ST1 Zoom Compatible Projector Model List (2 Models, with Brightness/Resolution)

The following are verified compatible projector models for the ST1 Zoom, each with brightness and resolution; the compatible lens model for all is ST1 Zoom:

Note: Brightness/resolution data is taken from the model database (subject to the nameplate/manual on the projector body); lens compatibility is based on the projector's lens mount and panel/chip size. For models not on the list, please contact Zorsika technical support for confirmation.

About This Original Lens

Optoma ST1 Zoom Lens

The ST1 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 specifications, ensuring plug-and-play 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 1.45-1.95:1. 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 & Procurement Information

Zorsika provides authentic Optoma original lens ST1 Zoom through authorized channels, complete with original packaging and verifiable serial numbers, suitable for bulk procurement and project supply for engineering projectors, conference rooms, classrooms, and other projects.

• Authenticity Guarantee: Sourced through official OEM channels with original packaging and serial numbers. For bulk projects, channel credentials can be provided upon request to eliminate refurbished units or sources of unknown origin.
• Compatibility Verification: Provide the projector model before ordering. Zorsika technical support will verify it against the compatible model list above to ensure proper fit.
• Project Supply: The ST1 Zoom covers 2 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 OEM product; choose 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 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 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, imaging circle, and mount benchmarked against the original, offering advantages in budget and lead time. Zorsika can supply both lines; choose based on 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. 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 more reliable.

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 ST1 Zoom is authentic?

A: Zorsika provides authentic products from OEM channels, complete with original packaging and verifiable serial numbers. For bulk projects, channel credentials can be provided upon request 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, be sure to turn off the projector 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 (e.g., impact, water ingress, unauthorized disassembly), you can directly contact after-sales service. The warranty period is based on the date on the shipping documents.
