Good god!

How the hell they get away with it I will never know.

That's Kvant money. I think that's in the ball park for a 1.4 W Spectrum which considering the Laserworld's making a reported 1.5W makes it look very expensive given Kvant quality and Cambridge scanners.

Just been looking at this:

630mW RGB with 100mW of 532, 70mW of 473 and 300mW of 650 How the heck does that make 630mW

[White-Light]

Just out of interest, I put the figures through Chroma:



Looks like its light on red.

You could certainly get a good white though by scaling back green and blue output though as its dead centre (red balance apart).

Hahaha thats where Carl bought it from - just down the road from me in Warrington

PS is the image there of the blue and yellow beams supposed to show a cool effect or how badly out of alignment it is??

Well I have never used Chroma because its all subjective and the white that projector made was outstanding without backing anything off. Theory is all well and good in..erm..theory () but real life is what matters

You could probably get the 2.5W Kvant for that money. It is listed as 15K Euros.

Very nice write up Rob! Too bad it turns out mostly negative for Laserworld.

FYI, I only get 250mW of 640 from the out put window of my Kvant and the white if beautiful.

Rob-

I need to correct a few errors you have of your LASERWORLD LASERS REVIEW.

appart from the scanners being out of tune and the alignment of the lasers being poor, there were some strange artefacts in the output. He had reported to me on the phone that the green beam wasnt hitting the scanner mirrors square on and that there were diffuse green artefacts to the left and right of the scanned image.

Rob-
The lasers werent out of alignment. The scanners werent out of tune. There were no strange artifacts on the output. What you were experiencing was the "LaserWorld differential Laser output phenomenon." See, this happens ONLY to LaserWorld Lasers and can be explained PERFECTLY by any extremely talented, smart and Laser saavy LaserWorld Lasers employee. The lasers they make and sell operate beyond the known realms of our mere mortal cognitive reasonings. They bend our rules of physics and therefore us dumb PL laser hobbyists will NEVER understand the high tech lasers and technology that LaserWorld Lasers sells.

Next we retuned the scanners at 30k - there is no way without serious work that they will go near 50k and for them to be sold with this rating is insane.

You are incorrect. If LaserWorld Lasers says they are 50K, they are 50K. Your tuning methods for tuning scanners is different in England than at the factory where LaserWorld Lasers are made. 50K is COMPLETELY different at the LaserWorld factory than it is in the "real World!" You must not have been using the PROPER left handed screw drivers when attempting to tune the scanners to 50K. My suggestion would be to use a Left handed screwdriver. You also MUST, i repeat, MUST tune the left scanner first. THEN the right! if you do the right one first it will NEVER work. if you follow my advice i GUARANTEE you will tune these to probably 75K!!!

Before we started a single white beam with all lasers on was measured at 1200mW off the scanners and after we had finished 1500mW, so we improved it by about 25%! but still it was nowhere near the 1800mW let alone the 2100mW theoretical max power.

was the measurement made at room temperature? was the humidity below 40%? was particualte in the air less than 200 PPM? was the rain falling that day at a 8 degree angle? were all of the electrical appliances in a 37 mile radius swtiched to the "OFF" position? was your seat and tray table switched to their full upright positions? did you shoot the laser beam into your laser meter from right to left? beams CAN NOT enter laser meters and get a proper reading if they enter from the left to right!! these are ALL factors which LaserWorld Lasers needs to have in order to get proper readings of their laser outputs!

Also-

if you measured 1.5W, that is EXACTLY what Laserworld Lasers advertises. Their Laser powers are different. PLEASE remember that. See, Germany (or where ever these things are made) is about 300 miles above all the other countries in the world on the globe. so, light radiation in Germany tends to be 300mW (or lumens, or whatever you would like to use here) brighter due to them being closer to the sun. So, please factor that in. if you do, you will see that the advertised output of 1.8W was indeed, 1.8 Watts. your 1.5 Watt reading, plus the addition of the 300mW LaserWorld Lasers light output constant!

The 10mm thick ally baseplate is made from what could never be described as Aerospace quality material its soft and unpleasant to work with (as I found out when I drilled a hole in it)

If you had the proper tools like the left handed screwdriver i told you about and the magic laser aerospace flux capacitor and the flimflam wogglebots, you would realize that this is indeed EXTREMELY high-end and technologically advanced aerospace aluminum. Please do not do a review of a product if you are not using the proper tools!

We found we could get the alignment to drift out significantly by putting the lid in place and screwing in the 2 M4 screws adjecent to the baseplate using very light screwdriver pressure. We also noticed how much the lid buckles about when putting screws in as its clearly made for a different case - its just not a good fit.
The baseplate had a bend in it in the centre at the front right where the dicros were mounted

the base plate doesnt flex. your house happens to be in a part of England where the gravitational fileds are different and the effects of the "pull" of gravity happen to not work correctly in your laser test area. Please be sure to note your errors. The buckling of the lid is due to the fact that the air pressure is less where you are than the rest of the world. it was causing the metal to expand.

Laserworld gets a big thumbs down form me

you should have performed the tests PROPERLY and you may have gotten MUCH better and LaserWorld Lasers approved results. ESPECIALLY if you performed the tests 2.4 days after the last full moon.

PS I forgot to mention the fans - this projector has lots of fans which are very noisy and not one has a filter on it including the one that blows directly into the scanner/dichro area!

the fans are used to blow the laser light back into the lasing cavity. this causes the laser beams to re-combine with each other and make more power. the more fans the better. how could you not know this?? The noise you hear is the hum of the extra special, re-combined laser light. it is also known as it is known in the engineering community as:
"FREELASER"
Fan Recombined Electrically Excited-LASER

Rob, your review was thorough. but please remember all of the above next time you test and review a LaserWorld Lasers Laser system. they are COMPLETELY different than EVERY OTHER laser system in the world. They dont follow the same theories of light and optics as the rest of us are used to!!

thanks for your efforts though.

LOL

Excellent Sir Marc

Did they PM all that to you

[stanwax]

Sorry Marc
I am just a mere none German mortal with no prior working experiences under the employ of LaserWorld so you are quite right, I clearly failed to factor this in making all my measurments and observations null and void.
Im sorry if I have missled or missrepresented to the public and other non-professional laser hobbyists.
Based on this the output power was actually double what I measured and the scanners as you say were good for 75k.
In future I will not try to enter an exclusive professional world that I have no place in.
I consider myself told
Maybe I will stick to building custom projectors in the vain hope that one day I can aspire to the greatness of Laserworld.

NOT!
