Jammie300 Posted April 29, 2008 Share Posted April 29, 2008 yeh I used a load of these on a show few years ago, they fit on par 16 cans and the two lens' allow you to focus the gobo, is quite q clever idea.....nothing to stop a bigger version of this being created for 64's etc... Stuart Maybe the sheer cost of creating a huge lens for the 64. Thats what stopping larger versions being created Link to comment Share on other sites More sharing options...
Tomo Posted April 29, 2008 Share Posted April 29, 2008 Maybe the sheer cost of creating a huge lens for the 64.Or more accurately, the fact it won't work. This method works for MR16 lamps because they are almost a point source - they have very tiny and compact filaments.The point source allows very simple optics to result in reasonable gobo projection - in fact, you get a reasonably sharp images with no optics at all.The lens is there to limit spread and to make it possible to vary the size of the beam. PAR64s have much bigger filaments for fairly obvious reasons. This means that they aren't anything like a point source, and will always have soft edges.- Look at the beam from a CP60!

musht Posted April 29, 2008 Share Posted April 29, 2008 Ikea Isbrytares are great, with a tube of congo blue round them , they leak. Roscoe or Opti kinetics once made an image projection doo-dah for a `64 , used some sort of fresenl lens and took huge and expensive Cibachromes , wasnt very bright and was very expensive as far as remember.

church Posted April 30, 2008 Share Posted April 30, 2008 I once needed an effect on the stage of light coming through an overhead grating and showing the pattern of the grating on the stage. As an act of desperation I tried three old 8 inch diameter stepped lenses of some old profiles on the front of long nosed PAR 64s. Much to my surprise I got a nice projection of the safety mesh in front of the lamp on the stage floor. I used three of these and it worked well. Pure luck. The same principle as the par16 projector mentioned above. Link to comment Share on other sites More sharing options...
rossmck Posted June 2, 2008 Share Posted June 2, 2008 Didn't Altman do a fixture (Mini Eclipse) or something which was essentially an MR16-based Profile with integral transformer? Link to comment Share on other sites More sharing options...
church Posted June 2, 2008 Share Posted June 2, 2008 True Altman did indeed - and still do - sell an version of the Mini Ellipse that is based on the MR16 lamp and attaches to track lighting Link to comment Share on other sites More sharing options...
Genus Posted June 2, 2008 Share Posted June 2, 2008 Also, the selecon aureol does exactly the same thing, it's an MR16 lamp with a couple of lenses in front and a gate for gobo purposes. http://www.ardiislight.com/products/aureol/beam-shaper.html Genus Link to comment Share on other sites More sharing options...
