Martin VDO Dotron Lens Array Narrow

A VDO Dotron with a diffuser on it is a bead of light with a very wide spread. Fit the Lens Array Narrow instead and the same dot becomes a beam: output is collected and pushed forward, which is what makes a grid of Dotrons read as a field of individual shafts through haze rather than a sheet of glow.

It clips into the same front position as the flat and dome diffusers, so an array can be switched between wash and beam looks without touching the rigging or the cabling. Order one per dot. Martin lists it as P/N 91611808.
