Dioptra Parabolic 133
Tax included where applicable. Delivery, rigging and commissioning arranged by your concierge.
ELVARNIXO Shaping — light is made at the last metre
The Dioptra is the portrait engine of the modern studio: a true parabolic curve on an indexed rod, travelling from specular bite to wrapped glow with a note-taking level of repeatability.
Light is shaped at the last metre, so the last metre gets the best materials: silver and white textiles woven and measured for even spread, diffusion in graded weights that stay neutral, and frames that open in seconds and survive years of vans. Every modifier is measured on our photometric bench — the beam pattern in the listing is the beam pattern in the box.

- Frames open in seconds and forgive the two-hundredth assembly
- Textiles woven and graded for neutral colour after years of vans
- Every panel, rib and layer stocked as a part for fifteen years
- Sixteen or twenty-four ribs holding a true parabolic curve
- Silver keeps its colour; ribs replace one by one
- Indexed focusing rod — note the number, repeat the look

Questions, Answered
How repeatable is the focus effect on the parabolics?
The rod is indexed — note the number, repeat the look. Beam maps at three rod positions ship in the box.
Which mount does it fit?
S-type as standard, with speedrings for the major systems listed in the options. Tell the concierge your fixtures and we confirm fitment before dispatch.
The ELVARNIXO Promise
Every ELVARNIXO fixture ships with its own photometric and colour report — CRI, TLCI and SSI measured on our Prague bench for that serial number, not copied from a brochure.
