About This Original Lens

Christie 121-128102-XX Fixed Lens

The 121-128102-XX Fixed is an ultra short throw lens manufactured by Christie, with optical construction, lens coating, and housing tolerances all matched to original equipment standards—ready for installation with stable imaging performance. For installations with limited throw distance (such as short-throw large image projection, wall-mounted ultra short throw applications), selecting the right throw ratio is more critical than choosing a general-purpose lens.

This lens features a throw ratio of 0.38:1. Throw ratio = projection distance ÷ image width: smaller values produce larger images (suitable for short distances in compact spaces), while larger values require greater installation distances. Calculate the required throw ratio range based on on-site installation distance and screen dimensions, then match it to this model.

Frequently Asked Questions

Q: How to choose between OEM and alternative lenses?

A: OEM lenses are manufactured by Christie with optical parameters and body tolerances calibrated to original specifications, suitable for projects with strict OEM consistency requirements; Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, imaging circle, and mount matching the original machine, offering advantages in budget and lead time. Zorsika supplies both options—choose based on your project requirements.

Q: How to confirm this lens works with my machine?

A: Verify by the lens interface on the unit and panel/chip size; this article lists verified compatible models. Projectors of the same generation and brand often share interfaces. When in doubt, photograph the nameplate on your unit and send it to Zorsika technical team for confirmation.

Q: How to choose the Throw Ratio?

A: Throw Ratio = Projection Distance ÷ Screen Width. Smaller values produce larger images (short-throw/ultra-short-throw suits close-proximity small spaces), larger values require greater installation distance. Back-calculate the required throw ratio range based on your installation distance and screen size, then match it to the focal length of this model.

Q: How does 121-128102-XX Fixed ensure authenticity?

A: Zorsika provides genuine OEM channel products with original packaging and verifiable serial numbers; batch projects can request channel documentation to ensure no refurbished or second-hand salvaged parts.

Q: What to watch for when replacing the lens?

A: Always power off and wait for the cooling fan to stop before removal/installation; hold the lens by the barrel without touching the glass; gently blow off dust with an air blower; after proper installation, test focus first then tighten the mounting screws, and clean the mount and contacts.

Q: What is the lens warranty period?

A: Zorsika provides 12-month warranty on all projector lenses; normal use and non-human damage (such as impacts, water ingress, unauthorized disassembly) can be directly handled through after-sales service; warranty period is based on the shipping document date.
