Hi Martin -

Kvick Kvestion...



Curious on these modules: Will they / do-they have 'external' convergence adjusts? (ie: like the Hungarian RGBs' do...

http://www.rgblasersystem.com/mambot...RGB4-front.jpg

.. that is a *really* critical feature, IMHO, especially for finicky graphics-werk, onsite... Does not appear-so, but perhaps I just do not see the ports / access-points
in the Kv5 RGB...

If these do not have any external-adjusts, my #1 suggested 'improvement' for future revs, would-be just-that... And - please - don't say 'but they don't move!' - EVERYTHING moves!! (...That's one-reason why we'll *never* buy an Arctos-style sys... - Not everyone does gigs just in nice, controlled / predictable-environments, like clubs, etc, ie: for many of our shows, we often have to deal with 'extremes' of environment / temp, etc, that can, and DO
influence convergence, no matter how 'tight' the little brick, is... So, imo, external-adjusts are... well, *priceless*...

Lemme know...
cheers...

Hi,

I haven't had that module in my hand yet, just saw it and to be honest I am not sure how is it sorted - but I am sure the developers thought it through.
There's days off work everywhere so I'll know more later on and let you know.

Cheers

well if its like the red modules i don't think they have any external adjustment at all do they??

they seem pretty well sealed off to me...

[pelosh]

don't get me wrong about my bitching, I know that the only way I am going to get a better red is a Kr or OPSL, but I really wish KVant would tell you, hey, that 1.2W laser is going to be 4 300mW beams, not 1 1.2W beam... and actually its not impossible to make a single beam high power 642 with enough PBS cubes and wave plates... which I kind of thought they might be doing since the damn module costs so much... but no, they are just knife-edging like everyone else

Good morning!

As I set before - the beams should join in about 1-2 meters distance and stay together. If they don't, there's something wrong and you should contact your dealer. 1.2W is actually quite low power module and every single one I saw had beautiful beam.

Still waiting for serial number and picture of four lines on the wall if you want me to investigate for you.

Thank you!

actually I was referring more to your reply to dslijon

while i think their RGB modules *should* have adjustments, I could also see why they may not want them to be user accessible... (most people that would want an all-in-one module probably should not be dicking around with alignments )

Hi Martin -

...but I am sure the developers thought it through.

Well, I will be very delighted to find-out that 'thinking-through' actually resulted in some adjustment-ports...

...I could also see why they may not want them to be user accessible...

Yeah, but denying the owner *any* access, is missing the whole point - ie: with the RGB-design:

(...and yes, I know, this is the *projector* version, but the sealed RGB-module is what's inside; the projector simply has sealed-extenders,
fused to the sealed-internal adj-ports...)

...sealed external-adjusts (like the MM-1s with recessed allen-sockets, vs thumbscrews) allow for converge-spanking, w/O access to the opticals, thus keeping all that messy-dust and class IV danger-danger out of the equation... 'Best of both worlds', imo... I don't seem to see anything like that in the Kv 5, but, keen to find out...

(most people that would want an all-in-one module probably should not be dicking around with alignments

Ah, now I see what you were saying, but why should I be 'punished' cause of the few doldrums that might crank such-adjs all the way to the south pole? If they're *that* much of a maroon, they probably shouldn't even own a class IV system... I mean, think of the benefits of an 'all in one' for something like an ML-10 - no-need to have a typical 'nekkid' R+G+B set-up, for such a rig, ya know?

And, too, even for an XY-graphics box, if you had like, umpteen of them, out on a 'Hugo Bunk-style' gig, if a module went south, you could be 'back up and running' much quicker, simply swapping-out the entire RGB-block, vs dicking-with an indie R or G or B-swap / realign, etc...

...But I certainly would not want to have to swap-out a 5W module, because the alignment somehow got off (...and they ALL-do, eventually...) but I could do nothing about it (...w/o voiding warranty etc) - then you're right back to Arctos-style 'handicaps', blech!

just my crazy opin...
cheers...

I think flecom is referring to the individual diode alignment
And jon your referring to rgb/ module alignment??
Fwiw , i havent had any issues with module alignment, and the green module in my kv, is floating on tec's (not even bolted down) to the baseplate...

[carlos3621]

Martin: how about posting at least , some retail pricing??

Hey C -

And jon your referring to rgb/ module alignment??

Well, yeah, but it's more about MM-1-drift and/or optical-drift from external thermal-effects.... which, with a totally-sealed 'RGB-brick'-style module, could be very-frustrating, if you could not access it, at all... Yours, yes, you can-access, at least, but you have to remove the top-cover, thus exposing all your modules-optics / dichros to dust / fog, etc...

Fwiw , i havent had any issues with module alignment

Well, #1, you don't do mostly graphics-shows.. and #2, even your sys - while, yes it is very tight / any drift is extremely slight - certainly not noticeable in aerial shows / fx - it *does* drift, with external-temp influences... try projecting several circles, squares and x-ed lines (...like #'s or +'s) all in one frame, in colors like: orange, purple, 'grey', etc, indoors - then take the box outdoors, some fairly cool-night, and watch the 'fringing' / dis-convergence appear after a time... ...especially: project for awhile, then leave it off for awhile (in the outdoor cool) then, project-again...

..yeah, it might be slight, but when you are projecting 'mission-critical' blended-colors (ie: a Client logo with shades of colors (dark yellow/orange, purple, grey, etc) you quickly-realize the benefit of having external-convergence controls - no need to take any covers-off - just a quick spank with an allen-key, and you're spot-on... ie:

(..the color-issues in the grey in this shot are due to modulation-timing diffs between dpss green and the direct R + B, but because the convergence was quickly easily externally-tweekable, that 'spot-onness' helped minimize those color-shift anomalies...)

...that's all I'm sayin / inquiring-about - the little Kv5 'brick' would be more attractive, with such-adjs, imo...

And actually, Dude, we could quite easily 'improve' your Kv-sys, with 'externally-adjustable / accessible' mounts - checkky these out:

http://www.thorlabs.us/NewGroupPage9...ctGroup_ID=227 (...though these, specifically, might be too-big for your box, dunno - there are smaller ones out there...)

...a few, precisely-placed holes in your top-cover (for access) with nice button-plugs, and then, no-need to take the top-cover off (...'cept for cleaning, once in awhile....) for simple, fog/dustless, onsite convergence-tweekage... Just an idea...

Not trying to start any riots, here, just think / submit that being *able* to tweek your convo, w/O having to get the optical-deck all nekkid, is just plain good-design...

ciao

Martin: how about posting at least , some retail pricing??

Its all on the synchrovision website in Martin's signature. Thats how I found how much it would be (at least the real world affordable ones were, I stopped looking after £2k...)

[pelosh]

Ok, so developers are "thinking it through" as I type. The module at the exhibition was working prototype only and not production unit.

I will update the info as soon as production is ready.
