not sure if they are button top or flat tops

any updates on RGB?

Hello, Im trying to purchase a sanwu guardian & want to know, does the multi operations mode make the laser completely useless if you don't know the sequence or does it still turn on at less power?
Also 520nm vs 525nm , any suggestion on pros/cons?
already have goggles, ty!

I can't post links yet I don't think, but if you search for

Sanwu Silver 4W 470nm Blue Laser Pointer Review​

On youtube, at around 8:30 in that video he shows that the sanwu multi "off" mode is a very weak on (he guesses 1mw). I doubt it would be different on the guardian, but you might want to email their support and ask.

As far as differences between 520 and 525, I know nothing about the diodes but their color will be extremely similar, with the 525 at equal power being just a hint more visible.

1.6W of 530nm greenie is up for pre-orders now!

Wow - what's the diode for the 530nm 1.6W? Bet it's incredible.....

Divergence?

It's NDG7D75t which has been discussed in here for the past few months.

It's similiar to NUGM03/M06, we are trying to correct the beam using optic fibre.

 

[CurtisOliver]

That's an interesting approach. Are you planning to use that for your handhelds?

Yes we may implement this to our handheld lasers as paid addon in the future.

 

[CurtisOliver]

That's a cool feature. Don't know of any handhelds that use optical fibres to correct the beam.

Thanks Podo, I've not been keeping an eye on the forum for a while but when an email popped in regarding your post and the 530nm 1.6watt Sanwus, my ears pricked up!!! I'll take a look back through the thread thanks and I might just order one from you at a later date. Going to have a look at the data sheet. Thanks

I wrote this in 2017. "One thing no company is offering are lasers with beam shaping optics. Personally I quite find lasers that produce a line rectangle and not a round spot or something close to that a very compelling reason not to purchase. I had my eye set on buying a 462-465nm laser until I found out the diode produces a line, not a spot. A beam correction optics feature could be offered as a laser ready made or as an optional add-on."

Same. Got a random email and was instantly checking Sanwu website. lol. Also curious how much a fiber optic would lower the output power? Like say you had a 2w 445nm. What would it be after shaping the beam?
