Zorsika SC291 Projector Lens — Compatible with 6 Models

The projector lens directly determines the image size and clarity. The SC291 covers 6 Appotronics models; check the compatibility list before replacing the lens.

Specifications of This Lens

The above specifications are from the Zorsika product database. For the full technical datasheet, please contact our sales team.

Compatibility: List of 6 Models (with Specifications)

The following are the verified compatible models for the SC291 (Appotronics projectors), each with brightness, resolution, and zoom ratio:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (refer to the model nameplate/user manual for accuracy); lens compatibility is determined by the projector's mount interface and optical structure. For models not listed, contact Zorsika technical support for confirmation.

Why Choose Zorsika

Zorsika offers the SC291 as a same-spec replacement lens matching the original, with key parameters benchmarked against the OEM version, supporting bulk project procurement and supply.

Zorsika same-spec replacement model, compatible with Appotronics AL-SH10K, AL-SU10K, AL-SU12K, AL-SU13K, AL-SU15K, and 6 other models; enter SC291 in the Zorsika website query system to view the full compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens groups matched to OEM specifications
• Resolution Testing: Each unit tested before shipment, MTF data available
• Coating Process: Lens coatings at the same level as OEM, reducing light loss
• Stable Supply: Supports bulk procurement and project supply

In short: The lens is the optical core—don't gamble with image quality over price differences. Zorsika projector lenses are manufactured to OEM drawings, offering a comprehensive advantage.

Note: Actual imaging performance is affected by projector condition and installation environment; we recommend testing 1 unit before bulk procurement.

What to Watch Out for When Replacing the Lens?

• Power Off Before Replacement: Turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface.
• Don't Touch the Glass: Fingerprints and oil can directly affect image quality; hold the lens barrel, not the glass; use a blower for dust, never wipe with a dry cloth.
• Focus Before Tightening: After installation, test focus first, then tighten the locking screws to prevent image drift from loosening over time.
• Keep the Interface Clean: Dust on the mount and contacts can cause poor connection; clean them when replacing the lens for reliability.

Frequently Asked Questions

Q: My projector isn't in the 6 models listed above. Can I use the SC291?

A: The list covers verified models, not all possibilities. Projectors of the same brand and generation often share lens mounts; send a photo of the nameplate and original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the original one?

A: The lens is the core of the projection optical path, directly determining clarity and color. Zorsika lenses (model in the spec table above) are benchmarked against OEM optical parameters (focal length, throw ratio, lens groups), with consistent coating processes, delivering sharp images with no edge blur; ordinary replacement lenses often use standard glass with insufficient coating layers, making brightness loss and color shift obvious. For engineering and exhibition scenarios, Zorsika is the recommended choice.

Q: Why choose Zorsika over the original?

A: Zorsika lenses are manufactured to OEM optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each unit undergoes resolution testing before shipment. Compared to OEM, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is data-backed.

Q: What if the lens doesn't match the image size?

A: First confirm the projector's lens mount and optical axis position, then select a lens with the appropriate throw ratio based on the actual installation distance; if unsure, send the installation distance and screen size to Zorsika technical support, and we'll recommend the right option.

Q: Is there an installation guide for the SC291?

A: Yes. The lens removal and installation steps for Appotronics models are largely similar; contact Zorsika sales to get illustrated or video instructions for your specific model.

Q: What is the warranty period for the lens?

A: All Zorsika projector lenses come with a 12-month warranty; for normal use and non-man-made damage (e.g., impact, water damage, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping document date.
