The following are verified compatible projector models for the SL-122, each with brightness and resolution; the applicable lens model for all is SL-122:

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

About This Original Lens

The SL-122 is an original standard throw lens manufactured by Digital Projection. Its optical structure, lens coatings, and body tolerances are all 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, wall-mounted ultra-short throw), choosing the right throw ratio is more critical than selecting a universal lens.

This lens offers a throw ratio of 0.65-0.85:1 (UST zoom). Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a longer 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 do I choose between an original lens and a replacement 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 requirements for OEM consistency. Zorsika replacement 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 can supply both options; choose based on your project requirements.

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

A: Check the lens mount and panel/chip size on the projector; this article lists verified compatible models. Projectors of the same generation and brand often share the same mount. If unsure, take a photo of the nameplate and send it to Zorsika technical support for confirmation.

Q: How do I 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 longer installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the SL-122 is genuine?

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

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

A: Before removal, turn off the projector and wait for the cooling fan to stop; hold the lens barrel without touching the glass, use a blower for dust; after installation, focus-test before tightening the locking screws, and clean the mount and contacts as you go.

Q: How long is the lens warranty?

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