*update*
I measured the laser today again and now it got a little more stable once it's warmed up.
The chart goes to a peak and then power drops slowly, but I won't let
this baby get too hot.
Here's my new record peak:
I got today my newest laser:
finally a 473nm
it can be seen here:
Spartan Series 20mW Blue Handheld Laser :: Blue Handheld Laser ----- 473nm Laser ----- Spartan Series Lasers :: Handheld Lasers :: Dragon Lasers
Company, Shipping and Packing
First i asked on the website about the laser if they LPM it and if it's IR filtered.
Chat was offline and I received a mail the next day from Frank aswering all my questions.
I ordered the laser on 18 of July and I got it the 29 of July.
Compared to other Asien companies that's really fast but of course it was pretty expensive (35$).
They shipped with tracking so I could always watch where it is.
So package arived and everything was well bubble wrapped packed and the laser was in a anti-static bag.
To my surprise there was also a battery already inside the laser.
That's why it felt so heavy when I took it out
I also ordered some glasses with the same order. Everything arrived in good condition.
Laser / Host
The laser is a Spartan, made from CNI.
It's quite heavy in your hand and it was a little longer than I expected it but I guess the module takes up some space.
The laser has got a clicky butten at the end and it doesn't have any safety features.
So with the battery already inside it could test it shortly how it looks
I took the head off and you can see the IR-Filter glued on.
It seems to be done a little bit sloppy as also does the lens which is glued on not being in the middle of the aperture.
I didn't open the laser any further than that.
Beam / color
The color itself is really beautiful, a pure light sky blue it's for me
and when I look at it next to a 445nm laser it seems a little turqish.
Some beam shots inside in the dark Without anything added:
I tried to test beam divergence but that was a bit difficult for me.
It goes like...
Dot at aperture seems to fit the specs from the website so it's 1.8mm (pic thru glasses)
at 1meter it was about 3mm big
and I measured also at 10m and that was difficult to say but I think it's about 9mm big.
With glasses I couldn't see the dot much and w/o the dot overshined so it's not exactly at all.
But given this I think divergence is lower than 1mRad.
Also the dot is very round after warmup. It seems like perfect Tem00.
Before warmup it's a little oval and it also seems to "move" around until it becomes round.
Power
After what I heard from Dragonlasers around here I hoped to get a little overspec laser.
But in fact it has about double the power as advertised on the website and as Frank assured me it will be on-spec.
The power is unstable. Much more as I was used to with the 532nm's.
I think the 473nm likes it pretty hot. So when it's cold and not warmed up it will first only be in the teen numbers
then suddenly rise a bit when it gets warmer.
LPM-Test:
I only did 45 sec. tests. But sometimes with only short breaks between.
Room about 20 degrees warm. Laser cold.
room was quite cool so laser only a little warm.
and after that when the laser is warm it goes tipically like that:
here with the maximum peak:
The charts looked all so different but on all was...
1. laser needs warm up
2. after warm up, the peak comes quickly
3. power drops relatively fast
Summary
I'm completely happy with the laser and the whole buying experience. :yh:
The laser is nicely overspec (I'd say avarage is about 35 to 40 mW) has a very nice beam and dot but is a bit unstable.
And... I love this color
