About This Original Lens

Optoma BX-CTA27 Long Zoom Lens

The BX-CTA27 Long Zoom is a long throw lens produced by Optoma. Its optical structure, lens coatings, and body tolerances are matched to the original projector specifications, ensuring immediate installation and stable imaging. For installation environments with limited projection distance (e.g., projecting a large image from a short distance, ultra-short throw close to the wall), selecting the correct throw ratio is more critical than choosing a universal lens.

This lens has a throw ratio of 7.20-10.80:1. 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 the on-site installation distance and screen size, then match it to this model.

Authenticity and Procurement Information

Zorsika supplies the Optoma original lens BX-CTA27 Long Zoom through authentic channels, complete with original packaging and verifiable serial numbers. It is suitable for bulk procurement and project supply for engineering projection, conference rooms, classrooms, and similar projects.

• Authenticity Guarantee: Sourced through official OEM channels, with original packaging and serial numbers. Bulk projects can request channel credentials to eliminate refurbished units and sources of unknown origin.
• Compatibility Verification: Provide the projector model number before ordering. Zorsika technical support will verify it against the compatible model list above to avoid installation issues.
• Project Supply: The BX-CTA27 Long Zoom covers 3 models. For common projects, scheduling can be arranged in advance to shorten lead times.
• Alternative Solutions: If budget is a concern, Zorsika can also provide alternative lenses with the same specifications. Key parameters are benchmarked against the original; choose as needed.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For large quantities, it is recommended to first obtain one unit for testing.

Frequently Asked Questions

Q: How to choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Optoma, with optical parameters and body tolerances calibrated to the original projector, suitable for projects with strict requirements for OEM 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 supplies both lines; choose based on project requirements.

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

A: Compatibility is based on the projector's lens mount and panel/chip size. This article lists verified compatible models. Engineering projectors from the same generation and brand often share mounts. If unsure, taking a photo of the projector's nameplate and sending it to Zorsika technical support for confirmation is a safer approach.

Q: How do I choose the throw ratio?

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

Q: How can I ensure the BX-CTA27 Long Zoom is authentic?

A: Zorsika supplies authentic products from OEM channels, complete with original packaging and verifiable serial numbers. For bulk projects, channel credentials can be requested to ensure the units are not refurbished or second-hand salvage parts.

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

A: Before disassembly, ensure the projector is powered off and wait for the cooling fan to stop. Handle the lens by the barrel, avoiding contact with the glass elements. Use a blower to gently remove any dust. After installation, perform a focus test before tightening the mounting screws, and clean the mount and contacts while you're at it.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the date on the shipping documents.
