The Rebeam Dome Optic 184° for Vivitek D89 Lens Series is a telecentric, fixed focal length lens engineered for professional fulldome projection. Designed for compatible Vivitek 0.80" 1‑chip DLP projectors with the D89 lens mount, it delivers a maximum vertical projection angle of 184° to cover full hemispheric domes with a single projector. With a 3.5 mm focal length, fast F2.2 aperture and manual focus from 600 mm to infinity, it supports crisp, even imaging across curved surfaces.
Optimised for 0.8" panels, the 10.8 mm image circle and tight optical control provide balanced detail, with centre/edge MTF of approximately 66%/60% at 67 lp/mm, lateral chromatic aberration under 4 µm (R–G) and under 2 µm (B–G), and F‑Theta distortion up to -1%. A robust metal‑glass construction (approx. 122 × 285 mm) ensures reliability in demanding, continuous‑use environments.
Ideal for planetariums, science centres, museums and immersive experiences, the lens requires precise alignment plus projector-specific calibration and warping to achieve accurate geometry on curved screens.
