Review: Rayfoss RF532-50mW-FLX with video (match-lighting!)

Hey guys,

my Rayfoss 50mW FLX laser finally arrived after one month due to vulcano ash
You guys helped me a lot finding the most suitable laser for me, so I decided to show you my gratefulness in a review.

First, some Specs:
Wavelengh 532nm
Power Output 50mW
Dot Shape Circle Dot
Beam Style CW
Divergence <1.7mrad at beam aperture
Circuit ACC
Working Voltage DC=3V
Working Current I<350mA
Duty Circle 180 seconds
Working Temperature +20dgC-30dgC
Storage Temperature -10dgC-40dgC
Power Supply 1pcs 18650 Li-battery
Size 30mmx165mm
Package Retail Box+battery

They also included a charger in the package. Faona also said, she would send me a european adapter and another battery for it, but it seems that they forgot it.
I just emailed Rayfoss, lets see what they say.
EDIT: Got a reply: They will send it to me.

Oh, theres one thing that is confusing me: Faona said the laser duty circle would be 60 seconds, but the specs show 180 seconds.
I think I'm going to stay with the 60 seconds, just to make sure I don't mess up the laser.

Price:
It cost me 45$ + 5$ shipping = ~35€
Very low price for such a laser!

Look & Feel:
The laser feels solid and a bit heavy. It has the torch-flashlight style.
Quality is not perfect, but good. It had some small scratches, but I don't really care about these, because the laser was very cheap.
The power button and focusing ring is solidly fitted, only the aperture is a little loose.
It also has a blue LED, that shows, that the laser is on.



Key lock, focus and aperture:
You can close the lasers' aperture and lock it with a key to avoid accidental usage.



Power supply:
The laser uses only unprotected/small (?) 18650 batteries with 3.7V.
The batteries included were No-Name batteries.
My protected 18650 TrustFires from DX do not fit, they are too thick!

IR filter:
The laser does not have a IR filter, like most of the cheap chinese lasers.

Output:
Since I don't have a laser power meter, I can not measure it's real output. Sorry guys!
But I can compare it to my 100mW True DX pen laser. In comparison, I would say both lasers have pretty the same output, but the Rayfoss' divergence is better.
DX lasers are usually underspec , so I think its about 60-80mW.
The output is very stable! My DX lasers' output changes every time I move it around in my hand. Not with this Rayfoss laser, very stable all the time!
It takes about 5+ seconds to get the full output power.



Burning:
When focused, it CAN BURN A MATCH! I really did not expect that!
I will show this in the YouTube video below

If you guys have any questions, ask them!
I hope I could help you by doing this review

The mrad is 1.7 but is focusabel you can focus at 0,5??
Thanks

nice review :gj:

stuart

I'm going to have a look at the mrad.

Btw: Video is up.

Danke schön !

I would have bought this laser, but I wanted a cheaper one.
Well, it has very good quality !
Nice video too.

No, listed divergence is the best it can get. If the could get 5mrad why wouldn't they put it on the specs.

I added a DX True 100mW comparison

can i have it plz? :yh:

I think he made a mistake in the divergence calculation (or measured "reverse" div. while focusing). :undecided:

No, I made a mistake I meant to put .5mrad, but other than that what I said was right. He thought that companies suck at focusing, and that since it's a focusable laser you can focus it better. Which is not true. 1.7mrad is about the best divergence you can get with that lens.
