About This Original Lens

Optoma BX-CTA25 Zoom Lens

The BX-CTA25 Zoom is a Standard Throw lens produced by Optoma's original factory. Its optical structure, lens coatings, and body tolerances are matched to the original projector standards, ensuring ready-to-use 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 0.85-1.02:1. 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 provides authentic supply channels for the Optoma original lens BX-CTA25 Zoom, complete with original packaging and verifiable serial numbers, suitable for bulk procurement and project supply for engineering projectors, meeting rooms, classrooms, and other 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-CTA25 Zoom covers 2 models. For frequently used projects, scheduling in advance can shorten lead times.
• Alternative Solutions: If budget-sensitive, Zorsika can also provide alternative lenses with the same specifications, with key parameters matching the OEM, for selection as needed.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For large bulk orders, it is recommended to first obtain 1 unit for actual testing.

Frequently Asked Questions

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

A: Original lenses are produced by Optoma's original factory, 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 projector, offering advantages in budget and lead time. Zorsika can supply both lines; choose according to project requirements.

Q: How can I confirm if 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 of 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 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-CTA25 Zoom is authentic?

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

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

A: Before disassembly/assembly, be sure to power off the projector and wait for the cooling fan to stop. Handle the lens by the barrel, avoiding touching the lens elements. Use a blower to gently remove any dust. After installation, perform a focus test first 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 offers a 12-month warranty for all projector lenses. For normal use and non-human-caused damage (such as impact, water ingress, or unauthorized disassembly), you can directly contact after-sales service. The warranty period is based on the date on the shipping documents.
