The projection angle describes how far the image extends beyond the field of view. In certain setups, 184° can provide a bit more leeway for coverage and mapping. Which option is right depends on the dome geometry, mounting position and content pipeline.
Dome lenses for fulldome projection
Choose your dome lens based on DMD chip size and projection angle. Buy directly in the shop or have your setup checked for technical compatibility in advance.
Dome lenses for dome projections & immersive installations: fulldome, museums, planetariums and more
Dome lenses are designed for professional fulldome applications where a wide field of view, controlled distortion and stable image quality are the priority.
- Planetariums and fulldome cinemas: immersive 180° and 184° projection, repeatable geometry
- Museums and science centres: robust installation, consistent image over long operating periods
- Education and research: visual communication, simulations, training environments
- Simulation and training: reliable projection for technical content and scenarios
Dome lenses are typically used in DLP setups. LCD and 3LCD may be an option depending on the projector, optical path and mechanical interface — this must be assessed case by case. Note: If you are using an LCD or 3LCD system, please send us the projector model and details of your installation. We will then check whether a suitable solution is possible.
If you briefly share the dome diameter, projector model and setup type, we will check compatibility in a structured way.

Single, dual or multi: which setup are you planning?
The right dome lens doesn’t depend on the DMD alone. What also matters is how many projectors you’re using and what your optical setup looks like.
Single setup
(1 projector)
Key factors for selection:
- Projection angle (180° or 184°)
- Dome diameter and projection distance
- Mechanical interface on the projector (mount, adapter, installation situation)
Dual setup
(2 projectors)
Key factors for selection:
- Symmetry of the setup and identical optics per channel
- Overlap zones and planned blending
- Mounting positions and mechanical repeatability
Multi setup
(multiple projectors)
Key factors for selection:
- Consistent optical parameters across all channels
- Distortion profile and system-wide calibratability
- Tolerances for focus, centring and alignment

Image quality in a dome starts with the optics
In fulldome setups, every optical compromise shows up directly on the surface. The lens affects not only the image framing, but also the technical quality across the entire field of view.
- Sharpness and MTF: A dome lens must deliver detail contrast across the field, not just in the centre.
- Distortion and calibratability: Fisheye projection needs a stable distortion profile so that warping and mapping work cleanly.
- Colour stability and chromatic effects: Optical colour fringing becomes visible in a dome, especially at edges and in bright transitions.
- Focus and field curvature: Even focus across the surface is more important in a dome than in classic flat-screen projection.
- Practicality in operation: Mounting, centring and repeatability matter — especially for dual and multi setups.
The lens is a key component in the optical chain. When DMD, angle, mount and setup all match, planning becomes easier and operation more stable.
In our range you’ll find high-quality dome lenses for professional projectors from leading manufacturers — available to buy or rent.
Find the right dome lens in 3 steps
- Identify the DMD and chip size: Start with the chip size or the exact projector model. This narrows down the suitable lens families and helps avoid the wrong choice.
- Clarify projection angle and setup: Define whether you need 180° or 184°, and whether you’re planning a single, dual or multi setup. This determines requirements for distance, mounting and calibration.
- Verify compatibility: Check the mount, the optical installation situation and the parameters that are critical for image quality and operation. If you like, we can do this check based on the details you provide.

Frequently asked questions about dome lenses
The most important details are the projector manufacturer and model, the setup type (single, dual, multi), and basic geometry data such as dome diameter and mounting position. If you know the DMD chip size, that helps us match the right lens more quickly.
In some cases, yes. It depends on the optical path, mount and mechanical integration. Send us your projector model and we’ll check whether a suitable combination is possible.
Yes. International shipping is available. Costs and delivery times depend on the destination country and the shipping method selected.
