NDS4216E - 200mw 488nm diodes

[Stoney3K]

Yes, but you'd need more of it for a good white compared with 445nm. That means unless you feel like knife edging 12, you'll have to bring the power of your other colors way down.

Or you could just combine it with 445nm, along with 532, (possibly) 515, 638 and 650nm and get one hell of a colour gamut.

exactly, having only 488 would severely limit your deeper colors on the blue side of things... but mixing multiple blues really expands your color gamut

488 is a great color. I'd like one in a satellite projector. Hope they come down in price.

In theory..
But in practice you'll end up with mixing singlemode, multimode and dpss sources, which you'll all have to match in diameter and divergence and spatially to actually look good.

Mixed gas doesn't only have superior color performance because of the many lines in the color locus, all beams are collinear by definition.

..but it won't give you a hernia carring it around
Also, mixed-gas ar/kr has only two red lines, right? 647.1 nm, 676.4 nm.

its really not that noticeable... I have 445 and 473 and I have significantly more colors than with just 473, and additional colors than with just 445

mixed gas is great and all but theres a reason most people don't use it anymore and are dumping them for pennies on the dollar

Mixing a bit of 532 along with your 445nm makes the colour come pretty close to 488, so that's a good alternative if you're on a budget.

[shrad]

has anyone remarked the ESD protection device built in?

is this an evolution of lasorb technology or have them developed their own solution?

[andyf97]

Most newer diodes seams to be having forms of protection, Lasorbs are not really needed anymore unless using opnext diodes or similar.

I can see it now " 10 watts of 488 "
