exceeded all my expectations. And I'm picky.. ask Jack if you don't believe me.
Here are some quick specs I measured today.
Divergence: not more than 1.1mRad. (still testing this with different power levels and filters)
Power:
Tested with Coherent LaserCheck
With freshly charged battery:
1-15sec samples = 405-420mW
15-30sec samples = 430-470mW
30-90sec samples = 440-499mW (wouldn't touch 500mW )
Then it dropped to 370-388mW as I continued measuring for another 2 minutes.
Body didn't get warm after that test.
After about 30 minutes of short ON and OFF times that tired the battery a bit, I measured it two more times with about 5 min OFF in between. Both tests were about the same.
1-15sec sample = 370-405mW
15-30sec samples = 380-390mW
30-90sec samples = 368-380mW .. where it stayed till I stopped measuring at 180sec.
After that third test body started to feel slightly warm.
Test (level5) - later date (fresh battery)
I just did another quick test with different fresh battery. A bit different results but still more than positive surprise.
0-1min 380-420mW
1-2min 360-390mW
2-3min 408-440mW
4-5min 370-415mW
5-6min 338-390mW
On level #1 it outputs 150-160mW. (with good battery)
100-120mW with used battery.
Test #2 (level 1) - later date (used battery)
0-1min 105- 115mW
1-3min 110-118mW
3-5min 110-122mW
5-8min 115-125mW
8-10min 115-125mW
10-12min 120-130mW
12-15min 130-150mW
15-18min 125-130mW
19-21min 118-121mW
22-25min 108-113mW
What amazes me the most is that there is no visible beam instability at any moment in the first 3 min. You know the usual initial "flicker" Not even during first few seconds warmup. Very nice.
Also, I noticed something not that important, but very admirable to me.
Beam output is almost perfectly in-line with centerline of the laser body. I LOVE that. Its better than any unit I ever had or seen. Must be one in a hundred that is this well placed.
Projected dot is nice and round. No scatter. I check that at distance shooting right next to edge of the wall.
My previous unit had irregular dot that kept changing shapes on a small scale. Everything else was great though and it took me a while to make up my mind to send it back.
The bad things about RPL in my opinions are the size of the switch in the back. It's hard to see what number it is set on unless you angle it perfectly under light. Also, it would look a lot nicer if the huge red on/off button was different and didn't stick out so much.
I want to thank Jack for such amazing unit (and for all those free optics again !!!). I was skeptical about even higher power units having good beam quality, but I can tell you guys I’ve never had or seen such great performing hand held laser.
And now few pics.
(All beam shots are done without any smoke and main ceiling light ON.)
