Laserworld

LOL!

Yeah I even found a dead BEE in a little space next to the exit window...

Now I know better why I'm bothering to make my projectors dust proof, with a sealed optical part

Heya All

I don't want to bring anyone down, but i think it might be posible, even thou i'm probably the only person here to suspect this, that your not the first person to take the top of this laser and have a fiddle. The mirror and dicro looks like someone has done a Homer Simpson repair, where there any bent over nails used to repair it in there?

As for the scanning speeds, yeah i think it's common knowledge they don't do 50k.
But i've found they have a huge angle and there about a sixth the cost of CT's.

So i know this might seem hard to belive but "you get what you pay for".

Trust me when i say this, as a reseller of chinese assembled lasers.

Also you'll might find that laserworld mirrors and filters have to be maintained just like everone elses that uses unfilter air to cool them.

And yes, i'm like you, the next projector i assemble i intend to filter the air to it and keep the optics chain in a separate space.

Cheers

thank you for your $.02, Kiwi Troll. We all know you're in bed with Laserworld and I think we've seen enough from Laserworld over time to know who we're dealing with: criminals.

You going to sing me another song, Kiwi? Why don't you make it a love song about Laserworld?

I'm going to chip in here been as I also have the RS series in my possession and have had the top off.

The case seems fine to me although others have said the base is too thin for their liking. I've had no problems with alignment though.

The build quality on the one I have was excellent and very clean inside although I concur in that the dichros are typical, they really are pieces of crap - mirrors stuck roughly on plastic mounts with hot glue. The scanners on mine are fine and certainly don't have mirrors fixed on like that.

The one I hold is over power - obviously lucky (!) from others experiences, although the red beam spec is typically crap - a huge beam thats so wide it even misses the Coherent laser check from a few cm. Still exceeds spec though. Green beam is nice and tight.

All the lasers in the one I have, have the powers stickered out by Laserworld.

Fans are noisy but again no biggy. You don't here them over music and can easily swap them out if so inclined.

If you want a closer look inside the one I have, there's a video of myself and Jem doing a power check on it here. You don't see a lot inside but you can see its very nicely built. The video is HD so not detail is hidden:

The one I have hasn't been used apart from the check and the demo video as I have RGB desires so don't intend to keep it for myself. It will be sold eventually even though its a good one.

There's also the demo video on there as well. In a well smoked room it does produce a very nice beam show.

JOKE ALERT !!

....."you get what you pay for"......

Is 'e 'avin a larf or what !?!

Did you took the measurements while scanning patterns? I can see some scanned output from the projector, maybe I'm wrong... But If yes the laser output should not be at full power since blanked!
Another point on the green one is that I'm not sure at all it has an IR filter, so should influence the measure on the Lasercheck too.

BTW, if I want to repair the defective green, I think nobody would advice me to contact Laserworld to buy a spare laser from them? I think it would be better to find another laser from another source...

I want to kown more about the laserworld,where need I learn?

You have right here 22 pages of informations about them, I wish you a good reading

Its TTL as its only RGY.

As for IR, quite possibly is some IR although the lasercheck is supposed to be frequency dependant ie it measures 1 frequency at a time. How good the rejection is from other frequencies I don't know.

What I was trying to tell is since the Lasercheck measures the average power only (and not peak power), if you measure a pulsed output (it is the case when the projector scans a pattern), you will not measure the max continuous power of the laser, but the average of the pulsed output depending on the blanked lines of the pattern. It can be close if there's a high duty cycle, but you won't have the full power reading.

You have to put 5V continuously on the ILDA input corresponding pins to measure the real CW power of the lasers.

Btw, the lasers are analog (at least in mine), but the electronic control board aren't.

And the Lasercheck readings are very influenced by other wavelenghts (for example residual IR from a DPSS laser), so you have to put an IR filter before it to ensure a correct reading, or measure after a reflect red/pass green dichro.
