Projection without limits

The right lens opens more opportunities

A smarter projection strategy starts with the lens.

Optoma’s interchangeable lens range — led by the BX‑CTA28 ultra-short throw lens — helps organisations adapt to different environments without redesigning the system or replacing the projector.

With 10 interchangeable lenses covering a 0.34 to 8.6:1 throw ratio range, you can standardise the platform, reduce complexity and unlock more commercial and creative possibilities.

The Lens Is the Strategic Tool

In projection planning, the lens is often treated as a finishing detail.

In reality, it can be one of the most important decisions in the entire system.

A lens-led strategy helps organisations:

  • Deploy faster

  • Reduce project risk

  • Lower operational complexity

  • Scale more easily across multiple environments

  • Adapt to different spaces without redesigning the system or purchasing a new projector

    A lens is not an accessory. It is a strategic part of the solution.

BX‑CTA28: The Lens That Changes What’s Possible

The BX‑CTA28 ultra-short throw lens is designed to help solve that challenge by enabling large, high-impact visuals in close-range environments. It is ideal for immersive environments, exhibitions, creative installations and more.

Key value points

  • Makes close-range projection more practical

  • Helps reduce design compromise in constrained spaces

  • Supports more commercially and creatively viable installations

  • A key strategic lens within the wider interchangeable range

Why a Lens-Led Strategy Makes Commercial Sense

Why a Lens-Led Strategy Makes Commercial Sense

A stronger lens strategy does more than improve technical flexibility. It creates operational and commercial value.

Adapt to More Environments

A flexible lens strategy allows one platform to work across more environments, more efficiently.

Tight spaces and close-range projection

Where the BX‑CTA28 helps unlock impact in constrained environments.

Immersive rooms

Create high-impact projection in spaces where placement flexibility matters.

Exhibition design

Adapt to unusual layouts and changing environments more easily.

Retail and digital signage

Support adaptable, visually impactful displays without being limited by fixed screen positions.

Live events

Respond to venue changes and deployment pressures with greater flexibility.

Auditoriums and professional environments

Scale across venues and spaces while keeping the platform more consistent.

Lens Strategy in Action

See how a lens-led approach can help solve real-world installation and design challenges.

From immersive applications and exhibitions to professional environments, a stronger lens strategy can deliver better outcomes before installation even begins.

A Standardised Platform Behind the Lens Strategy

A flexible lens strategy works best when built on a stable projection platform.

The ProScene ZK1000, ZK1120 and ZK1320 provide that consistency. Rather than requiring a different projector for every environment, organisations can standardise their projection platform and adapt through interchangeable lenses.

That means:

  • A more consistent hardware foundation

  • Simpler support and deployment

  • Better scalability across environments

  • More value from the same platform

  • Optoma Management Suite compatibility for simplified control, monitoring and diagnostics

The platform stays consistent. The lens does the adapting.
