About This Original Lens

The SL-121 is an Ultra Short Throw lens manufactured by Digital Projection. Its optical structure, lens coatings, and housing tolerances are all matched to original equipment standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., large images from short distances, wall-mounted ultra-short-throw setups), choosing the right throw ratio is more critical than selecting a generic lens.

This lens has a throw ratio of 0.37:1 (Fixed, UST). Throw ratio = projection distance ÷ image width: a smaller value means a larger image (ideal for short distances and small spaces), while a larger value requires a longer installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model.

FAQ

Q: How do I choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Digital Projection, with optical parameters and housing tolerances calibrated to original equipment standards, making them ideal 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 matched to the original, 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: 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, 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 means a larger image (short-throw/ultra-short-throw is ideal for short distances and small spaces), while a larger value requires a longer installation distance. Work backward from your installation distance and screen size to determine the required throw ratio range, then match it to this model's focal length.

Q: How can I ensure the SL-121 is genuine?

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

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

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