waterproof and a cool design to
*<1.5mrad at beam aperture! great...if its true
Working Current*I<650mA ¿

btw check that host with blu ray in it 300mw driven @ 550ma!?¿ doesnt seem right
*edit runs on cr2 and shows a 18650 now im lost

There is a new collection of this host @Rayfoss
They also offer a 300mW 405nm for 160 bucks

I would not bet on the beam shape .. also I can't see if it is focusable.

im bout 99,99% sure these cant focus its a fixed head

i wish they sell the hosts alone

Ii will ask Faona if she would sell the hosts alone.

Usually when they are focusable Rayfoss states it in the description. This one doesn't appear to be, but I will email Faona and ask about it.

Heads Up...

working Current 650mA...

It takes ~1000mA to get ~1000mW of 445nm output
at the Diode..

Using only one 3.7V battery points to a boost driver..
With a boost driver...the current straight out of the batteries
will be much higher than the LD current..

If the LD current is 650mA then the output will be nowhere
near 1000mW...

I wonder what other data on the link is as badly Skewed...:undecided:

that was what i was thinking, also look at the blu ray version 550ma for 300mw:wtf:

 

[DrSid]

550ma for 300mW sounds about right to me ..

 

[mikeeey]

550ma for 300mW sounds about right to me ..

actually... no, that can't be right, because I have a 215mW blu ray running at 195mA (with the 405-g-1 lens).

550mA at 300mW sounds more like a red laser with a cheap lens.

 

[JLSE]

that was what i was thinking, also look at the blu ray version 550ma for 300mw:wtf:

Id imagine that includes the total draw from the battery to a boost driver
to up the voltage and the current to the LD.

I am absolutely sure that it looks like a "circle dot" at 4 feet

However, at 40 feet . . . . . . . not so much :tsk:

Peace,

Touche .. that is what I based this assumption on .. didn't expect blue would be so different. It's because the working voltage is different right ?

We all know the Casio diode puts out a bar shaped beam. Kinda doubt a dot circle.

Water proof is cool. Good price.

30 second duty cycle? Heat sink issues?

I assume it is not focusable.

Yeah, even if they drove it to get to 900-1000mW, they'd have to be using a mask aperture to get a circular beam. They'd probably have to over-drive it at (what?) 1800mW or more (60% loss for a circular beam?) to actually produce a circular beam at 1000mW. And that would have huge heat problems because of the mask.

I'm guessing they either have to be wrong about the mA consumption, the round beam, or it's really about 400mW like the round beam Dragonlasers 445.
