Re: New Nichia 9mm 1W 520nm diode
Very exciting, can't wait to try one!

Re: New Nichia 9mm 1W 520nm diode
that SS is from a different diode, supposedly.

Indeed but really the scanner mirrors waist quite a bit it.
PT-30 Scanners have pretty big mirrors which would be perfect for a very small RGB build based on 1W blue, 1W green and 2 x PBS P73.
Might be a nice idea to make a challenge now, who can make the smallest 3W RGB projector
that runs at 30k scan rate.

Re: New Nichia 9mm 1W 520nm diode
Are those facet dimensions?
If they are, the ratio from reds (7/35) ~= the ratio from greens (11/46).
I would expect divergence very similar to that of the red diode.

Re: New Nichia 9mm 1W 520nm diode
Lol its at a $ per mw. Just as expensive as DPSS at the moment. I would be so happy if the price of these dropped below 200 EVENTUALLY. I can wait a year or two.

Re: New Nichia 9mm 1W 520nm diode
Thats divergence in degrees (º). The green diode is 11º parallel divergence and 46º perpendicular divergence.

$ per mW if not over overpowered but yep they are not so cheap yet. Maybe if a Video projector starts to use them, the price will fall to < 50 dollars. I suspect given the design and specifications is very similar to the 445 1W, I suspect they are destined for some video projector.

@andyf97
Not really. That only means that the same company (nichia) manufactures both diodes...
@ixfd64
Sure they are. Look the big divergence... :beer:

I don't think anybody's gonna try that too soon, at least when the diodes are at their current price
we'll find out eventually
I wonder who the rich guy was on ebay that bought 3 at $950 each :lol:

Re: New Nichia 9mm 1W 520nm diode
No need to wait for one or two years. I bet these will beat DPSS $/W in 6 months. Maybe not the low power greens (<100mW), which are really cheap on ebay, but I'm almost certain about the high power ones.
In two years I guess DPSS 532nm will be used only in applications that need WL stability or a better beam profile.
As for the divergence, IF the ratio of the fast axis/slow axis raw divergence translates directly into beam specs - which I'm not completely sure - these are at 4.2, between the 445nm 9mm (at 3.1) and the 500mW 638nm (at 4.7). Pretty bad indeed. I'm hoping these numbers don't actually mean anything.

Re: New Nichia 9mm 1W 520nm diode
Mind you guys this is only the first version of the diode. It'll get revised and fix up the beam specs slightly in all likeliness.

Re: New Nichia 9mm 1W 520nm diode
Hope they do, or that Osram comes up with a better one XD
Not sure if these are fake or made with this diode:
520nm green laser pointers really 1000mw laser tourch laser flashlight-in Laser Pens from Consumer Electronics on Aliexpress.com
1000mw green Laser pointers The first 515nm 520nm pure Green Laser Flashlight in the world 515nm 520nm-in Laser Pens from Consumer Electronics on Aliexpress.com

Well DPSS 532 is around $650-700/W in lab lasers. Hand held they are already about the same per W, although the DPSS has better divergence. It would be a miracle if we found these Nichia diodes in a cheaper projector like the A140s

Re: New Nichia 9mm 1W 520nm diode
You probably don't have to wait that long. The 445nm diode was $500 when they first appeared on ebay but dropped an order of magnitude to $50 after just a few months.
