About This Original Lens

Optoma BX-CTA10 Short Zoom Lens

The BX-CTA10 Short Zoom is a short throw lens manufactured by Optoma. Its optical structure, lens coatings, and housing tolerances are all matched to original equipment standards, ensuring plug-and-play installation and stable imaging performance. For installation environments with limited projection distance (e.g., large images from short distances, ultra-short throw wall-mounted setups), selecting the correct throw ratio is more critical than choosing a generic lens.

This lens has a throw ratio of 0.50-0.65:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for close-range, compact 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 a replacement lens?

A: Original lenses are manufactured by Optoma, with optical parameters and housing tolerances calibrated to the original equipment, making them ideal for projects with strict requirements for OEM consistency. Zorsika replacement lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original unit, 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: Compatibility is determined by the projector's lens mount and panel/chip size; verified compatible models are listed in this article. Projectors from the same brand and generation often share the same mount. If uncertain, photograph the unit's nameplate and send it to Zorsika technical support for confirmation.

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 suits close-range, compact 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-CTA10 Short Zoom guaranteed to be genuine?

A: Zorsika supplies genuine products through official manufacturer channels, with original packaging and traceable serial numbers; channel documentation can be requested for bulk projects to ensure the lens is not refurbished or a used disassembled unit.

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

A: Before disassembly, ensure the projector is powered off and the cooling fan has stopped; hold the lens by the barrel without 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 you go.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty; for normal use and non-man-made damage (e.g., impact, water damage, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
