    Yep. I'm loving my Kvant 1.7 w/CT's too. About three more would be nice!

    welcome to the forum miro
    funny the guy i work with has the same first name as you miroslav , he too is from the same country as you
    When God said “Let there be light” he surely must have meant perfectly coherent light.

    how would you compare the LM scanners to CT? i had the option to go with more power or better scanners so i chose scanners because with small powers under 3W they're not very suitable for outside beamshows anyway

    In my opinion and in my experience with my 2.1W kvant with LM's, LM's are good at up to around 28K (they're rated for 25K) and will draw absolutely perfect ILDA patterns and graphics up to that speed. They also produce very good beam show results.

    However, you can see the difference with CT's. If I were to compare my LM's to Jem's CT in his previous projector, then I'd say the CT's appear noticeably sharper in beam shows.

    However, the average man on the street would never notice the difference, its only if you've seen one then have the other to compare it to.

    That said I plan to upgrade my LM's for Pangolin scanners as and when they are proven, become available and money allowing.

    hm that's about what LW-50k would do (27k), what's the scan angle with those? because i couldn't find any info other than what's mentioned in Kvant materials
    with LW-50k the advertised scan angle is +/- 60 but in reality it's more like 40-45

    oh no... please don't let bill benner see this, or we' ll have another quest for facts on our hands

    (just joking of course, i don't want to fuel a fire. just some giggles!)

    When I say 28K that's projecting the 8 standard ILDA patterns that come with QS at 8 degrees with perfect reproduction. I think they're rated for ILDA at 25K but mine will do 28k in recent tests.

    Scanning max for the LM1 scanners is +or- 40 degrees according to Martin's web page and they can do 30K at 5 degrees according to information on there:

    One important factor to consider when looking at scanners is repeatability... For shows involving target mirrors nothing will beat Cambridge scanners for hitting the exact same spot time after time...

    I was involved in an installation in London which has two 7 Metre by 200 mm mirrors that rotate to thirty different positions and a laser beam is fired from around ten metres away to hit the very corner of each mirror and bounce off (http://www.photonlexicon.com/forums/...ight=porn+star)... This installation has been running for 6 months and the laser has not missed its target once... I would only use Cambridge for such a project and they CT6215hp) have proven to be spot on... I doubt there are many scanners that can do that...

    So while high speed and big angles are nice to have, repeatability can be important too...
