My projector

[FourDee]

I just realised that I have not yet shown you guys my projector.
It's been ready for 6 months now.

I did the best I could with the housing (and to be honest I hate the shiny finish, I'll probably change that to matte sometime soon)

Specs :

• CNI Green 200mW measured at 300mW
• CNI Blue 100mW measured at 120mW
• Homemade dual red estimated to have approx 400mW
• DT40pro's
• FB3 for control

So here it is (be gentle on me ) :

Front : Hoya filter on the output and grille for the electronics compartiment



Back : Powercon for power (duh!), ethercon for signal and a jack for shutter



Bottom : An alu heatsink is incorporated for the galvo drivers



Inside : coulour mixing



And some beam shots :

fourdee-

looks GREAT! excellent job. i like the layout with the bounce mirror for the blue. MUCH easier to align. approx how much are you losing on the bounc there?1mW-2mW??

thanks for sharing!

No idea tbh
Lasers were measured with someone else's power meter (don't have one myself)
I used the laser-wave mirrors, they are spec'd at >99% reflective

Oohh... Ahh....

And some beam shots :

Could you tell me more about your filter? Is it a standard camera lens filter, or something more exotic? Do you get a lot of losses or back reflections from it?

Ta,

That's my fav pic from that series too

As for the filter, it's a simple UV filter for cameras (72mm)
I do get some reflection back into the case, but it'm glad to sacrifice some output in return for clean optics

Btw : I did some experimenting a few days ago

Beautiful colours.
I'm reading this at work and getting laser withdrawal symptoms !


Nice work.

[FourDee]

Nice to hear

The colours acutally get worse once everything gets warmed up, bacuase then the green gets the upper hand ... but now I'm nitpicking

...The colours acutally get worse once everything gets warmed up, bacuase then the green gets the upper hand ...

Oooohhh... that sounds very dodgy.
And terminal.

Tell you what, I'll give you 50 Euro's to take it off your hands before it all explodes, taking out half your house with it.
But only cus I'm such a caring kinda guy.

Go On !
You know it makes sense !!
