This Rebeam fulldome optic is engineered for Panasonic 0.80-inch 1‑chip DLP projectors using the ET‑C1 lens mount, delivering an extreme 184° maximum vertical projection angle for single‑projector dome coverage. The telecentric fixed lens features a 3.5 mm focal length, F2.2 aperture and manual focus, supporting uniform, high‑quality imaging across curved surfaces. Designed for professional dome applications, it provides an image circle of 10.8 mm tailored to 0.8-inch panels, with MTF performance of 66% at centre and 60% at edge at 67 lp/mm. Lateral chromatic aberration is tightly controlled (<4 µm R‑G, <2 µm B‑G) and F‑theta distortion is within −1%, helping maintain accuracy and consistency across the field. The robust metal‑glass construction measures approximately 122 × 285 mm and is built for long‑term reliability in demanding environments. Focus range is 600 mm to infinity. Precise alignment, projector calibration and warping are required to achieve correct geometry on immersive domes. Ideal for planetariums, science centres, museums and other immersive visualisation venues.
