Does IMAX Have 3D Screens? Debunking Common Misconceptions

Often, the debate around IMAX screens revolves around whether they truly have 3D capabilities. This article aims to clarify these misconceptions and provide a detailed explanation of the technologies used in IMAX and its related systems.

Projector Technology vs. Screen Technology

Contrary to popular belief, the screens themselves in IMAX theaters are not the primary reason for the absence of 3D projection. The key lies in the projector technology used within the theater.

Originally, IMAX film projectors were designed to handle a single strip of film and only project 2D movies. However, it was discovered that 3D movies work exceptionally well on IMAX screens, leading to the development of 3D capable projectors.

Early 3D IMAX Theaters

The first 3D IMAX theater was introduced at Expo '86 in Vancouver, British Columbia. This innovative setup involved placing two IMAX projectors side by side, each projecting a different layer of 3D film. This method allowed for the display of 3D content on the immersive IMAX screen.

Later Developments in IMAX Projector Technology

As IMAX technology advanced, newer projectors were designed with two lenses and dual film paths, enabling them to project either 2D or 3D content. These projectors, known as "MPX" projectors, are commonly used in multiplex-theater conversions, making them 3D capable.

When IMAX began to provide electronic projectors, all systems were inherently capable of 3D projection. Although the specific technologies used may vary, all modern electronic projection systems can successfully display 3D content.

Differences Between Flat-Screen and Dome-Screen IMAX Theaters

It's important to note that there are different types of IMAX screens, primarily flat-screen and dome-screen projects. Here's a breakdown of the capabilities of each:

Flat-Screen IMAX Theaters: The vast majority of flat-screen IMAX theaters are equipped with 3D projection capabilities. Only a few older film projector systems are not capable of handling 3D content. DOMEScreen Projectors (OMNIMAX or IMAX Dome System): These theaters predominantly use 2D projection, with both film and electronic projectors. While there was once a 3D dome system called IMAX SOLIDO, it is no longer in operation.

Conclusion

In summary, while there are some variations in capabilities between flat-screen and dome-screen IMAX theaters, the overwhelming majority of flat-screen IMAX theaters are capable of 3D projection. Only a handful of older film projector systems may not support 3D. Dome-screen IMAX theaters, on the other hand, are mostly 2D, though they do not inherently lack 3D capabilities.
