Default Perceptual brightness mW power?

I recently bought a 405nm module from an ebay seller (geareb in Korea), quoted as 150mW, which I have no way of testing (yet). I'm making a home built laser show system and would love to have violet as one of the colours. Obviously 405nm doesn't appear as bright as other wavelengths - which I read and can now see first hand.

My question is, is it worth me spending the money and getting a higher power blu-ray module? Would something say, >300mW be noticeably brighter?

I'm planning to combat the difference in brightness by keeping the 405 as a single beam, split the 650nm up with diffraction grating and put my 532nm, 95mW through a spiro to spread it's power over a larger area.

the only one that would be any brighter if it is outputting 150mw would be the 12x.
also try the 405-g-1 lens to get more light out of the lens it blocks 29% less light that the standard lens.

Default Re: Perceptual brighness mW power?

Kinda depends upon what you want. If you plan on beamshows, 405 will never show well unless you use a lot of smoke.

If you are planning on graphics, there is a cheat you can do to give you a 'poormans' blue. If you project your 405 on a sheet of bleached white paper, the paper will flouresce a brighter blue color(I'm guessing somewhere between 440 - 473nm). Your green and red won't change color as they don't cause any flourescence.

Default Re: Perceptual brighness mW power?

Thanks guys. Yes it's beam shows I'm making and I have a home made smoke machine working well for that. I'm thinking I'll get one more 405 and run the two together or something. I love the colour, and the brightness is fine with lots of smoke and viewed from the right angle.

Solonar - that made me think, I wonder if certain smoke fluids would actually fluoresce, thereby giving a brighter beam in the air!? Of course you don't wanna breath any toxic shit, but a lot of pretty harmless chemicals light up when illuminated by 405nm... hmmm

as far as the florescent fog it will leave a coating on things and smell..
you could add a low powered green and combine the green and the 405nm to get a color around the 450nm-485nm

The 150mw version is a PHR-803t diode and should only be run at 80~90ma = 80~90mw

The 300mw one is a SF-AW210 diode and should be run at 180~190ma = 150~190mw

Ofcorse you can get more power and a tighter beam with a 405-G Lense for around 30% increase in power.

Allso dont pay extra money for the glass lense for 405nm from that seller he will only give you a cheep'er lens that is cotaded for 650nm
Hear is the propper glass lens / cheep'er alteritive to the 405-G, thogh not the saim increase in power. Only 5~10% cant remmeber.

Default Re: Perceptual brighness mW power?

If you are planning on beam shows, I would go straight for 473nm. There is just no comparison between violet and true blue in brightness. This is a good start:

80mW 473nm blue laser diode module w/ Double TEC [OL473BL-80] - $478.00 : Welcome to O-Like.com, Your source for laser products

The module above will be MUCH brighter than 300mW of violet.

You can also mix a tiny bit green in with the violet, that would both make it a little brighter and make the color a bit more blue.

Default Re: Perceptual brighness mW power?

thanks guys, exactly the kind of info I'm after. Learning heaps here.

Question - do you lose a lot of power and beam fidelity passing through beam combining optics?

You will always lose some. How much depends on the optics' quality.
