1W 520nm Nichia Laser Diode TEST

[csg]

As seen on the Dutch LEM RGB with 1w 520nm,amazing modulation and colours! looks perfect to me ;-)

thanks for your photos - i know there has been discussion regarding the camera not doing justice to the yellows, but the 4th shot seems to display the issue well - its more of a straw colour, not a saturated yellow. the green shot also looks quite dull compared with the zip that 532nm has.

I was always dreaming about a 570-80nm ish DI Yellow Orange Diode RRGGBBVYO DI diode in a small PJ would be a dream hehehe

I thought we would never see green diodes so yellow might happen. There has to be reason beyond our little hobby for someone to do it. Confocal microscopes might be that.

Hey Guys -

I'm gonna respectfully-propose we all move these 'color-mixing discussions', HERE: http://www.photonlexicon.com/forums/...856#post282856 ..out of respect for Alex's thread / desire for useful-data cleanliness, here, vs having to wade-thru 16 pages of irrelevant-arguments over 'who's software lens first scanned the fastest pair of mechanically-blanked ILDA-formats, and kept it under 100x MPE for the audience'!

..Just a suggestion in the suggestion-boxx..

re:

Is there some interest in 520nm coated mirror prisms?

Absolutely! I'd like pricing for 20x pieces, and 60x pieces, to-start.. Not sure if it will be 'different' if-less than 100x, but.. that's where we'd wanna start.. Oh, and, IF 'samples' are available, yes, we'd want a couple-two-three

..I'd say, we'd probably want 5mm's, like for the 445s.. Would you recommend otherwise, for these 1W-ers? Please advise..

Danke, Alex...

You may be able to partly compensate for the 12-14 nm blue shift and that effect on yellow saturation, but it will not be possible to fully compensate. If it were we would be able to add cyan in enough quantity and use this to pull the magenta line between red and blue to yellow as well. This is not going to happen.

Because most current DPSS lasers and I assume these 520nm diodes are polarized, why not PBS combine a single diode to existing. projectors? This would up the power 1W, increase the color saturation of the cyans and because the existing color correction boards allow for 4 channels would permit perfecting the modulation tails? This would also require minimal changes in the existing architecture.

Exactly my thought !

Do the same with 2 shades of blues-cyan (450nm and 480nm or better = 450nm and 500nm) and then you will have a nearly perfect color coverage.


Something I realised a few time ago ----now confirmed by the color schematics--- justify the "no-difference " perceived by the eye between red 635-642nm area and the deeper red @t 658nm : minimal difference in therm of color coverage (you have nearly the same saturated colors) but the real brightness change a lot.

Thank you for your kind proposal regarding the color balance discussion.

I sent a request for 520nm prisms. Will open a GB thread as soon as I got the prices.

Just fired one up these are awesome. I think the beam is actually tighter than the M140 or 9mm 445's. Bright as hell as it is the middle of the day here and the beam is very visible inside.

I will do some power tests tonight.





Here it is @ 25 feet.

that's awesome!
