wanting to build my own rgb and i don't now anything

[zpeakabonk]

hello

i want to build my own rgb because there are to much crappy rgb's

for sale and expensive too

so i would ask what do i need what should i look at what not to do etc

i would like to buy cni lasers i already quoted them

my idea is 800mw 635nm red
600mw 473nm blue
600mw 532nm green

and 40 or 60kpps galvo's but i don't know which one i should take cambridge or scanpro's etc


also would i need a very big and badass case ora normal case

and all the other stuff i would need

please give me all the info even if my setup idea sucks

thanks a lot i will open a thread if i start building this baby


greetings from france michael

Hey Michael,

Sounds like you may have a fair pot of cash to spend looking at your specs there.

You say you want CNI lasers, you might also want to look at Laserwave, there are plenty of distributors on this forum. They are also *very* good quality lasers...

Another tip, if you can stretch that far is to go for 640nm red. 635 is very bright, but you generally end up with a fat and divergent beam. 640nm is also very bright, it has close to the beam quality of DPSS and can produce much deeper reds than 635nm.

I have a similar setup, with 600mw of 640, 800mw of 532, 300mw of 473 and 500mw of 445... This setup gives a perfect white balance, even at full power, an amazing colour palette and a very small, tight perfectly converged beam... The 445nm is a deep blue and gives amazing magenta's, violet's and of course blue's.

I have ScanPro 40's which are amazing scanners, although Cambridge are better if you want to do complex graphics, but this is taken into account with the much higher price...

hi i have seen your baby and it is sick
very nice laser i have asked cni for 445nm but they don't have big power only 20mw

could you tell me what you paid for it?(445nm)

and what are the other things i need?

and where did you get this housing

i will check the laserwave's

thanks michael

The 445nm came from Kvant and the price was somehwere around €2700. But worth every penny. For Kvant lasers, speak to Pelosh on this forum. He is the UK distributor for Kvant.

You would also need a first surface mirror on a kinematic mount, a pass green reflect red dichroic optic in a kinematic mount, and a reflect blue dichroic optic in a kinematic mount. All available from Laserwave distributors and Edmund optics. If you want to mix 473 and 445 as I did, you will need either a narrowband dichroic optic at those wavelengths, from Semrock I believe. Or you can try the cheaper option of a Polarised Beam Splitter cube coated for 473nm. It worked for me, but I might have just got lucky.

I made the case myself, but if you go to your local sheet metalwork company they might be able to do it for you.

You must ensure that the optics and electronics are separated. Either by making a two level enclosure with optics on top and electronics on the bottom level. Or make it on a single level and seal the optics in a perspex or similar enclosure within. The electronics need plenty of forced airflow to keep them cool. Fans introduce dust and you don't want dust on your optics. The lasers at that power level could burn the dust particles onto the surface of the optics and permanently damage them.

ok thanks i will think of it to make combined blue and red or not

would be easier not to but it is more fun to do it

i think that scanpro's should be good enough i don't do complex drawings for the moment

the prices i got from cni are ok but they talk about stability<10% is this ok or not

about the price for 640nm is it in the same range as 635nm?

thanks michael

[zpeakabonk]

this is what i recieved from cni does anyone knows these modules are they good or crap?

Dear Michael,

Thank you for your e-mail .

Please find the price for the laser as below:
635nm 600mw
MRL-III-FS-635-600mW stability<10% PSU-OEM
USD1000.00/pc
655nm 1000mw
MRL-III-655-1000mw stability<10% PSU-OEM
USD500.00/pc

532 nm 800mw
MGL-H-532-800mW stability<10% PSU-OEM
USD1000.00/pc

473nm 300mw
MBL-H-473-300mW stability<10% PSU-OEM
USD1600.00/pc

thanks for info's

Holy Jesus,

US$1600 for 300mW of CNI 473, thats half what i payed for mine.

US$1000 for 800mW of CNI 532, thats per mW/$ a quarter i payed.

"It's a deal, it's a steal, it's the Sale of the f**king Century!"


Even so i think you'd have to be off your head to build a projector, i ca'nt imagen what would motivate someone to do that. Considering the cash your going to spend on the diodes, this thing is'nt a hobbyests machine.

If i was to build it, it would cost more then Kvant would charge and that would be without me charging labour. They get better deals on components as they bulk buy.

I mean your talking some serious power values. I had a 300mW 532nm with a 1 khz switch and if it hit you in the eye it's like getting a flash from a MIG welder. 800 mW of green, man i wonder if your get a tan off standing in front of it.

At what point do toys become weapons?

CNI lasers are very good, but I would definitely speak to a Laserwave rep before making your purchase...

about the price for 640nm is it in the same range as 635nm?

Again, speak to Pelosh from Kvant and the Laserwave reps for pricing. I bought my 640 when they were new on the market, so prices will have probably changed by now.

i think that scanpro's should be good enough i don't do complex drawings for the moment

Scanpro's are very capable scanners, I am very happy with mine...

Cheers

[zpeakabonk]

ok i will

i have already asked for the case and they are very nice price is ok for me

i will check all the price's and after decide what modules i would take

for the galvo's i see that at scanpro there is an offer for the 50kpps so i will buy a set of those


thanks michael

Hi Michael,

Shoot me a PM, and I will work out some special PL pricing for you
