Manual zoom


Brothers

Recommended Posts

Hi,

I would like to design the following fixture: (attached), equipped with manual zoom functionality. At each zoom step, I require distinct beam angles, outputs, etc. Could you advise me on how to implement this zoom feature or provide relevant information? Currently, my only idea is to create three lenses, each corresponding to a different zoom step.

Hello,

you can either create three separate devices if the light output is different for each lens. You can also virtual zoom, see example of this fixture, which does it the virtual zoom way:

No, this info would be for visualizer only. You could do it also by DMX mode, yes, then it would be more visible to the customer and also available in the visualization...

So I could do it with the "Virtual DMX", but I won't be able to modify the beam angles, outputs, etc. for each step.

You can modify the beam angles, that is the function of Zoom. If each lense has very different Lumen values, then you would use different files. If the lumen output is same, you could just use the modes or virtual zoom.

I have very different values so I'm going to do the 3 lens option(in the Geometry tab).

Thank you for your help.

Yep, makes sense. Then you can use a different DMX Mode for each lens (for example fresnel, profile, pc...). And if the lens can change angle but lumens remain the same, you can use the virtual zoom in there too.
