About This Original Lens
Optoma BX-CTA22 Long Zoom Lens
The BX-CTA22 Long Zoom is a long throw lens produced by Optoma's original factory. Its optical structure, lens coatings, and body tolerances are matched to the original machine's 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 2.00-4.00:1. 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 Optoma original lens BX-CTA22 Long Zoom through authorized channels, supplied with original packaging and a verifiable serial number. It is suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and similar projects.
- Authenticity Guarantee: Sourced through official OEM channels, with original packaging and serial number. 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-CTA22 Long Zoom covers 9 models. For common projects, schedule in advance to shorten lead times.
- Alternative Solutions: If budget is a concern, Zorsika can also provide alternative lenses with equivalent specifications, with key parameters matching the OEM. 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: The original lens is produced by Optoma's original factory, with optical parameters and body tolerances calibrated to the original machine, 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 machine, offering advantages in budget and lead time. Zorsika supplies both lines; choose according to 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, it's safer to take a photo of the projector's nameplate and send it to Zorsika technical support for confirmation.
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 this model's focal range.
Q: How can I ensure the BX-CTA22 Long Zoom is authentic?
A: Zorsika provides authentic products from OEM channels, with original packaging and a verifiable serial number. Bulk projects can request channel credentials to ensure the units are not refurbished or second-hand parts.
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 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 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), contact after-sales service directly. The warranty period is based on the shipping document date.
