About This Original Lens

Optoma BX-CTA03 Zoom Lens

The BX-CTA03 Zoom is a Long Throw lens manufactured by Optoma. Its optical structure, lens coatings, and housing tolerances are matched to original equipment standards, ensuring plug-and-play installation and stable imaging. For installations with restricted projection distances (e.g., short-distance large images, ultra-short throw near walls), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 1.52-2.92:1. Throw ratio = Projection Distance ÷ Image Width: a smaller value produces a larger image (suitable for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model.

FAQ

Q: How do I choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Optoma, with optical parameters and housing tolerances calibrated to the original machine, suitable for projects with strict requirements for original consistency. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matching the original, offering advantages in budget and lead time. Zorsika can supply both options; choose based on your project requirements.

Q: How can I confirm this lens works with my projector?

A: Refer to the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share mounts. If unsure, sending a photo of the unit's nameplate to Zorsika technical support for confirmation is the safest approach.

Q: How do I choose the throw ratio?

A: Throw ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short-throw/ultra-short-throw suitable for close-range small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model's focal length range.

Q: How is the BX-CTA03 Zoom guaranteed to be genuine?

A: Zorsika provides genuine products through manufacturer channels, complete with original packaging and traceable serial numbers. For bulk projects, channel documentation can be requested to ensure the product is not refurbished or a used pull.

Q: What should I pay attention to when replacing the lens?

A: Before removal, ensure the projector is powered off and the cooling fan has stopped. Hold the lens by its barrel, avoid touching the glass, and use a blower for dust. After installation, perform a focus test before tightening the locking screws, and clean the mount and contacts as a routine step.
