Review of the Rayfoss RF532 600mW-02

[ped]

Just a quick review of the 600mW greenie i obtained from Rob (Phoenix7)

Well what a laser! .

Equipment used :-

Usb Kenometer built by myself. (Parts supplied by Kenom obv)

Tornado K-Type Digital thermometer

Philips Laptop with Luminosity

Sanyo 18650 2400mAh

Photos

Size comparison with a Jarob 18650 445nm build

My meter

Close up of the head

The laser under test

IR filter retrofitted

Temp reading while under test...never got over 26c !

Dot at 19ft (please forgive my horrible photography) Dot was about 15mm

And finally the data graphs


Without IR fiter :-

With IR filter :-

And thats about it.

So all in all this is a beast of a laser

Pros :-
► relatevly stable
► very effective heatsink
► insane power
► Good IR filtered performance


Cons
► Poor divergance
► EATS batteries (to be expected!)
► Very bright blue LED

So all in all a very good laser, (thanks Rob) , beamshots & comparisons coming when it gets darker.

Thanks for reading.

The divergence may be a consequence of higher-order multimode operation. It looks like the beam is vaguely square.

Great laser and review though - good to see Luminosity is working well for you.

Thanks,
Could you explain that a bit more?

Gaussian profiles of various TEM modes.
Most common and most desireable is TEM00.

Mode-hopping is when laser changes modes.


Which one of these do represent your laser dot ?

 

[ped]

Hold on one moment, i'll get a picture.


*EDIT*

Pictures, again please excuse my photography. Taken at 19ft

More than 400mW of 532nm must be awesome!! May I ask you how much did you pay for it... $500.. $600..?

 

[ped]

I did a deal, i swapped it for an iphone 3gs and $100 , the iphone cost me nothing , so together with the customs charge its cost me around $250

 

[Trevor]

Hm... try expanding the beam with a lens onto a wall, then taking a picture at a really fast shutterspeed - try 1/2000.

From what you've taken, it looks like TEM12 is fairly prevalent...

I was thinking more like TEM00 just with dirty lens a bit. It does appear round overall.

Taken with fast shutter at 6ft, beam expanded..

Not bad

Ive just found the dark filter for the camera, i'll get more shots.

Hey ped,

Regarding these images:

That's definitely some high-order mode.

If it would be possible, could you get us a 60 second run video?

Tape a piece of flat, white paper to a wall, and shine the laser through an expanding lens (a clean glass magnifying glass works fine). The spot should be around 1cm wide on the paper.

Point the camera through the goggles, and record a 60 second video of the laser as soon as you turn the laser on.

 

[ped]

Not a problem, i'll do it when i get home. (in work ATM)


EDIT.

.

As requested, though i kept the video running for 2 mins because it kept mode hopping.

I name this laser "Skippy"

Video now added.


( and a cheeky lil :bumpit: while im about it )

You forgot the "-" in your videocode
