I am trying to design a custom sled for creating a RGB (using a 5mW osram 450) & after examining & taking apart some old DVD & burner sleds I am wondering what the effects of combining the beams before they reach the collimation & focusing lenses? To me, it seems most sleds try to combine the...

yep, just what i would've guessed. a 450@80mw is 68% as bright as 532@5mw according to the calculator. my 1W is just slightly brighter beam then my 532@5mw even though the dot is much brighter (well, not exactly brighter, but scatters more light)

I don't think such a diode exists or is commercially available for a reasonable price. the one you want is the PL 450 by osram. (Opnext also makes a similar one). I was looking for the same thing. the lower blues are harder to see at a distance, even my 1W is hard to see from across the city...

pete- the diode your looking for is made by osram. there are 450nm poiners on ebay. either the diode or pointer will run about $60-80.

really? ok, thanks! I'll test both drivers and post my results. thanks again for the quick reply! any idea (guess) what kind of model# the ir diode might be? i want to look up the datasheet. also make a dummy load.

that spider III seems a little overpriced. it looks like a common host (just painted silver ). You might want to check ChinaVasion or dinodirect. they now carry 445@>1W. i think they were going for under or around $200. there's always eBay also. dinodirect has free shipping.

the keychain listed above uses a single AAA. i bought 3 of them from the same seller. two 532's & the 405 listed above. i know most people are probably more familiar with the O-like keychain host which uses a 10440. i like this one cause it's easy to buy batteries for when your away from home...

thanks for the help! I'll look into the boost drives. i need to power it off 1.5v though, as This is the keychain i plan on using ( I'm also making a 635 one): Check out this item I found on eBay: Blue/Violet Beam Laser Pointer with Keychain (Black) Link: Blue/Violet Beam Laser Pointer with...

What kind of driver would i use for the osram 450 if i wanted to make a keychain pointer? it would have to be powered by a single AAA battery (1.5v) because of the host i want to use.

also found this one -seems legit. uses the osram diode 5mW 445nm 450nm Blue Ray Laser Lazer Pointer Point New Link: 5mW 445nm 450nm Blue Ray Laser Lazer Pointer Point New | eBay (Sent from eBay Mobile for Android)

looks great! this is also $10 cheaper than the ones i saw + free shipping. (although, i really hate dealing with Hong Kong Post).

Crypes! ! that thorlabs 488 is over $3k! I'll wait another decade when they start putting them in everything (that's how long i waited for blue & white LEDs to get cheap). it's nice to know the technology exists. just goes to show, you can produce light emmiting semiconductors in just about any...

i don't have one, but i just heard about them &sounds perfect for rgb mixing. this is next on my list. thanks for the diode chart also. I'm gonna research these. i didn't think there was such a thing as a 532 or 473 diode without dpss. they're sure to be expensive if that's what they are...

awesome! thanks for the info. i knew there was another diode out there.

just read this. i'm researching how to build a rgb with a 445 instead of 405. the 445 would have to be low power in relation to 635 & 532. if the Nichia diodes can only operate around ½-1½W, perhaps there's another diode that uses lower specs. i assumed the Nichia was high powered because...
