About This OEM Lens

Christie 121-112105-XX Zoom Lens

The 121-112105-XX Zoom is a standard throw lens manufactured by Christie as original equipment. 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 restricted projection distances (e.g., large images from short distances, ultra-short-throw wall-mounted setups), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens offers a throw ratio of 1.20-1.80:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in compact 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 do I choose between an OEM lens and a replacement lens?

A: OEM lenses are manufactured by Christie 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, offering advantages in budget and lead time. Zorsika supplies both options—choose based on your project requirements.

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

A: Verify based on the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share common mounts. If unsure, photograph the unit's nameplate and send it to Zorsika technical support for confirmation—this is the safest approach.

Q: How do I choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value yields a larger image (short-throw/ultra-short-throw for compact spaces at close range), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the 121-112105-XX Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers. For bulk projects, channel documentation can be requested to ensure the lens is not refurbished or a used disassembled unit.

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

A: Before removal, power off the projector and wait for the cooling fan to stop. Hold the lens by the barrel without touching the glass; use a blower for dust. After installation, test focus first, then tighten 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-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.
