SL-129 Compatible Projector Models (2 Models with Brightness/Resolution)

The following are verified compatible models for the SL-129, each with brightness and resolution; the applicable lens model for all is SL-129:

Note: Brightness/resolution data is from the model database (refer to the unit's nameplate/manual for accuracy); lens compatibility is determined by the projector's lens mount and panel/chip size. For models not listed, please contact Zorsika technical support for confirmation.

About This Original Lens

The SL-129 is an original Long Throw lens manufactured by Digital Projection. Its optical structure, lens coatings, and body tolerances are matched to original machine standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-distance large images, ultra-short throw against walls), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens features a throw ratio of 2.56-4.16:1 (Long Throw Zoom). 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 your installation distance and screen size, then match it to this model.

FAQ

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

A: Original lenses are manufactured by Digital Projection, with optical parameters and body tolerances calibrated to original machine standards, making them ideal for projects with strict OEM consistency requirements. Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original machine, offering advantages in budget and lead time. Zorsika supplies both options; choose based on your project requirements.

Q: How do I confirm this lens works with my projector?

A: Compatibility is determined by the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share the same mount. If unsure, photograph the unit'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 throw/ultra-short throw suits close-range small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model's focal length range.

Q: How can I ensure the SL-129 is genuine?

A: Zorsika supplies genuine products through OEM channels, complete with OEM packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure the lens is not refurbished or a used pull.

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

A: Before removal, ensure the projector is powered off and the cooling fan has stopped; hold the lens barrel without touching the glass, use a blower for dust; after installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty on all projector lenses; for normal use and non-human damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly. The warranty period is based on the shipping invoice date.
