Projector Lens OPTOMA BX-CTA13 Extra Long Throw Lens (SP.72N13GC01)

OPTOMA BX-CTA13 Extra Long Throw Lens is an interchangeable projection lens designed for compatible OPTOMA fixed-install projectors. It provides an extended throw capability to project large images from long distances, suitable for auditoriums, lecture halls and large venue installations where screen placement and projector mounting require a longer projection distance. The lens is engineered to maintain image clarity and uniformity across large screen sizes when used within its optical range.

Advantages

This extra long throw lens gives integrators the flexibility to position projectors farther from the screen while still achieving the required image size. It is manufactured to match OPTOMA optical standards, helping to preserve focus accuracy and image uniformity. The lens supports straightforward installation into compatible projector models and reduces the need for repositioning or additional mounting hardware in long-throw setups.

Suitable for

• Large auditoriums and lecture theatres
• Conference centres and exhibition halls
• Fixed-install venue setups with constrained mounting locations
• Applications requiring large screen projection from long distances

Key specifications

• Optical type: Extra long throw projection lens
• Compatibility: Designed for use with compatible OPTOMA fixed-install projector models
• Use case: Fixed-install and venue installations requiring extended throw ratio
• Image performance: Engineered for maintained focus and uniformity across large screens
• Mounting: Interchangeable lens for projectors with compatible lens bay

How to use

Install the lens into the compatible OPTOMA projector following the projector manufacturer's lens-change procedure. Secure the lens in the projector’s lens bay and perform mechanical and optical alignment according to installation guidelines. Use the projector’s focus and zoom controls (if available) to achieve sharp image geometry on the target screen. Verify image uniformity and keystone correction from the final mounting position and make fine adjustments as required.

Usage recommendations

Confirm projector model compatibility before installation and ensure the installation environment allows the required throw distance. For permanent installations, perform a test projection during setup to verify screen coverage and focus across the image plane. Use secure mounting hardware and follow local safety regulations for ceiling or wall installations.
