About This Original Lens

Optoma BX-CTA26 Zoom Lens

The BX-CTA26 Zoom is a Standard Throw lens produced by Optoma. Its optical structure, lens coatings, and mechanical 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 generic lens.

This lens has a throw ratio of 1.20-1.73:1. 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 authentic Optoma original lens BX-CTA26 Zoom through authorized channels, with original packaging and verifiable serial numbers, suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and other applications.

• Authenticity Guarantee: Sourced through official OEM channels, with original packaging and serial numbers. Bulk projects can request channel credentials to eliminate refurbished units or sources of unknown origin.
• Compatibility Verification: Provide the projector model before ordering; Zorsika technical support will verify against the compatible model list above to avoid installation issues.
• Project Supply: The BX-CTA26 Zoom covers 2 models. For frequent projects, schedule in advance to shorten lead times.
• Alternative Solutions: If budget-sensitive, Zorsika can also provide alternative lenses with equivalent specifications, with key parameters matching the OEM, for selection based on needs.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For large bulk orders, 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: The original lens is manufactured by Optoma, with optical parameters and mechanical 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 options; choose based on project requirements.

Q: How to confirm if this lens is compatible 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 of the same generation and brand often share mounts. If unsure, taking a photo of the projector nameplate and sending it to Zorsika technical support for confirmation is more reliable.

Q: How to choose the Throw Ratio?

A: Throw Ratio = Projection Distance ÷ Image Width. A smaller value produces a larger image (short/ultra-short throw 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 to ensure the BX-CTA26 Zoom is authentic?

A: Zorsika supplies authentic products through OEM channels, with original packaging and verifiable serial numbers. Bulk projects can request channel credentials to ensure the units are not refurbished or second-hand.

Q: What should I pay attention to when replacing the 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 lens elements. Use a blower to gently remove 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 shipping document date.
