lens tube angles

Hi 

I have 50 Deg. fixed lens tubes on some Color Source V profiles. It's a little wide. I was wondering if folk had tried moving lenses about within the lens tube. Thinking I might try it in the 36 Deg slot.

Is this ok? Anyone experimented with this? Suggestions or warnings?

Thanks

Gareth

  • Never played around with this but:

    Just keep in mind that there is a lot of exact math that goes in the the emitter, reflector, lens, and lens tube. So, change any variable and all he math changes. Moving a 50 degree to a new slot changes several variables. 

    Possible issues

    Beam distortion: The beam may become blurry, uneven, or develop halos.

    Focus issues: You might not be able to achieve a sharp edge, no matter how you adjust the barrel.

    Hot spots or dim areas: Misalignment can cause uneven light distribution.

  • Gareth, the markings on the inside of the lens tube are for lens installation at the factory only and will not change the beam angle.  The beam is based on the lens itself and where it is placed, the markings just ensure that it's always placed in the right spot for the product.  If you need variable beam angles, I suggest purchasing separate tubes or looking at the zoom lens which replaces the shutter barrel and lens tube on your existing light engine.

    Thanks. Saved me a wasted afternoon !

    Good shout about hotspots etc.

  • Mari Galles, Technical Support Specialist told me in order to change a 50 to a 36....

    ColorSource V can use any of our lens tubes types, so we'll need to know if they have a standard, EDLT, or XDLT tube. If there's only one lens in it now, then it's standard and they'll need  2 lenses to make a 36deg. 7060A4021 would be the rear lens and 7060A4020 would be the front lens. 

    If there's only one slot marked as 36deg, then it's going to be too old to fit modern replacement lenses. if there are 2 50deg lenses in it, then it's not standard and we need to know what the labels on it say to identify it
